Those multiple masters in multiple networks are in separated networks each.
For example, if we install a NOM server in Symantec (yes, inside a Symantec building) will it be able to see/manage/serve a NetBackup master server in my company's data centre?
That's what I have - all my master servers are in their independent & separated networks, there is no one network (to host NOM server) that can talk to all those master servers at a time.
Of course I can access them all from my laptop, but I open VPN, I don't think NOM is intelligent enough to open a VPN session.
Yes, I can't avoid running whatever script/tool/product on each master/network.
Communicate back "is possible" via SMTP protocol - email, I mean.
That's why I'm thinking of running cron'ed script on each master and send email notifications to my work email.
(Again, yes, NOM can send email, bu I explained earlier why I do not want / can not use NOM)
I found standard UNIX "ps -ef" command will reveal the bpjava-susvc session's start time and logon IDs (the line with PPID 1, there's one line per session) so I'm thinking of writing a script to run ps on regular interval and then process the output to keep track of the user logon/off time (roughly)... that's what I have found so far.
Will advise you all once I finish the script and put it in the downloads section.
*EDIT* - yes, I think I'm lucky that I do not need to worry about sys admin or network, only Backup is my job
