Let me post here one more real case (production). Not sure I need to report a new ZBX.

When attempting to link templates to another template.
Open one template, on "Linked templates" tab click Select button and you will see the "Request-URI Too Long" Apaches's error page.

In this real case URL is ~26K characters long.
See documentation for the param https://httpd.apache.org/docs/2.4/mod/core.html, there is an important note where the the param should be set.

Depending on distro and Apache configuration, as a workaround, need to add a line:

LimitRequestLine 30000

to one of these locations:

  • on RHEL/CentOS (comes withOUT virtual hosts enabled, if so) to /etc/httpd/conf/httpd.conf
  • on Debian/Ubuntu (comes with virtual hosts enabled) to /etc/apache2/sites-enabled/000-default.conf inside section <VirtualHost *:80>

The button Select constructs very long URL like:

&excludeids[]=10186&excludeids[]=10203&excludeids[]=10225&excludeids[]=10237

where are listed IDs of templates:

  • current template itself
  • already linked templates
  • templates linked to

The last point causes the URL to be so big.
Good example is build-in template "Template Module Generic SNMPv2", which causes 642 chars long link.
