Hi Team,

The errors that you are describing are usually caused by intermittent network connection losses between the Nagios server and the remote server that is being monitored.
The remote server may be up all of the time but if the Nagios server cannot connect to the remote server, the checks will generate the timeout message or a 255 message.

Can you describe how the network is setup between the sites?

Lets try this command to ping one of the remote server continuously and output the data to a file.
Replace hostname with one of the servers.

Code: Select all

 ping hostname | perl -nle 'print scalar(localtime), " ", $_' | tee -a ping.txt

Then, if you get the 255 error or a timeout error, stop the ping and check the ping.txt file to see if there was a connection issue between the servers.
