When selecting different sections for the Admin Console, it takes a long time to load (over 30 seconds delay when viewing the Hostgroup Summary and Apply Configurations).

Already tried updating my.cnf with the following values:
innodb_thread_concurrency=0
innodb_read_io_threads=64
innodb_write_io_threads=64

Runs a little faster, but still takes a long time to load the hostgroup summary.

Hi @Phisith,

If you haven't done so already, please follow the steps in the guide below to optimize the PHP settings on this system. That should help improve GUI performance.

Nagios XI - Optimizing The PHP Settings File

If the database is causing performance issues, please upload my.cnf file along with a fresh system profile and we'll review the logs for any issues.

To send us your system profile.
Login to the Nagios XI GUI using a web browser.
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button

Lastly, please post the output of the following query to check the table sizes. Thanks, Benjamin

Followed the suggested PHP.INI settings ... don't see any improvements.

Attached are the table size and system profile. Let me know if you need anything else. Thanks, -Phisih

and the table sizes query output

Hi,

Starting 5.7.x, we implemented a new backend database application, and have been making continuous updates to this program, I would recommend taking a full backup and upgrading to 5.8.2.

You're just over 20k host and service checks, did you ever experience issues with the kernel message queues on this system?

The log entries table is pretty large, I would recommend truncating that. You'll find instructions for this on page 5 of the following guide.

Additionally, I would follow the guide below to adjust the performance settings in the Admin area by increasing the multiplier on the refresh rate for the dashlets.

Then optimize the database settings.

Let me know if the performance improves after making those changes.
