I've addressed some of your questions below:
We like to set some traps or poll information via SNMP or Syslog.
Look at Chapter 24 of the Orion NPM Administrator Guide. It explains traps in detail.
I need information about how i can poll login-logout times of users and also information of getting current logged users.
You'll need the OIDs of all the items you want to poll. Then you can use the Universal Device Poller to poll them. Chapter 12 of the Orion NPM Administrator Guide will give you instructions on how.HTH,M
actually we know how to set alerts and the usage of universal device poller.
the problem is to get correct oids of systems we use.
mib browser couldn't help to solve our problem.
what else do you advise ?
