Has anyone written a script to gather a server inventory out of Check_Mk using Livestatus then formatting the output so that it can be used by Ansible dynamic inventory?
Why you want to use Livestatus. Better use the WebAPI to get the inventory data as JSON.
Sure, that works tooā¦ Livestatus will also let you output in JSON. What I was hoping is that someone already wrote something that created JSON that Ansible expects (See Inventory Script Conventions here: https://docs.ansible.com/ansible/latest/dev_guide/developing_inventory.html#inventory-script-conventions). Iām not very good with JSON but I will attempt to fumble through it if nobody else has.
With the WebAPI, I donāt see an example of how to return a list of all servers. All of the examples are requesting info for a specific host or hosts. How do I return info for all servers or all servers matching some filter (wildcard, matching tag, etc)?
Hi,
to get all host for the inventory request per host, you can use get_all_host from the WebAPI.
Cheers,

Yes, exactly like thisā¦ but my ansible did not seem to come with it? And Iām a github newbie so not having any luck finding the actual script ācontrib/omd.pyā.
Edit: Sorry this probably isnāt clearā¦ towards the bottom of the page you link, it linked to this: https://github.com/ansible/ansible/pull/11870 which seems really promisingā¦ but againā¦ my lack of github skills is getting in the way.
Replying to myselfā¦ I now see the notes that the OMD specific one was abandoned in favor of this one you linked toā¦ nagios_livestatus.py. Iām trying it out, but unfortunately it does not support encrypted livestatus which Iām usingā¦ If anyone better than me with Python wants to offer suggestions for adding encryption support, that would be great.
From the monitor host itself, so you can just tie directly to the livestatus socket (no SSL, etc), assuming a Linux with nc (netcat):
echo -e 'GET hosts\nColumns: name\nOutputFormat: json\n' | nc -U /opt/omd/sites/monit
or/tmp/run/live
Optionally, you can pretty print that JSON by piping through python -mjson.tool
Edit: the name of my site is āmonitorā in the above path to the āliveā socket.

Assuming you have an āautomationā user setup on your cmk and secret, something like this could work:
curl -s "https://your-ssl-hostname.example.com/monitor/check_mk/webapi.py?action
=get_all_hosts&_username=automation&_secret=my-very-long-secret&request_format=pytho
n&output_format=json"
And again, you can pretty print that to easily see how that looks by piping through python -mjson.tool
Hi @lance
I wanted to ask if you have any progress in your tries? If not I would try to create something with the webapi way.
@marass, I have not yetā¦ I have sort of put this to the back burner for the past month. I need to start investigating it again soon.
@lance so I have now a working PoC via WebAPI. I will push it on github if it has a structure that you can customize it.
Sounds great! Can you tell me where to find it on github?
Are you able to share a link to your github?
Iāve been using the omd.py for a few years now, but I added some functionality to list all the hostgroups and their members- which is really helpful with some of my playbooks.
I havenāt seen anything in the web API that can help with this. get_all_hostgroups just returns the hostgroup names.
Iāve created a simple inventory script based on Ravi Bhureās omd.py that supports multisite and ssl
The nagios-livestatus.py wouldnāt run in my environment, and some of the functionality I needed I had already added to omd.py. I also eschewed the check-mk web api because it is missing some critical functionality that I require.
The repo is here- GitHub - wezelboy/simple-ansible-inventory-from-check-mk: Provides dynamic inventory host info from check-mk to ansible.
