Fairly basic question I guess. I am adding nodes and deciding what to monitor in List resources. Can anyone tell me what teh following actually monitors. There seems to be little documentation that actually specifies this:
Hardware Health sensors (I get this pretty much!)
Routing - routing table and ospf neighbours
CPU and Memory - fairly self explanatory!
Status and response time
Topology Layer 2
Topology Layer 3
I don't really want to monitor anything more than is necessary. If I could understand a bit more, especially in regard to Routing, EnergyWise and Topology I would be grateful.
- Status: Is the node up/down (can Orion ping it w/icmp or poll via SNMP)
I have a bit of trouble with this SNMP option here done NOT report that the device is up or down. You would think so but it does not. Recently I had several device that stop responding to and where not collecting data (because snmp stopped responding). You would think the devices would show as down but NO. Because they responded to ping they were up and active with no problems. This is a HUGE gotcha! Check THWACK post for SNMP not responding. I had to create an alert to trigger if there was no snmp update.
Ping is all that is used for up/down
Again HUGE gotcha!
EnergyWise was Cisco attempt to control power (POE) before VoIP phones but which the advent of VoIP phones using POE this feature became useless. Unless your switch/routers are setup for to use EnergyWise do not bother with it, as it is polling for nothing.
Is correct, from my understanding, with his Layer 2 and Layer 3 definitions.
In short do not select EnergyWise, it is very likely your are not using it.
