About the NetBackup Smart Diagnosis (nbsmartdiag) utility
You can use the NetBackup Smart Diagnosis (nbsmartdiag) utility to detect performance issues, such as high CPU utilization, high memory usage, and deadlocks for the registered NetBackup processes. When nbsmartdiag detects an issue, the appropriate evidence is collected for further troubleshooting, without any user intervention. nbsmartdiag is a service or a daemon that can be deployed on a NetBackup master server, a media server, or a client.
Note:
The nbsmartdiag service is supported only on Windows and Linux (RHEL and SUSE) platforms.
Evidence is a set of information which is collected to help troubleshoot the performance of NetBackup.
A single set of evidence collected that contains:
On Windows
A process dump of the process exhibiting performance issues.
Memory Performance counters in the form of a CSV file.
Network Performance counters in the form of a CSV file.
Disk Performance counters in the form of a CSV file.
netstat command outputs for network issues.
On Linux
A process dump of the process exhibiting performance issues.
vmstat, free, top, etc. command output for memory details.
gstack, pmap of the process.
mpstat, iostat command output for Disk I/O details.
netstat command outputs for network issues.
Sample of collected evidence on Windows.

NetBackup Design does not allow the bpup command to start the nbsmartdiag service.
Cyrillic characters in the evidence path are not supported.
You can run nbsmartdiag service under local system account on Windows and under root privileges on Linux.
Java processes have a common run time name, to monitor NetBackup Admin Console use adminconsole and to NetBackup Web Management Service use nbwmc in the process names.
