Is it possible to use Regex in Grafana Config

[MarcusCaepio]

Hi Carsten,
sorry that I have to open an Issue for this.
First, thanks for all the help, I am on a really good way right now. Everything looks shiny.
I am just struggeling with one situation.

For the service "disk: ...." I have 3 different check commands:

• disk for icinga hosts
• by_ssh for linux hosts
• by_wmi for windows hosts
  For each check_command, there are 2 kind of services: "disk:all partitions", which is my default service, spreaded by an template and "disk:XYZ" which appears, when sb. defines an dictionary (this also disables the all partition check) in an host config. I have a grafana panel called "disk" which already shows all three kinds of check_commands, depending on the host I choose. What I now need, is a way to use sth. like "disk:*" in the module config to lead the module to my default dashboard with the disk panel.

E.G.: In the module config I set the graph with the name "disk:all partitons" to my def. dashboard with the panel id, the Icingaweb preview shows the right graph for the service "disk:all partitions". But if I want the preview of "disk:/var/lib" the module leads to the "icinga-default" dashboard as long as I set "disk:/var/lib" in the module config.
As I don't want to set every single possible mountpoint, I need sth. like "disk:*", which always leads to my default dashboard with the disk panel id.
This regex would fit everything. is that anyhow possible?

Cheers,
Marcus

Hello @MarcusCaepio ,

iam sorry but thata would not be possible. Icingaweb2 uses Zendframework and there is no working solution to use regex to find a matching configuration in a ini file.

But you can use the custvarconfig option in your services/apply rules to tell the module which dashboard it should use. For example you have a graph configuration for your disks named my_disk_services then you can add to your service/apply rule this line and it will use the graph configuration you put into the custom variable no matter what service name/command name is used.

   vars.grafana_graph_config = "my_service_graphconfig"

The other option is to name your services with a space after "disk:" , then you would also need only 1 graph configuration for service names disk: * . It would match then all service names that start with "disk:"

Best regards,
Carsten
