Last night, one of my server (server A) was down and when it was already up, it was still red (HOST STATUS DOWN) even though the service ssh is now ok in that server. When i checked the status.log, it shows that :
HOST;SERVERA;DOWN;1131262985;1131206895;0;950927;0;0;1131206895;1;1;1;1;1;0;0.00;0;1;1;CRITICAL - Plugin timed out after 10 seconds
SERVICE;SERVERA;SSH;OK;1/5;HARD;1131262981;1131263161;ACTIVE;1;1;1;1131207025;0;OK;950928;0;0;129;0;0;1;0;0;1;0;0.00;0;1;1;1
;SSH OK - OpenSSH_3.9p1 (protocol 1.99)
In my webinterface, service status (ssh) is ok but host status (serverA) is down. I received an email saying it was down last night but after 1 hour, it goes back to normal but since then host status never change only the service status (ssh) is ok. i checked /var/spool/mail/nagios and it is 0 bytes.
i also tried to do pre-flight check and it found no error
Checking global event handlers…
Checking obsessive compulsive service processor command…
Checking misc settings…
Total Warnings: 0
Total Errors: 0
Things look okay - No serious problems were detected during the pre-flight check
I hope someone can help me with this problem.
