Hello
@ciscosucks123,
I'd like to review the logs in the system profile and take a look at the size of the server and monitoring setup. Additionally, please post the output of the following query to check the database table sizes. Thanks.
Code: Select all
echo "SELECT table_name AS 'Table', round(((data_length + index_length) / 1024 / 1024), 2) 'Size in MB' FROM information_schema.TABLES WHERE table_schema IN ('nagios', 'nagiosql', 'nagiosxi');" | mysql -h 127.0.0.1 -uroot -pnagiosxi --table
Login to the Nagios XI GUI using a web browser.
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button
Save the profile.zip file and share this in a private message and then
reply to this post to bring it up in the queue.

I talked to the dev about this and he said they should be ignored because the calculation is wrong.
