Which version of XI are you on and what OS?

Is your database running? Run this command to show us which db.

Code: Select all

awk '/"nagiosxi" => array\(/{getline;print}' /usr/local/nagiosxi/html/config.inc.php

Can you show us your db logs?

Code: Select all

tail -50 /var/log/mysqld.log

Or if you have mariadb

Code: Select all

tail -50 /var/log/mariadb.log

Hi @dwasswa and @kwang,
Thanks for your replies.
You guys are right. We checked the log and found disc space issue, as below. This is now resolved.

Thanks again.
