New to CheckMK, a few questions

Hi @cyr0nk0r

Welcome to the forum!
Some of your questions have already been answered, let me see if I can plug the remaining holes.

@cyr0nk0r

• Even the enterprise version is self hosted correct?

Yes. Currently all Checkmk editions are self-hosted.

Does CheckMK integrate with Aruba InstantOn devices? Check Plug-Ins Catalog the integration doesn’t mention anything about the cloud hosted wireless controllers that the InstantOn products use.

You mentioned that you looked in the Plugins catalog (great!). Doesn’t look like there’s anything out of the box there. Here is what we have for Aruba: https://checkmk.com/integrations?distributions%5B%5D=check_mk&distributions%5B%5D=check_mk_cloud&tags=aruba
If that doesn’t suffice, building your own Check plugin is very doable, though.

I’ve noticed that all of the bandwidth graphs report IN bandwidth as a positive number, and the OUT bandwidth as a negative number. Is there a way to stack both of these IN and OUT as positive numbers and lay them over each other? I don’t like having IN bandwidth above the 0 line, and OUT bandwidth below it.

Does CheckMK log windows eventlog data? Or other log data from devices? Like firewall logs, etc. Or are the events inside CheckMK just going to be alert events based on CPU, disk, network utilization, etc.?

You can monitor the Windows eventlog (or any other log, for that matter) using the Event Console. Read more here: The Event Console - Processing logs and SNMP traps

Does CheckMK support native integration with SonicWall firewalls? I found this Checkmk Exchange but not sure if anyone is using it successfully.

There’s no out of the box plugin provided by us. The one from the Exchange looks like a good starting point. The good thing is, it is based on Checkmk 2.0, so it will already be written in Python3 and (maybe) using the new Check API. Definitely worth a try.

I’m a big dashboard person. I want each host to have an easy to navigate dashboard when you look at all the services for that host. When I’m looking at the CheckMK live demo : <cant include more than 2 links for some reason> I’m seeing some strange behavior on how you view hosts.

This “strange behavior” is due to the fact that views and dashboards are somewhat different animals. The easiest way is to this is probably to simply bookmark the “single host” dashboard (using the bookmark snapin) and then use the filters to filter to host you want to see.
