Slow dashboard loading ....

Post by vishfx »

Hi Nagios Team,

Am using Nagios Fusion 4.1.6

I have a dashboard with :
Tactitcal Summary
Service Group status
5 Performance graphs.

However, I see that the dashboards take a lot of time ( sometime 30 secs ) to load.
Below is a sample screenshot :

How can we speed the loading time ?

Kindly advise.

Regards,
Vish.

Hello Vish,

Please send me the output of this command so that we can see how large the tables are getting:

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 = 'fusion';" | mysql -ufusion -pfusion --table
Please run the dashboard again and then send me the output of these commands once you start it:

Code: Select all

top -n5
tail -F /var/log/httpd/error_log /var/log/httpd/ssl_error_log
Please attach your /etc/php.ini as well.


Thank you

Hi @vishfx,

Thanks for sending over those files. One question we have is how many users are usually logged in at the same time?

Please increase the following values in php.ini:

Code: Select all

max_execution_time = 120
max_input_time = 120
memory_limit = 1G
Then restart Apache:

Code: Select all

systemctl restart httpd
Let us know if this resolve the issue.

Hi Sean,

It seems to have marginally improved.
Can this be improved further ?

At present, there are not more than 5 users logged in.

Regards,
Vish.

Hi @vishfx,

We've recently made updates to Fusion to limit the polling of data to only users currently logged in. This will help reduce the load on the Fusion Server and improve performance.

We can either provide instructions for patching the system or Sean can reach to you a setup a remote session. Please let us know which would work best for you.

Thank you.
