omdclient 1.3.3.post4

omdclient check_mk + WATO/OMD interface

omdclient

omdclient provides a suite of tools to interact with the APIs associated with the check_mk/Open Monitoring Distribution tool suite

WATO APIs

WATO is used to create, remove, and modify entries within the OMD user suite. This is documented at:

http://mathias-kettner.com/checkmk_wato_webapi.html

omd-host-crud

Creates/Reads/Updates/Deletes entries from an existing monitoring interface.

omd-activate

Activates changes made by the API user.

omd-puppet-enc

Provides a linkage between a puppet External Node Classifier (ENC) and a monitoring instance. In essence, we want to add hosts to monitoring when a host is added to puppet; remove the host from monitoring when the host is removed from puppet; and re-tag the host when its role changes.

https://docs.puppetlabs.com/guides/external_nodes.html

Multisite/Nagios

https://mathias-kettner.de/checkmk_multisite_automation.html

omd-nagios-ack

Acknowledges host/service alerts from the command-line.

omd-nagios-downtime

Schedules host/service downtimes from the command-line.

omd-nagios-report

Prints a human-readable report on current host and service alerts.

How To Use

/etc/omdclient/config.yaml

You'll have to populate this file on your own:

server: 'xxxxxx.example'
site: 'xxxxxx'
user: 'xxxx-api'
apikey: 'xxxxxx'

If you set the 'OMDCONFIG' environment variable you can point at different configs, e.g.:

OMDCONFIG=/tmp/myconfig.yaml omd-activate

Configuration of 'expanded views'

The report scripts depend on 'expanded view' versions of the hostproblems and svcproblems views, which add comments. In order to add these, you generally have to:

1. Edit view hostproblems - it's a default view, so you'll go to 'clone'.
   • Change the name from hostproblems to hostproblems_expanded.
   • Scroll down to the list of columns, and add one more: Host Comments.
   • (newer versions) set to 'public' and 'hidden'.
   • Save.
2. Edit the view svcproblems and created svcproblems_expanded, same as above but with the column Service Comments.

In newer versions of check_mk, you may also need to make these views Public (check Visibility / Make this view available for other users / Publish to all users). Also, the hostproblems base view may have changed: I have for hostproblems_expanded:

1. Hostname
2. Host icons
3. Host state
4. Output of host check plugin
5. Number of services in state OK
6. Number of services in state WARN
7. Number of services in state UNKNOWN
8. Number of services in state CRIT
9. Number of services in state PENDING
10. The age of the current host state
11. Host comments

How To Build

There is a Makefile.bak and a *.spec file that mirrors my local build process for RPMs, if this matches your requirements; just run make -f Makefile.bak build-nomock.

Otherwise, you may want to just follow the general instructions in *.spec. Scripts from usr/bin/* go into your path; create /etc/omdclient/config.yaml as described above; make man pages with pod2man if you're ambitious; and run python setup.py install to install the python library.

Debian

make -f Makefile.deb build

That should build a full .deb package.
