Instructions

NetWorker sends messages to two types of logs. Plain text log files that are saved with the .log extension and unrendered log files that are saved with the .raw extension. The .log files and the messages that appear in NMC use the locale setting of the service that generates the log message. To view the contents of .log files, use any text editor. Before you can view .raw files in a text editor, render the .raw file into the locale of the local machine. You can manually render the raw log files or configure NetWorker to render the log files at runtime.

CloudBoost - NetWorker Client The following log files in the
/nsr/logs/cloudboost directory:

MagFS.log.ERROR.date-timestamp.pid.txt
MagFS.log.FATAL.date-timestamp.pid.txt
MagFS.log.INFO.date-timestamp.pid.tx		 These files appear on a client direct-enabled NetWorker Client and contain information about data stored on a CloudBoost device. The severity of the message determines which log file that error message is written to. The maximum size of the log files is 100 MB.

Before a client direct backup, the save process checks the size of the file. When the maximum size is reached, save starts an automatic trimming mechanism, which renames and compresses the log file. The maximum number of versions for a file is 10. When renamed log files reach the maximum version value, NetWorker removes the oldest log as a new version is created.
 
NOTE: The Troubleshooting manual backups section of the NetWorker Administration Guide describes how to use the CB_LOG_DIR_LOCATION environment variable to change the default log file location.
CloudBoost - CloudBoost Appliance The following log files in the /nsr/logs/cloudboost directory:

MagFS.log.ERROR.date-timestamp.pid.txt
MagFS.log.FATAL.date-timestamp.pid.txt
MagFS.log.INFO.date-timestamp.pid.txt		 These files appear on the CloudBoost appliance and contain information about operations that are performed on a CloudBoost device. The severity of the message determines which log file that error message is written to. The maximum size of the log files is 100 MB.

When the maximum size is reached, the nsrmmd process starts an automatic trimming mechanism, which renames and compresses the log file. The maximum number of versions for a file is 10. When renamed log files reach the maximum version value, NetWorker removes the oldest log as a new version is created.

NetWorker Virtual Edition (NVE) Specific Logs:

In addition to the standard NetWorker logs detailed above, the NVE has some additional logs regarding its deployment and upgrade processes.

The NVE's avinstaller process provides a web interface to access the NVE deployment and upgrade user interface. The avinstaller service has the following logs:

  • /space/avamar/var/avi/server_log/avinstaller.log
  • /space/avamar/var/avi/server_log/aviserver.log
  • /space/avamar/var/avi/server_log/avitask.log.0

While the NVE is performing an upgrade or rollup, the following logs can be used to identify the progress of the upgrade or any errors:

  • /data01/avamar/repo/temp/*/tmp/workflow.log
  • /data01/avamar/repo/temp/*/tmp/err.log

All historic NVE upgrade logs can be found under:

  • /usr/local/avamar/var/avi/server_data/package_data/PACKAGE_NAME

NveOsRollup also logs information under /tmp/sec_install_os_errata_sles.pl.log; however, this log is removed after the system reboots.

NOTE: Additional information is available through: NVE: Upgrade/Install Failure Triage Guide.
