  3. Use SFTP or a similar secure method to transfer the archive to the target server.

  4. Log in to the target server and extract the contents of the archive.

    # tar xjf nxlog-6.3.9425_sles15_x86_64.tar.bz2

  5. Optional: To change the NXLog user and group for the installation, set the NXLOG_USER and NXLOG_GROUP environment variables. During installation, a new user and a new group will be created based on these environment variables. They will be used for User and Group directives in nxlog.conf, and for the ownership of some directories under /opt/nxlog. Specifying an already existing user or group is not supported. The created user and group will be deleted on NXLog removal.

    # export NXLOG_USER=nxlog2
    # export NXLOG_GROUP=nxlog2
  6. Download the public key file from the NXLog’s public contrib repository and import it to the RPM database.

    # rpm --import nxlog-pubkey.asc

    For more details about the package verification, see the Signature Verification for RPM Packages section in the User Guide.

  7. Install the required NXLog packages and their dependencies (this example installs the main NXLog package only).

    # zypper install nxlog-6.3.9425_sles15.x86_64.rpm
  8. Configure NXLog by editing /opt/nxlog/etc/nxlog.conf. General information about configuring NXLog can be found in Configuration. For more details about configuring NXLog to collect logs on Linux, see the GNU/Linux summary.

  9. Verify the configuration file syntax.

    # /opt/nxlog/bin/nxlog -v
    2020-10-17 08:05:06 INFO configuration OK
  10. Start the service using the service command:

    # systemctl start nxlog.service
  11. Check that the NXLog service is running with the systemctl command.

    # systemctl | grep nxlog
    loaded active running  NXLog daemon


To update an NXLog installation to the latest release, use zypper as in the installation instructions above. It is recommended to make a backup of the configuration files before starting this process.

# zypper install nxlog-6.3.9425_sles12.x86_64.rpm

To replace a trial installation of NXLog Enterprise Edition with a licensed copy of the same version, follow the installation instructions.

The same user and group will be used for the upgrade as was used for the original installation (see installation user and group above). Changing to a different user and group during upgrade is not supported.


To uninstall NXLog, use zypper remove. To remove any packages that were dependencies of NXLog but are not required by any other packages, include the --clean-deps option. Verify the operation before confirming!

# zypper remove 'nxlog*'
This procedure may not remove all files that were created while configuring NXLog. Likewise, any files created as a result of NXLog’s logging operations will not be removed. To find these files, examine the configuration files that were used with NXLog and check the installation directory (/opt/nxlog).
