Pid

[arjun7]

What is Pid ? how to see the Pid details? how Pids are useful while troubleshooting?

[Deb_Wilmot · Accepted solution]

Pids are Process ID's.

They're useful when troubleshooting because we know which process ID to look for in the log file as there may be hundreds/thousands of them.

You can view the pids by runnin the following:

  bpps -x (UNIX)

  bpps (Windows)

Example output UNIX:

Saber >> bpps -x

BTW - TID's are different.  They're thread ID's.  Multithreaded processes can have numerous threads associated with them.  Knowing the thread ID helps to follow the individual threads as lines right next to each other may not be associated with the same call.

I.e. here is an example of a TID (using vxlogview output):
11/05/13 00:20:13.351 [Application] NB 51216 nbpem 116 PID:753 TID:15 File ID:116 [jobid=664 job_group_id=664 client=abc123 type=4 server=saber task=ID:1015d7538 CTX:1015ac0a0 policy=abc123] [Error] V-116-85 backup of client abc123 exited with status 48 (client hostname could not be found)

In this case if I wanted to see what was going on with this call, I would follow TID 15.

The trouble shooting guide has more information on troubleshooting NetBackup.  Check out the 7.6 Guide as we've made a lot of improvements to it. :)

Have a look at this definition: http://en.wikipedia.org/wiki/Process_ID 

It NBU terms, you may have more than one backup running on a media server at the same time. 
Each backup job will have its own bpbrm and bptm process on the media server. Same goes for all NBU processes on master, media server(s) and client(s).

NBU makes troubleshooting easier by adding PID for each job/stream in the log file. This means that when you troubleshoot a specific job, you only need to find the PID for that job in the log that you are looking at and ignore other PIDs. 

NBU makes it even easier by displaying PIDs for the different processes (e.g. bpbrm, bptm, bpbkar, etc) in Activity Monitor.

thank you very much to all for explaian about Pids
