CheckMK - Grafana - Process Discovery

[KSJakobsen]

Hi,

I have been using CheckMK and the corresponding CheckMK-Grafana Plugin for visualizing a sort of Network/Host Monitoring. And now i ran into a problem.

I’ve added the checks for some processes on our Windows Server 2019 machines. While the processes are running everything works as expected and i can visualize the Check in Grafana. (Green for process is running). Once the process is not running, i would assume that the check would go red, since there is no process running but grafana throws an exception that it “cannot read property “meta” of undefined”.

i tried the enforced service and it is working more consistently, but there is still 1 problem.

If the process is running and you select the metric within Grafana, the number of processes is at position 5 or so within the possible metrics. If the process is not running there is only 1 metric left and so Grafana can not find the 5th metric within the service and and therefore throws another exception. “e is undefined”.

We’re running on CheckMK-Raw-2.0.0p7.

Kind Regards
Kai Jakobsen

I have also opened up a troubleshooting post in the CheckMK Forum.

Can you still reproduce this issue with Checkmk >= 2.1.0 and the current stable release of this plugin?
