Polling every 5 minutes is the globally accepted industry standard.
You need to think very, very hard about changing it.

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! Adam.

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.

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.
