Nagios Support Forum

Hi,

I was monitoring a esx using check_esx3.pl plugin for few days. it was working fine. some 7 days back some user permission was changed in ESX. so i was getting unknown error in both command line and in UI. But yesterday, the user permission was provided and i am able to fetch the output in command line. But the output is not getting updated in nagios core UI. (Still displaying the old output in status information). I have attached the screenshots of the same. Please help me to make the UI update.

Thanks ,

Hi,

I have tried to fix the issue. Meanwhile i found the checks for this host and service are scheduled but not really being executed . I could not find the logs related to this host and service of that host. Only for this esx server i am facing this issue.. Other monitoring are working fine. Only for one host the checks are not happening. Please help me out in fixing this..

I have restarted nagios service as well.. but still the checks are not happening only for this host.

Thanks,
Sattanathan.S

Could you post the output of:

Hi Abrist,

I found these logs before 10 days and there is no log being written now. Attached the same log for your reference.

I have done tail -f nagios.log | grep mmkndhaesx5 for 3 hours but i could not see even a single log.

This means the checks for this service is not really being happen i think. But other host and service checks are happening properly. Checks are not being executed only for this host. Please help me in finding a solution for this.

Thanks,
Sattanathan.S

Verify the Nagios configuration and report back:

Hi Abrist,

I am verifying the configuration everytime before i restart the nagois service. There is no error or warning message.

Today i found some logs for this esx at exactly midnight(Jan 15 00:00:00). Everyday at the midnight there is a log for this esx with the incorrect output and same is being displayed in the UI. After the check at midnight there is no further checks happening.(No logs for the ESX).

I have left a session for the whole day with the command(tail -f nagios.log | grep mmkndhaesx5) being executed from which i found the check has happened at midnight.

Please suggest a solution to overcome this ghost.

Thanks,
Sattanathan.S

Could you post those logs concerning ESX that happen at midnight?

Hi ,

This is odd behavior. Lets make sure you don't have more than one nagios process running.

This was the first step i did when i looked at this error. Restarted nagios service several times and also verified only one instance of Nagios is running. But still facing the issue. Please let me know if there are any other thing to be checked.

Thanks..
