CMK version: 2.2.0p14 raw
OS version: Debian Bulleyes
** CheckMK plugin: tribe-29-checkmk-datasource @ 3.2.2**
** Grafana version: v10.4.2
Error message: Bad Request These fields have problems: host_name
I followed Integrating Checkmk in Grafana to use variables
The menu allowing to multi-select hosts is present.
If a select one single host, graph is working fine.
But I select several hosts, I get the error above in Grafana.
What am I doing wrong ?
you can use this plugin to do it
You are not doing anything wrong. This is a limitation of the plugin.
I’ve already explained this here:
English version: There is a workaround to accomplish that with the enterprise editions of checkmk: instead of using the host filter, you can use the regex filter and enter the following variable: ${variable_name:regex} this will combine multiple host names into one valid regex expression matching all the hostnames selected in the variable menu.
