The following indicates how NMIS will behave when provided with various configuration options, this is specifically concerned with active, ping and collect.
| Polling Description | active | ping | collect | plugins | services |
|---|---|---|---|---|---|
| Regular node polling, the node will be ICMP polled and will have SNMP and WMI (if credentials configured) data collected | true | true | true | Will be run | will be polled if configured |
| SNMP Only Node, the not will have SNMP collected but ICMP polling will not be performed. | true | false | true | Will be run | will be polled if configured |
| Ping Only Node, the node will only be polled using ICMP. | true | true | false | Will be run | will be polled if configured |
| Service Only Node, the node will only have services collected if they are configured. | true | false | false | Will be run | will be polled if configured |
| Node is NOT active and NMIS will mostly ignore the node. | false | N/A | N/A | N/A | N/A |

NMIS8 Plugin Operation
NMIS8 Plugins will run for any node which is active, but logically a plugin needs to be able to know what type of node it is operating on. Plugins will generally include early in the code a statement to look for a specific model type and if the model is of a type interesting to it, it will perform its duties, otherwise it will skip (return nothing).
