my Nagios core 4.3.4 is crazy

[mesobranlaspalabras]

Hello,

Sometimes Nagios sends us false alarms about the previous configuration. For example, I changed the ssh port in two servers, and changed the configuration in my nagios, but sometimes it appears alarms in the ssh service

I deleted nagios.cache and nagios.precache and I restart the service, but the problem persists.

Has anyone suffered the same problem?

Thanks in advance,

Sometimes this can happen if you have multiple Core processes running, often the result of an improper shutdown. Please run the following commands and post the output:

ps -ef | grep bin/nagios

Good morning,

Thanks for replying

I executed the command and this is the results

Definitely multiple competing processes. Please run the following and post the output:

Code: Select all

service nagios stop
killall nagios
service nagios start

We have a KB article that goes over one of the issues that multiple processes can cause: https://support.nagios.com/kb/article/n ... ts-27.html

Particularly the "Possible Causes" section shows what a good output should look like.

Hi,

Thank you very much for the help. Now Nagios works correctly.
