Hi. I’m trying to understand what the dmi and rpm scripts in /opt/librenms-agent/agent-local do.
I run them and it does present information, but how are these used if I put the scripts into:
/usr/lib/check_mk/local
?
What would I expect on the GUI front end? would I need to configure anything on the front end to support the scripts?
Thanks.
The rpm script, assuming you’re running an RPM package distro, should create a new a new tab on your device called Pkgs.
The dmi script just collects a bit more overview info.
With:
I don’t think you need to configure anything as long as your agent is accessible and the unix-agent module was properly detected and enabled for your device.
Hi slashdoom. I really appreciate your speedy response.
Yes I simply moved them into place, and the next run of the poller populated the details and added the pkgs tab.
Very nice.
Thanks again.
Hi. Just one more query.
I was able to perform this on all machines except the LibreNMS server itself, since the server itself doesn’t run check_mk so couldn’t run the “dmi” script with it (or the rpm script since it’s running CentOS 7).
What do I need to do to get these two check_mk plugin working for the LibreNMS server itself?
Thanks.
Maybe I’m misunderstanding but all you should have to do is install the agent on your LibreNMS server.
https://docs.librenms.org/#Extensions/Agent-Setup/
Follow the systemd steps if it is a CentOS7 box. Then just copy the scripts to the agent directory like you did with the other servers.
Hi slashdoom.
For an endpoint, the https://docs.librenms.org/#Extensions/Agent-Setup/ instructions are valid, but for the LibreNMS server itself, it’s not as the LibreNMS server has it’s own tree under /opt/librenms.
To clarify, for an endpoint following the git clone we have:
[root@endpoint ~]# ll /opt/librenms-agent/

For the LibreNMS server, it’s different and doesn’t have check_mk_agent as shown:

So I can’t see how the git clone won’t clobber the /opt/librenms directory and possibly cause problems for the librenms install or future updates.
Should the instructions be updated to install the check_mk stuff into a directory other than /opt/librenms ?
Thanks.
It should be a different directory already. /opt/librenms vs. /opt/librenms-agent, right?
Hi slashdoom. Yes you are correct, I overlooked that.
Being in different directories, I went through and followed the process and all worked.
Really happy, good software 
Thanks again.
