OP5 Monitor - Report - "Request-URI Too Large"

In some situations, for example while trying to modify the settings for a report, you may get an error stating:

Request-URI Too Large
The requested URL's length exceeds the capacity limit for this server

This issue can likely be resolved by adding some custom configuration for the Apache web server.

Do the following:

• Create a new file as root:

/etc/httpd/conf.d/op5-request-size.conf

• File should contain:

LimitRequestFieldSize 104857600
LimitRequestLine 32767000

• Save the file and restart httpd:

# systemctl restart httpd

See if you still get the error. To revert the change in case of issues, simply delete the file previously created and restart httpd again.
