Device Status should have nothing to do with other tasks

With both Ping and SNMP enabled, once Ping is down (and consequently Device Status down too) Zenoss stops getting any SNMP/command events anymore.

This is what I have done to test this:

1. Enable Ping monitoring for monitored device
2. Enable SNMP monitoring for monitored device
3. Enable a specific Nagios plug-in command for monitored device
4. Drop ICMP packets with IPTables @ monitored device
5. Stop SNMP service @ monitored device

After that:

• Ping events still coming, as they should
• SNMP/command events not (monitored device not receiving any SNMP request either, checked with tcpdump)

But I was expecting:

• Monitored device to get SNMP requests
• Zenoss to track what is going on even with Ping down (my NOC can mainly have SNMP, but we do not want to Ignore Ping monitoring at all - they should coexist)

This makesSNMP/command monitoring useless when Ping is not available (and we need it this way).

What should I change to get this working for us I am able to modify the source code if pointed in the right direction.

Zenoss Core v5.0.5 here.

Thanks in advance :)

Update:I think I have finally found what I was looking for. A boolean, it seems.
