Getting a random crash, some log files attached

We're getting what seems to be a random crash on our NagiosXI server. This seems to be the start of the problem.

It is seemingly down until a restart of the monitoring process is done.

Any ideas?

If you PM me a system profile I can diagnose further. Get one by going to Admin (top menu) => System Profile (in the left menu), then clicking the blue button.

If you're unable to generate the the profile through the web interface, please try generating it from the command line by running these commands as root:

Code: Select all

rm -rf /usr/local/nagiosxi/var/components/profile*
/usr/local/nagiosxi/scripts/components/getprofile.sh SUPPORT
Then send me the resulting /usr/local/nagiosxi/var/components/profile.zip file.
If the profile script fails, please include the ENTIRE output.

In `/etc/my.cnf.d/nagios.cnf`, create a file with the following lines:

Code: Select all

[mysqld]
innodb_log_buffer_size = 32M
innodb_buffer_pool_size = 1G
innodb_log_file_size = 256M
max_allowed_packet = 67108864
Then run the following commands as root:

Code: Select all

/usr/local/nagiosxi/scripts/manage_services.sh stop nagios
/usr/local/nagiosxi/scripts/manage_services.sh stop mysqld
rm /var/lib/mysql/ib_logfile0
rm /var/lib/mysql/ib_logfile1
/usr/local/nagiosxi/scripts/manage_services.sh restart mysqld
/usr/local/nagiosxi/scripts/manage_services.sh restart nagios

I guess I was too quick to reply after receiving your profile.

Did you try my suggestion above? Did that fix your issue?

Sorry to hear that, and hope you are feeling much better.

Let us know how it goes. Dan is out on vacation, please send any private message to my account. Thanks, Benjamin

Seems to be running better, but now my backups are failing.

Code: Select all

Last output from the system: Error backing up MySQL database 'nagios' - check the password in this script!

Hi,

The last profile sent had crashed tables in the database log, try running the repair script below as root from the CLI.

Code: Select all

/usr/local/nagiosxi/scripts/repair_databases.sh
Then test run another backup job. If that's not the issue, verify the correct passwords using the guide below.
