Collecting diagnostics by using a Linux utility

You can use a Linux utility called ocaDRDiags to collect diagnostics from Linux-only clients. This Linux utility is installed by the OST plug-in installer in the /opt/oca directory. The tool collects the following types of information:

The diagnostics file is written to the following location: /var/log/diags_client location.

The following example shows the process for collecting the RDA with OST diagnostic logs (the root user account shown represents one that resides on the media server, and is not to be confused with a root user account on the DR Series system):

The default log level can be modified via the DR Series system CLI or GUI.

Rotating RDA with OST plug-in logs for Linux

If you set the RDA with OST plug-in log level to Debug, this can cause the plug-in log to grow in size quickly. The best practice for preventing any issues with log sizes is to rotate the plug-in logs using the logrotate utility that is commonly available on Linux-based systems.

To configure log rotation, complete the following:

The logrotate utility runs every hour, and rotates the logs whenever the log file size exceeds 10 megabytes (MB). This procedure is automated as part of the plug-in installation.

Guidelines for gathering media server information

In addition to the DR Series system diagnostics log file bundles and core files that you can collect for history and troubleshooting purposes, if you have run any RDA with OST operations, Quest recommends that you also gather some important media server-related files. This topic introduces some of these key media server files that reside on Linux and Windows platforms .

NetBackup on Linux Media Servers

Quest recommends that if core_pattern on the client is set by NAT to a specific directory, then the diagnostics script has to look into that directory for any related cores.

NetBackup on Windows Media Servers

If a server failure is involved (which could be an inapparent or silent failure), the Windows media server event log for the application could be collected by using Administrative Tools → Event Viewer. Next, check the Windows Logs → Application. Typically, the last entry marked with Error is the one for which you are searching.
