HTTP CRITICAL on Nagios
I've been running nagios for about last three month, but recently from last 2-3 days a problem started appearing with one of my service. As i check everything on apache working fine. I'm getting following message:
"CRITICAL - Socket timeout after 10 seconds"
i checked it through command line it's giving below error :
./check_http -I IPofServer -p 80
No route to host
HTTP CRITICAL - Unable to open TCP socket
can you please tell me what's the problem & what should we do to correct the proble
No route to host means there's some network problem preventing connection.
Make sure you can actually ping / telnet to the server in question from the Nagios collector.
telnet ipofserver 80
If that is not successfully, then you need to check networking and routes.
If it is successful, then you might have some Nagios problem.
