Thanks for the quick reply. Polling at every 5 minutes is pretty useless isn’t it? How complex is that to modify the rrd ?

Sujith?

Polling at anything other than 5 minute intervals will have no benefit. Since the rrd files are hardcoded to 5 minute at creation time.

This can be modified, but is more complex than just changing the poller frequency!

Hello Sujith,

 

When you set an alert you can set the number of polling runs before the alert actually fires.

 

Under Alert Checkers set the “Alert Delay" for the checker to 3 or 4 and see if the results improve.

 

If you are polling every minute you might start a polling run while the previous polling run is still happening. I would up this from 1 minute to about 2 or 3 minutes at least. Would be good to hear other comments on the fast polling time.

Hi Team,

 

How to avoid false device down alerts? I think it just single ping and small network glitch on observium server to monitor device  alerts are device down. I am polling every minutes though.  Is there any way to let observium at least poll second time and alert device is down?

 

Thanks,

Sujith.
