Feature to force contact_groups append instead of overwrite

[Tontonitch]

Hi,

I needed to have some contact_group inheritances between host-templates / service-templates, which don't overwrite the contact_group defined on the host/service.

For that, I've written a patch that add an option in the nconf.php file:
a new variable FORCE_CONTACTGROUPS_APPEND can be set to globally change the way that contactgroups are added when inherited

• 0: overwrite existing contact groups. this is the default and actual behaviour
• 1: append to existing contact groups (add the '+' prefix)

Note that currently the default behaviour changes for host and service depending on the SUPERADMIN_GROUPS definition (if prefixed by a '+' or not).

So, when the FORCE_CONTACTGROUPS_APPEND option is set to 1, a character '+' will be added in front of the contact_groups lists when writing the following classes to nagios cfg files:

• host
• service
• advanced-service
• host-template
• service-template

For exemple, it is now possible to have multiple templates on the same host, and contact_groups on that host will be the sum of every contact_groups (every linked templates + host).

Attached the patch:

nconf-1.3.0-0_feature_force_contactgroups_append.patch.zip

That would be great to have in future release of NConf something more flexible.
For exemple, a radio button below every contact_group selector. Something similar to what is already implemented when multimodifying contactgroups of some services.

• selecting 'overwrite' would trigger the actual behaviour.
• selecting 'append' would add a '+' to the contactgroup list, which indicates that a '+' character will be added in front of the contact_group list when written in the nagios cfg file.

BR,
Yannick

Hi,
0. Backup your nconf installation (ex: tar cfz nconf_install.tar.gz /usr/local/nconf or whatever you used)
1. Copy the patch file to this directory
2. Test the patch application: cd <nconf path>; patch --verbose --dry-run -p0 < nconf-1.3.0-0_feature_force_contactgroups_append.patch
3. If no problem reported, apply the patch: patch --verbose -p0 < nconf-1.3.0-0_feature_force_contactgroups_append.patch
