Microsoft Azure (im_azure)

This module can be used to collect logs from Microsoft Azure applications. It can operate in three different modes to connect to the following data sources:

  1. Azure Table Storage

  2. Azure Blob Storage

  3. Azure Log Analytics workspace

To examine the supported platforms, see the list of installation packages.

Storage setup

For Blob or Table modes, Azure web application logging and storage can be configured from the Azure Management Portal by following these steps:

  1. After logging in to the Portal, open the left portal menu, select Storage accounts, and then select Create.

  2. Create the new storage account, providing a storage account name, region, and redundancy type. Take note of the storage name, you will need to specify this value in the NXLog Agent configuration. More information on the storage settings can be found in the Microsoft documentation on how to Create a storage account.

  3. On the Review + create tab, click Create and wait for storage setup to complete.

  4. Navigate to your app and select App Service logs.

  5. Select On for Application Logging (Blob).

  6. Configure Storage Settings corresponding with the storage account created above. More information on the configuration settings can be found in the Microsoft documentation on how to Enable diagnostic logging for apps.

  7. Confirm the changes by clicking Save, then restart the service. Note that it may take a while for Azure to create the table and/or blob in the storage.

Log Analytics workspace setup

For Analytics mode, an application needs to be registered and granted the necessary permissions to read from the Log Analytics workspace. Follow the instructions to Register an application in Microsoft Entra ID.

Once you have created the new application, open the settings for your new app and take note of the Application (client) ID. You will need to specify this value for the ClientID directive.

Grant the application permission to use the Log Analytics API and create a client secret:

  1. From the left menu, select API permissions and then + Add a permission. Select APIs my organization uses and choose Log Analytics API.

  2. Select Application permissions for the type of permission required, and Data.Read for the permission.

  3. Click Add permissions to create the permission.

  4. From the left menu, select Certificates & secrets and then + New client secret. Enter a description and expiration period, then click Add.

  5. Take note of the Value of the new secret, you will need to specify this for the SharedKey directive.

Add the app to your Log Analytics workspace:

  1. Go to your Log Analytics workspace and take note of the Workspace ID. You will need to specify this value for the WorkspaceID directive.

  2. From the left menu, select Access control (IAM). Click + Add and select Add role assignments.

  3. Choose Log Analytics Reader for role, select the application registered above, and click Save.

Configuration

The im_azure module accepts the following directives in addition to the common module directives.

Required directives

The following directive is required for the module to start.

Mode

This mandatory directive specifies the type of service the module should connect to. It accepts one of the following values: Table, Blob, Analytics. Each mode requires a corresponding set of mandatory directives.

Table mode directives

The following are mandatory directives when using Table mode.

SharedKey

This directive specifies the authentication key to use for connecting to the Azure Storage account.

StorageName

This directive specifies the name of the storage account to connect to.

TableName

This directive specifies the storage table from which to collect logs.

Blob mode directives

The following are mandatory directives when using Blob mode.

BlobName

This directive specifies either the name of the blob container or the path of a single blob (formatted as container/blob) from which to collect logs.

SharedKey

This directive specifies the authentication key to connect to the Azure Storage account.

StorageName

This directive specifies the name of the storage account to connect to.

Analytics mode directives

The following are mandatory directives when using Analytics mode.

ClientID

The Application (client) ID of the application that will be used to authenticate with Microsoft Entra ID.

SharedKey

The Microsoft Entra ID application client secret.

TableName

This directive specifies the storage table from which to collect logs.

TenantID

The ID of the Microsoft Entra tenant to connect to.

WorkspaceID

This directive specifies the workspace ID of the Log Analytics account from which to collect logs.

HTTPS directives

The following directives configure secure data transfer via HTTPS.

HTTPSAllowExpired

Set this directive to TRUE to allow connections with remote hosts presenting an expired certificate. The default is FALSE; the module rejects connections with expired certificates. This directive only takes effect when HTTPSRequireCert is set to TRUE.

HTTPSAllowHostnameValidation

Set this directive to TRUE to require that the certificate FQDN matches the server hostname before allowing a connection. The default is FALSE; the module does not validate the remote server hostname.

HTTPSAllowUntrusted

Set this directive to TRUE to allow connections with remote hosts regardless of certificate verification results. The default is FALSE; the module only accepts connections with trusted certificates.

HTTPSCADir

Set this directive to the path of a directory containing Certificate Authority (CA) certificates. The module uses these certificates to verify the certificate presented by the remote host. Name the certificate files using the OpenSSL hashed format: the hash of the certificate followed by .0, .1, and so on. To find the hash of a certificate using OpenSSL:

$ openssl x509 -hash -noout -in ca.crt

For example, if the certificate hash is e2f14e4a, name the certificate file e2f14e4a.0. If there is another certificate with the same hash, name it e2f14e4a.1, and so on.

To trust a remote host’s self-signed certificate, include a copy of it in this directory.

If this directive isn’t specified, NXLog Agent falls back to the default operating system root certificate store. Unix-like operating systems commonly store root certificates in /etc/ssl/certs. Windows operating systems use the Windows Certificate Store, while macOS uses the Keychain Access Application as the default certificate store. See Certificate Authority (CA) certificates in the NXLog Platform User Guide for more information on using this directive.

In addition, Microsoft’s PKI repository contains root certificates for Microsoft services.

This directive is mutually exclusive with the HTTPSCAThumbprint, HTTPSCAPattern, and HTTPSSearchAllCertStores directives.

HTTPSCAFile

Set this directive to the path of the Certificate Authority (CA) certificate used to verify the certificate presented by the remote host. To trust a remote host’s self-signed certificate, specify the remote host’s certificate itself. For certificates signed by an intermediate CA, the specified certificate must contain the complete certificate chain (certificate bundle).

This directive is mutually exclusive with the HTTPSCAThumbprint, HTTPSCAPattern, and HTTPSSearchAllCertStores directives.

HTTPSCAPattern

Set this directive to a PCRE2-compliant regular expression to locate a suitable Certificate Authority (CA) certificate. This directive is supported on Windows and macOS.

On Windows, the certificate must be in the Windows Certificate Store. On macOS, the certificate must be in the system keychain.

NXLog Agent matches the pattern against a string built from the certificate’s fields in this order:

SUBJECT=<value>, CN=<value>; DN=CN=<value>, O=<value>, OU=<value>, L=<value>, ST=<value>, C=<value>; SAN=<value>

The pattern doesn’t need to match every field. Include only the fields you want to match, and use .*? to skip over the rest.

For example, the following pattern matches only the DN and SAN fields:

HTTPSCAPattern    'DN=CN=SERVER01\.example\.com.*?SAN=DNS:SERVER01\.example\.com'

This produces the following output in the NXLog Agent log file:

matching pattern [DN=CN=SERVER01\.example\.com;.*?SAN=DNS:SERVER01\.example\.com] to certificate [SUBJECT=US, ClientState, ClientCity, ClientCompany, ClientUnit, SERVER01.example.com, CN=SERVER01.example.com; DN=CN=SERVER01.example.com, O=ClientCompany, OU=ClientUnit, L=ClientCity, ST=ClientState, C=US; SAN=DNS:SERVER01.example.com; DNS:www.SERVER01.example.com; IP:127.0.0.3; ]

If the pattern matches multiple certificates, NXLog Agent uses the first match. If the certificate changes, restart NXLog Agent to apply the new certificate.

This directive is mutually exclusive with the HTTPSCAThumbprint, HTTPSCADir, HTTPSCAFile, and HTTPSSearchAllCertStores directives.

On macOS, keychain behavior and certificate requirements depend on your operating system version. Newer versions enforce stricter rules on certificate algorithms and key sizes. A certificate and private key may be imported into the keychain, yet remain unusable if they do not comply with the current macOS requirements. After importing, you may also need to give NXLog Agent permission to use the certificate in the keychain.

Check your operating system documentation to find out which certificates are trusted and valid. See also Apple’s certificate requirements for macOS.

HTTPSCAThumbprint

Set this directive to the thumbprint of the Certificate Authority (CA) certificate used to verify the certificate presented by the remote host. This directive is supported on Windows and macOS.

On Windows, copy the hexadecimal fingerprint string from Windows Certificate Manager (certmgr.msc). The certificate must be in a Windows certificate store accessible by NXLog Agent.

On macOS, obtain the hexadecimal fingerprint string from the Keychain Access application. The certificate must be accessible in the system keychain.

Whitespaces and colons are automatically removed.

This directive is mutually exclusive with the HTTPSCADir, HTTPSCAFile, HTTPSCAPattern, and HTTPSSearchAllCertStores directives.

On macOS, keychain behavior and certificate requirements depend on your operating system version. Newer versions enforce stricter rules on certificate algorithms and key sizes. A certificate and private key may be imported into the keychain, yet remain unusable if they do not comply with the current macOS requirements. After importing, you may also need to give NXLog Agent permission to use the certificate in the keychain.

Check your operating system documentation to find out which certificates are trusted and valid. See also Apple’s certificate requirements for macOS.

HTTPSCertFile

Set this directive to the path of the certificate file to present to the remote host during the HTTPS handshake.

HTTPSCertKeyFile

Set this directive to the path of the private key file corresponding to the certificate specified by HTTPSCertFile.

HTTPSCertPattern

Set this directive to a PCRE2-compliant pattern to identify the certificate and its corresponding private key. This directive is supported on Windows and macOS.

NXLog Agent matches the pattern against a string built from the certificate’s fields in this order:

SUBJECT=<value>, CN=<value>; DN=CN=<value>, O=<value>, OU=<value>, L=<value>, ST=<value>, C=<value>; SAN=<value>

The pattern doesn’t need to match every field. Include only the fields you want to match, and use .*? to skip over the rest.

On Windows, import the certificate in PFX format into the Local Computer\Personal certificate store.

On macOS, ensure the certificate and its private key are present in the System Keychain (/Library/Keychains/System.keychain).

During configuration, NXLog Agent resolves this directive into the corresponding HTTPSCertThumbprint value. If the pattern matches multiple certificates, NXLog Agent uses the first match. This directive is not dynamic; restart NXLog Agent to apply a changed certificate.

We recommend keeping the certificate storage referenced by this directive well-maintained for optimal performance.

This directive is mutually exclusive with the HTTPSCertThumbprint, HTTPSCertFile and HTTPSCertKeyFile directives.

Configuration examples:

HTTPSCertPattern    $hostname + 'Cert'

or

HTTPSCertPattern    DN=CN=Client\.example\.com;.*?SAN=DNS:Client\.example\.com

This produces the following output in the NXLog Agent log file:

matching pattern [DN=CN=Client\.example\.com;.*?SAN=DNS:Client\.example\.com] to certificate [SUBJECT=US, ClientState, ClientCity, ClientCompany, ClientUnit, Client.example.com, CN=Client.example.com; DN=CN=Client.example.com, O=ClientCompany, OU=ClientUnit, L=ClientCity, ST=ClientState, C=US; SAN=DNS:Client.example.com; DNS:www.Client.example.com; IP:127.0.0.3; ]

On macOS, keychain behavior and certificate requirements depend on your operating system version. Newer versions enforce stricter rules on certificate algorithms and key sizes. A certificate and private key may be imported into the keychain, yet remain unusable if they do not comply with the current macOS requirements. After importing, you may also need to give NXLog Agent permission to use the certificate in the keychain.

Check your operating system documentation to find out which certificates are trusted and valid. See also Apple’s certificate requirements for macOS.

HTTPSCertThumbprint

Set this directive to the thumbprint of the certificate to present to the remote host during the HTTPS handshake. Whitespaces and colons are automatically removed. This directive is supported on Windows and macOS.

On Windows, copy the hexadecimal fingerprint string from Windows Certificate Manager (certmgr.msc). Import the certificate to the Local Computer\Personal certificate store in PFX format. To create a PFX file from the certificate and private key using OpenSSL:

$ openssl pkcs12 -export -out server.pfx -inkey server.key -in server.pem

When the global directive UseCNGCertificates is set to FALSE, the private key must be exportable.

  • If you generate the certificate request using Windows Certificate Manager, enable the Make private key exportable option from the certificate properties.

  • If you import the certificate with the Windows Certificate Import Wizard, make sure that the Mark this key as exportable option is enabled.

  • If you migrate the certificate and associated private key from one Windows machine to another, select Yes, export the private key when exporting from the source machine.

When UseCNGCertificates is set to TRUE, the private key does not need to be exportable. For example, private keys stored on a TPM are always non-exportable.

On macOS, obtain the hexadecimal fingerprint string from the Keychain Access application. The certificate and its associated private key must be present in the System Keychain (/Library/Keychains/System.keychain).

For example:

HTTPSCertThumbprint    7c2cc5a5fb59d4f46082a510e74df17da95e2152

On macOS, keychain behavior and certificate requirements depend on your operating system version. Newer versions enforce stricter rules on certificate algorithms and key sizes. A certificate and private key may be imported into the keychain, yet remain unusable if they do not comply with the current macOS requirements. After importing, you may also need to give NXLog Agent permission to use the certificate in the keychain.

Check your operating system documentation to find out which certificates are trusted and valid. See also Apple’s certificate requirements for macOS.

HTTPSCRLDir

Set this directive to the path of a directory containing certificate revocation list (CRL) files. The module uses these files to reject connections from hosts presenting a revoked certificate. Name the files using the OpenSSL hashed format: the hash of the issuer followed by .r0, .r1, and so on. To find the hash of the issuer of a CRL file using OpenSSL:

$ openssl crl -hash -noout -in crl.pem

For example, if the hash is e2f14e4a, name the file e2f14e4a.r0. If there is another file with the same hash, name it e2f14e4a.r1, and so on.

HTTPSCRLFile

Set this directive to the path of the certificate revocation list (CRL) file used to reject connections from hosts presenting a revoked certificate. To generate a CRL file using OpenSSL:

$ openssl ca -gencrl -out crl.pem

HTTPSDHFile

Set this directive to the path of a file containing Diffie-Hellman parameters for key exchange. Generate the parameters using dhparam(1ssl). If this directive is not set, the module uses default parameters. See the OpenSSL Wiki for further details.

HTTPSKeyPass

Set this directive to the passphrase of the private key specified by HTTPSCertKeyFile. This directive applies only to encrypted private keys.

To generate a private key with Triple DES encryption using OpenSSL:

$ openssl genrsa -des3 -out server.key 2048

HTTPSLoadCertificateChains

Set this directive to TRUE to load the full certificate chain from the PEM file referenced by HTTPSCertFile, which may contain a single certificate or the complete chain. The default is FALSE; the module loads certificates from the operating system certificate store instead.

This directive is only supported on Windows.

HTTPSRequireCert

Set this directive to TRUE to require the remote host to present a certificate during the HTTPS handshake. The module refuses the connection if no certificate is presented. The default is TRUE.

HTTPSSearchAllCertStores

Set this directive to TRUE to load all available Windows certificates into NXLog Agent for use during remote certificate verification. Any required certificates must be in a Windows certificate store accessible by NXLog Agent. This directive is only supported on Windows and is mutually exclusive with the HTTPSCAThumbprint, HTTPSCAPattern, HTTPSCADir, and HTTPSCAFile directives.

HTTPSSSLCipher

Set this directive to override the permitted cipher list for TLSv1.2 and below. Use the format described in the ciphers(1ssl) man page. For example, specify RSA:!COMPLEMENTOFALL to include all ciphers with RSA authentication but exclude ciphers without encryption.

If RSA or DSA ciphers with Diffie-Hellman key exchange are used, set HTTPSDHFile to specify custom Diffie-Hellman parameters.

HTTPSSSLCiphersuites

Set this directive to override the permitted cipher list for TLSv1.3. Use the same format as HTTPSSSLCipher. Refer to the OpenSSL documentation for a list of valid TLS v1.3 cipher suites. The default is:

TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_GCM_SHA256

HTTPSSSLCompression

Set this directive to TRUE to compress data using zlib when sending over the network. The default is FALSE; the module sends data without compression.

Some Linux distributions, including Debian, provide an OpenSSL library without zlib support. The module emits a warning on startup if compression support is missing. The generic deb/rpm packages are bundled with a zlib-enabled libssl library.

HTTPSSSLProtocol

Set this directive to restrict the TLS/SSL protocols the module accepts. Specify a comma-separated list of the following values: SSLv2, SSLv3, TLSv1, TLSv1.1, TLSv1.2, and TLSv1.3. The default is TLSv1.2 and TLSv1.3. The OpenSSL library shipped by some Linux distributions does not support SSLv2 and SSLv3; these protocols will not work even if specified here.

HTTPSTLSCertLog

Set this directive to TRUE to log the remote host’s certificate details during the HTTPS handshake. When available, the module logs the Subject, Issuer, NotBefore, and NotAfter fields to the NXLog Agent log file. The default is FALSE.

This directive depends on the values of the HTTPSAllowUntrusted and HTTPSRequireCert directives:

HTTPSAllowUntrusted HTTPSRequireCert Outcome

FALSE

FALSE

Output depends on HTTPSTLSCertLog value

FALSE

TRUE

Output depends on HTTPSTLSCertLog value

TRUE

FALSE

No output regardless of HTTPSTLSCertLog value

TRUE

TRUE

Output depends on HTTPSTLSCertLog value

Sigalgs

Set this directive to the signature algorithm parameter to pass to the Windows SSL library. Accepted values depend on the available encryption providers. This directive is only supported on Windows.

SNI

Set this directive to the hostname to use for Server Name Indication (SNI) in HTTPS mode. If not set, the module uses the hostname specified in the URL directive.

UseCNGCertificates

Set this directive to TRUE to use the Windows Cryptography API: Next Generation (CNG) to access the private keys of certificates identified by a thumbprint. This directive is only supported on Windows.

Optional directives

InputType

This directive is identical to the InputType common module directive.

The default is LineBased, meaning the module expects CRLF as the record terminator on Windows or LF on Unix.

LocalPort

This optional directive specifies the local port number of the connection. If not specified, a random high port number will be used, which may be unsuitable for firewalled network environments.

PollInterval

This directive specifies how frequently the module will check for new events, in seconds. If this directive is not specified, it defaults to 1 second. Fractional seconds may be specified (PollInterval 0.5 will check twice every second).

Reconnect

Set this directive to the number of seconds to wait between reconnection attempts. If you do not set this directive, the module starts with a 1 second interval and doubles it after each failed attempt, resetting to 1 second once it reconnects successfully.

Setting this directive on multiple systems can cause them to send reconnection requests to the same destination at the same time, potentially overloading it. This can also cause NXLog Agent to consume unusually high system resources or become unresponsive.

ReconnectOnData

Set this directive to TRUE to have the module reconnect to the remote host only when it has data to send, instead of keeping the connection open at all times. The default is FALSE; the module always keeps a connection open with the remote host.

ReadFromLast

This boolean directive instructs the module on where to start reading events from the log source when NXLog Agent starts.

When TRUE, NXLog Agent will only read events logged after NXLog Agent started, unless SavePos is TRUE and a saved position for this log source exists in the cache file.

When FALSE, NXLog Agent will read all events from the log source, unless SavePos is TRUE and a saved position for this log source exists in the cache file.

The default is TRUE.

The following matrix shows the outcome of this directive in conjunction with the SavePos directive:

ReadFromLast SavePos Saved position Outcome

TRUE

TRUE

Yes

Reads events from the saved position.

TRUE

TRUE

No

Reads events that are logged after NXLog Agent is started.

TRUE

FALSE

Yes

Reads events that are logged after NXLog Agent is started.

TRUE

FALSE

No

Reads events that are logged after NXLog Agent is started.

FALSE

TRUE

Yes

Reads events from the saved position.

FALSE

TRUE

No

Reads all events.

FALSE

FALSE

Yes

Reads all events.

FALSE

FALSE

No

Reads all events.

If the NoCache directive is TRUE, it overrides the SavePos directive. In this case, the module behaves as if SavePos is FALSE.

SavePos

Set this directive to TRUE to save the position of the last processed event before NXLog Agent exits. On the next startup, the agent reads the saved position from the cache file and resumes from that point. Together with the ReadFromLast directive, this directive allows the agent to continue reading events from the saved position.

The default is TRUE; the position of the last read event is saved and will be read from the cache file on the next startup.

If the NoCache directive is TRUE, it overrides the SavePos directive. In this case, the module behaves as if SavePos is FALSE.

URL

This directive specifies the URL for connecting to the storage account. The module works in a failover configuration if additional URL directives are specified on new lines. If the first URL is unreachable, the module automatically fails over to the next one. If the last URL is unreachable, the module fails over to the first URL.

If this directive is not specified, it defaults to http://<storagename>.<table|blob>.core.windows.net or to https://api.loganalytics.io depending on the mode. If defined, the value must start with http:// or https://.

HTTP is only supported for table or blob storage and the storage account must have the Require secure transfer for REST API operations security setting disabled. Log Analytics workspaces require HTTPS.

Examples

Example 1. Collecting logs from Azure Table Storage

When in Table mode, im_azure expects a table containing a Message field. The value of this field is made available in the $raw_event field.

This configuration collects logs from a table and converts the data to JSON format using the xm_json extension module. Since the configuration uses a secure URL, the HTTPSCADir is specified and points to a folder that contains the Trusted Root CA certificates on the machine. Alternatively, the HTTPSCAFile directive can be used to specify a file containing the complete certificate chain for the Azure server, or the HTTPSAllowUntrusted directive to accept all certificates.

nxlog.conf
<Extension json>
    Module         xm_json
</Extension>

<Input azure_table>
    Module         im_azure
    Mode           Table

    URL            https://<storage_name>.table.core.windows.net/
    HTTPSCADir     /path/to/trusted/ca/cert/store

    SharedKey      storage_access_key
    StorageName    storage_name
    TableName      storage_table_name

    Exec           $Message = $raw_event; to_json();
</Input>
Input sample

The following is a log record stored in an Azure table. It contains a Message field and thus conforms to im_azure's data format requirements.

  "Message": "This is test message 1"
}
Example 2. Collecting logs from Azure Blob Storage

When in Blob mode, im_azure expects data to be in CSV format and contain the following header:

date,level,applicationName,instanceId,eventTickCount,eventId,pid,tid,message,activityId

This configuration collects logs from a blob container and converts the data to JSON format using the xm_json extension module. Since the configuration uses a secure URL, the HTTPSCADir is specified and points to a folder which contains the Trusted Root CA certificates on the machine. Alternatively, the HTTPSCAFile directive can be used to specify a file containing the complete certificate chain for the Azure server, or the HTTPSAllowUntrusted directive to accept all certifcates.

nxlog.conf
<Extension json>
    Module         xm_json
</Extension>

<Input azure_blob>
    Module         im_azure

    SharedKey      storage_access_key
    StorageName    storage_name

    Exec           $Message = $raw_event; to_json();
</Input>
Input sample

The following is a log record conforming to the CSV data format expected by im_azure.

  "SourceModuleName": "azure_blob",
  "SourceModuleType": "im_azure",
  "Message": "This is test message 1"
}
Example 3. Collecting logs from Azure Log Analytics workspace

This configuration collects logs from an AuditLogs table in Azure Log Analytics workspace. im_azure receives records from the Log Analytics API in JSON format, which it then parses into structured data and writes each record as a list of key-value pairs to the $raw_event field.

nxlog.conf
<Input azure_workspace>
    Module                 im_azure
    Mode                   Analytics

    # Since the API uses HTTPS, SSL must be configured
    HTTPSAllowUntrusted    TRUE

    ClientID               ms_entra_app_id
    SharedKey              ms_entra_app_client_secret
    TenantID               ms_entra_tenant_id
    WorkspaceID            workspace_id
    TableName              AuditLogs
</Input>
Output sample

The following is a record from the AuditLog table after it was processed by NXLog Agent.
