Status Polling

jedski

How many minutes or seconds does it take for NPM Polling Engine to check the status of the nodes/interfaces/volumes?

How many minutes or seconds does it take for NPM Polling Engine to consider the node/interface/volume in a WARNING state?

How many minutes or seconds does it take for NPM Polling Engine to consider the node/interface/volume in a DOWN state from WARNING state?

Where can this be verified in the NPM Settings? Please advise.

 

Thanks,

NPM default polling times:

ICMP polling for status:
------------------------
Volumes = 120 sec
Interfaces = 120 sec
Nodes = 120 sec
 
SNMP polling for statistics:
----------------------------
Volumes = 15 min
Interfaces = 9 min
Nodes = 10 min

When a node fails to respond to a ping it is put into WARNING status.
It is then 'fast polled' which means it is polled once every 10 seconds for the fast polling interval.
Fast polling default interval = 120 seconds

If a node fails to respond during the fast polling interval it is put into DOWN status.

These values can be changed in NPM in the Web Console by going to the Polling Settings on the Admin page.

Polling Intervals is for the ICMP status polling.
Polling Statistics Intervals is for the SNMP statistics polling
Node Warning Level (near the botton of the page) is the fast polling interval.
