Understanding RDA with OST Plug-In Diagnostic Logs

Understanding RDA with OST Plug-In Diagnostic Logs

You can collect diagnostic logs for supported DMAs with the RDA with OST plug-in.

 
NOTE: The directory location, C:\ProgramData, is considered to be a hidden directory on Windows-based systems. However, you can copy and paste C:\ProgramData\Dell\DR\log\ into your Internet Explorer Address bar or you can enter this into the Windows command prompt window (Start→ All Programs→ Accessories→ Command Prompt).

For more information about RDA with OST plug-ins and logs, see the topics that follow.

Rotating RDA with OST Plug-In Logs for Windows

Rotating RDA with OST Plug-In Logs for Windows

By default, the Windows log rotation size is set at 10 megabytes (MB). Once a log file has been reached this size, the RDA with OST plug-in automatically renames the existing log file, libstspiDell.log to libstspiDell.log.old, and creates a new log.

Modifying Log Rotation Size

To modify the log rotation size, you can edit the following registry key value:

Immediately after modifying this value, the new rotation size value takes effect (meaning that you do not have to restart the backup process).

Collecting Diagnostics Using a Linux Utility

Collecting Diagnostics Using a Linux Utility

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

•
var/log/libstspiDell.log.*
•
usr/openv/netbackup/logs
•
usr/openv/logs/nbemm/
•
usr/openv/logs/nbrmms/

The Dell_diags 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):

root@oca3400-74 ~]# ./Dell_diags –collect
Collecting diagnostics...Done
Diagnostics location: /var/log/diags_client//oca3400-74_2012-02-27_23-02-13.tgz

The default log level is set to Error in the OST plug-in, is user-configurable, and can be modified via the DR Series system CLI or GUI.

Rotating RDA with OST Plug-In Logs for Linux

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 quickly grow in size. 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:

Create a file in /etc/logrotate.d/, name it “ost”, and add the following entries:
/var/log/libstspiDell.log {
rotate 10
size 10M
copytruncate
}
2.
Create a file in /etc/cron.hourly/, name it “ost_logrotate.cron”, and add the following entries:
#!/bin/bash
/usr/sbin/logrotate /etc/logrotate.d/ost

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.
