Nagios Support Forum

Good morning Nagios team,

We have had a few issues with our Nagios instance where we had to reboot the server. This morning around 1am, our Nagios instance's services stopped and this has happened a few times over the last few months. Would it be possible for someone to take a look at the logs or perform some sort of maintenance to check the health of our Nagios instance?

Feel free to PM me a profile(Admin > System Config > System Profile > Download System Profile) and I'd be glad to take a look at things. Note that the profile _can_ be too large to send and this is usually because it contains another zip file within containing the configuration. Feel free to remove this if needed. The filename is a .tar.gz and begins with a Unix epoch time. For example:1524250995.tar.gz.

The profile showed corruption of the database which can be caused by performance issues on the machine. Follow https://assets.nagios.com/downloads/nag ... ios-XI.pdf to setup a ramdisk as well as applying other tweaks to the system to improve performance.

What did you see that indicated database corruption?

The drive space no longer appears to be a problem and there repair of a table, but I would still run the repair script to make sure everything else is good.
