Insight Manager and SNMP polling not listening

[ben79]

Hi

I am trying to get Insight Manager to listen for SNMP Traps instead of polling all our devices. Does anyone know how to set this up.

Cheers

HP SIM does both. Polling is an important backup method because SNMP traps are not guaranteed for delivery. You can customize the frequency of polling in Tasks & Logs --> Scheduled Tasks if you think that the 5 minute default frequency is too often.

thank you for that info. Since my post i have moved on a bit and discovered that our problem is a bit different. we are getting 1000's of AuthentiactionFailure SNMP traps sent to our IM Server. I inititally thought it was IM polling our devices. but arfter running a packet capture on one of our agents, i saw that the server was sending out these traps every three seconds and IM is not initiating the trap. We are trying to find out what is causing our servers to send these traps as theya are all using the same community string name, and when you analyse the AuthFailure traps they are using the correct community string to send the trap back. very strange.

You need to look for another source of SNMP traffic on the network...looks like something else is trying to query with the wrong community string all of your devices causing the authentication failure traps to be sent back to HP SIM...

yeah thats what i've been trying to do. i disabled IM and MOM so no traffic from those boxes was being sent to my test box. i did a 10 min packet sniff and every 3 secs the box sent an SNMP trap but there are no packets to instigate this trap. it must be a network monitoring tool
