Nagios hostgroup

Chef Infra (archive)
1

Drawing a blank here.

Typically with Nagios data bags, you would create the services and use the
’role’ as the hostgroup; would it be possible to apply multiple hostgroup
to a particular service?

I have storage servers that need to have C:, D:, and E:\ Drive and use
role ‘Storage’ to monitor all 3 drives; however, I have some old school
storage servers that use C:\ H:\ I:. Would I be able to append 'storage’
and ‘old_storage’ to the hostgroup name?

The Chef role to Nagios host group role assignment is a 1 to 1 relationship. You could use the search based host groups to add another host group though. You can search out attributes or chef roles and define another host group that includes a specific set of monitors. There's an example of the syntax for that in the Readme and the examples directory.

What Tim said. If you do a search based hostgroup the query would be like
"role:storage OR role:oldstorage". You can also specify multiple hostgroups
on the service by doing something like:

{
...

"hostgroup_name": "storage,oldstorage"
}

Remember that Nagios supports things like wildcard matching, regexes, and
exclusions via the ! operator. Combining these with databags, especially
once COOK-3781 is merged in, will give you a lot of flexibility.

That was exactly what I was looking for:

{
...
"hostgroup_name": "storage,oldstorage"
}

I am assuming this, depending on which role you pass to a node, would use this server. I wasn't sure if the above would be accepted.

What you probably want is to define two NSClient++/NRPE checks, one on
storage, and one on oldstorage, varying on the drive letters (but named the
same, which you can do in a recipe). Then your service definition would
apply to both hostgroups and the variation will be handled by the
underlying nodes themselves.
