Nagios stops sending alerts automatically

Hello Team,
My Nagios core suddenly stops sending alerts after 4-7 days.
After restarting it starts sending alerts that were in the queue, I don't understand what the issue is.
Also, I checked free space and saw 4 GB free space on the Nagios server.
Thanks for the help.

Hello @mandar18,
To untangle this technical trouble, you should likely look at your logs located in
/usr/local/nagios/var/nagios.log.
You can also investigate this anomaly by examining your Nagios config and queue.
The following command committed in the CLI will verify whether your configuration is valid:
Code: Select all
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
This will find if the failure is from flaws from your configuration.
If your messages are mounting, you might find them in the mail queue here:
/var/spool/mail/nagios.
If you cannot find the fault fomenting this failure through the logs, you can file an issue here:
https://github.com/NagiosEnterprises/nagioscore/issues.
If you'd like me to file one for you, post here requesting it and I shall file it for you.
Please post a response if the problem persists and we'll be happy to help.

Hello bbahn,
Still, the issue is not resolved, I did the following command "/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg" to check for errors but there are no errors in configuration.
Can you please file an issue for me on
https://github.com/NagiosEnterprises/nagioscore/issues.

Hello @mandar18,
It seems there are already some issues relating to auto rescheduling indefinitely delaying checks:
https://github.com/NagiosEnterprises/na ... issues/947
and
https://github.com/NagiosEnterprises/na ... issues/893.
Do you have auto-rescheduling enabled? If so, I'll add a comment pointing to this thread on those issues. If not, I'll file a new issue for you.

Hi @mandar18
I checked and there are absolutely no errors in the configuration. Is there any solution to this problem?

@employerflee,
As I asked mandar18, do you have auto-rescheduling enabled? There are known and filed bugs that cause auto-rescheduling to infinitely delay checks.
