Detailed SNMP Agent info in release 5.1.2
Hi *,
In Enterprise Manager, the SNMP Agent appears to be running, but according to netstat -a, no process listens on the configured port. I would like to look into the "real" configuration for the agent to verify the port number I configured with Enterprise Manager really shows up in the configuration files. Where are those located? All I can find is the configuration for the SNMP webapp wich I suspect is separated from the agent itself. I might be totally blind or there might be something wrong with the installation.
Thanks,
Jonas

Jonas,
The CAPS SNMP Agent really meets two requirements:
a) The most normal use is to forward alerts to a valid management server (could be a simple commandline snmptrad program, Adventnet, HP OV, SunView, Tivoli..) as SNMP traps.
b) It is possible to use the SNMP MIB (Managed Information Base) from a valid MIB Browser, where it is possible to get similar information as is possible to get via the EM web interface. Some tools have an "added value" in that it is possible to for example monitor the queue depth of queues graphically over a period of time.
The SNMP Trap forwarder does not listen to a port - it forwards traps to a receiver. The default port is 162 but can be changed in the EM SNMP Configuration panel.
The orchestration part and MIB access does listen on a UDP port. Usually OS SNMP agents listen to 161, which means that it is a good idea to change the address to something like 16100.
You will find the configuration files (where it is possible to add additional info than what is offered by the EM panel, for example SNMP version levels) under emanager\server\monitor\snmpagent\config.
When you perform a netstat, you should see something like:
UDPmymachine:16100*:*
.. for an SNMP agent expecting MIB requests.
If 16100 had been added to the OS services file, you would see the service name corresponding to the port instead.
