Check if the device can accept ping from IP observium source address. Check if there is some firewall rules that drop the ping after a while

Umm. Observium only pings every 5 minutes - at the start of every poll.

I don't see how that can be the case all the time when you can in the former mails observium saying the server is offline but you also see that i can clearly ping the server from observium.

in that specific scenario the server should have recovered since ping was responsive

Emne: Re: [Observium] im seeing device down but they are not

This seems to suggest that the servers are frequently not responding to
ping.

Probably caused by either poor connectivity or some form of
rate-limiting imposed by an in-path firewall or similar.

Hi,

  Yes, you have not shown why Observium thinks the device is down, only
that it pings x seconds or minutes after the alert is fired. Please
provide the device's last event logs when it's being considered down.

over the last few days i have starting seen alert mails with
device down.. but its not down.. and there is no recover..

anyone got a suggestion why that could be?

assume to see recover mail aswell?
