How to do a few things?

Hello,

We are trying to migrate from Nagios to OpManager and are having a few problems.

1. I can't get a Cisco 3750 switch to monitor properly. The credentials test passes for both snmp and cli but testing the monitors fails. I think this is due to the snmp setup on the switch, you have to create a user and assign the user to a group etc. Any help on this?

2. Is there any easy way of transferring Nagios checks to OpManager? We have a lot of perl scripts which nagios calls with an argument which then use snmpget to check the status of our servers.

3. Is there a way to create custom checks either by WMI scripts or by checking the return(error) code of a script/program that OpManager would run?

Thanks.

Dave
