Here is an interesting discussion we have had privately but I guess it must be public.
Dear all, you know that we do not have service hierarchy in Poller. The only one is that established by what we called critical service. We should address some use case when using the really awesome SnmpMonitor, in fact what to do when the Agent is Down? Clearly here we have a dependency from the availability of the agent and if for example I'm monitoring some process using process table or some net snmp mib extention I can report that the service is down while it is just running! My idea is to add a new parameter to SnmpMonitor in which I can state if the Agent is not available do not report unavail status. Somethink like dependOn=true or false.

I was not aware of that status until just now when I went looking for it :) Seems not widely used, but the MailTransportMonitor can return it. -jeff When you use the SnmpMonitor to get a specific oid and a given value you just assert that there is a monitored service that depends on the snmp agent availability. If the agent is down you are not aware of the Service Status. Actually the SnmpMonitor when you got a null SnmpValue that means no response from Agent create a status unavailable. This is not true, instead is true if you are monitoring the SNMP protocol it is not true when you are monitoring something elese using the SNMP protocol. This is a dependency trouble.
