I would suggest also monitoring the daemon.log file for messages like
these (message texts are current as of 7.2.x; YMMV with other versions):

"duplicate name; pick new name or delete old one"

"Hardware Error, Diagnostic Failure on Component 0x01" (may indicate an
upside-down tape)

"cannot find slot ##### in operation slots list." (NetWorker tried to
unload a drive but had no empty slot for the tape. Rare -- and always
the result of clumsy manual intervention -- but serious)

Any message containing the string "RAP error" (depending on your
environment you may have to exclude certain subtypes of this message)

"WISS error" (this message not only lets you know about a potential
problem, it also serves to alert you about unplanned reboots)

"aborted, savegrp is already running"

"Too many open files" (rare but deadly)

"Label check failed"

Subject: Monitoring a NetWorker server

I am working with a colleague to set up some software to monitor  
processes and events on a Solaris 10 NetWorker 7.4.1 server. One thing  
that is not clear to me is how many nsrmmd processes to watch out for.  
For example, I know we need to watch out for one nsrd and one  
nsrexecd, but the number of nsrmmd processes seems to fluctuate,  
perhaps because this server shares four out of fourteen tape devices  
with a storage node via dynamic drive sharing. Can anyone shed any  
light on how many nsrmmds to look out for and recommend any other  
essential NetWorker processes to monitor?
