I have installed nagios on a redhat server. I have added another server from the same network to the hosts/services/… files in order to monitor it as a test. I’m using only a check_ping command right now to see if I got the configuration correct. I’ve shut down the test server (the one that doesn’t run nagios) to test if my configurations were correct. Nagios realized that the server went down immediately, but when I powered that test server up again it takes about 20 minutes or so for it to recognize thats back up again. I put the normal_check_interval = 1 so it would recheck the status within a minute, but unfortunately it takes a lot longer than that. Is there other places that I should modify time intervals in in order to get faster responses (which is never the case when something goes down, but is the case when something goes up again).
Thank you very much.
