Named Pipes (im_pipe)
This module can be used to read log messages from named pipes on UNIX-like operating systems.
The im_pipe module accepts the following directives in addition to the common module directives.
If set to TRUE, this optional boolean directive instructs the module to create the directory where the Pipe pipe file is located, if it does not already exist. The default is FALSE.
This mandatory directive specifies the name of the input pipe file. The module checks if the specified pipe file exists and creates it in case it does not. If the specified pipe file is not a named pipe, the module does not start.
This directive specifies the input data format. The default value is
LineBased. See the InputType directive in the list of common module directives.
Use this directive to set the group ownership for the created socket or pipe or file. By default, this is the group NXLog is running as, (which may be specified by the global Group directive). This directive is not currently supported on Windows.
This directive specifies the permissions to use for the created socket or pipe or file. This must be a four-digit octal value beginning with a zero. By default, OS default permissions will be set. This directive is not currently supported on Windows.
Use this directive to set the user ownership for the created socket or pipe or file. By default, this is the user NXLog is running as (which may be specified by the global User directive). This directive is not currently supported on Windows.
This example provides the NXLog configuration for processing messages from a named pipe on a UNIX-like operating system.
With this configuration, NXLog reads messages from a named pipe and forwards them via TCP. No additional processing is done.
