Data list in apply rule

Icinga Web Modules Icinga Director
1

Hello,

(Please find below the module’s versions of my setup)

Using Director, I’ve created a data list (containing hosts names, but that could contain really any random data some day), and in a service apply rule, I’m trying to use it this way (pseudo code, but you get the idea) :

assign where host.name not in $my_custom_data_list$

I have absolutely no idea how to use Director to make it use the data list, neither which would be the correct syntax (so probably not with these funny dollars).
At present, obviously, my apply rule does not understand that it has to look into this data list.

Is there a way to make it use the globally defined data list?

Thank you

Nicolas

The director uses fields to expose variables and lists in variables in the webinterface.

Most likely you would add the field that utilizes the list in a template.

Hello @rivad ,

Though I’ve succeed using fields and exposing them in other contexts, here in this case, I’m stuck : I can add a field that is using the data list (and possibly add a category), but then, which template should I add this field to?

My service apply rule imports a service template, so I added the field to this service template.
In the apply rules webgui, it does not seem to allow me to use the data list in the “contains” or “in” fields…

Maybe you need to apply it to the host template as I do in the datalist of tags that I use to apply service-sets.

May I ask you a pointer to read what you wrote about list of tags, please?

i use a field called tags that contains a datalist and service-sets use the contains rule to check if the tag is in the custom variable.

This was recommended to me by the Linuxfabrik via there monitoring plugins.

Hi @rivad ,

Coming back to this issue, I finally understood what was missing in my non-understanding : I was trying to compare a variable to another variable, using Director.
I found no mean to do this, as long I was using Director.
When I switched to writing a /etc/icinga2/conf.d/custom.conf file, I was able to do that :

const EXCLUDE_LIST = [ "host1", "host2" ]

apply Service "svcaplyrul1" {
    import "somesvc"

    assign where host.vars.something01 == "true" !( host.name in EXCLUDE_LIST )

    import DirectorOverrideTemplate
}

Now this rule is written, I can only change the content of EXCLUDE_LIST, maybe placing it in another specific file.
Using the Director web GUI, it was not possible to reach this : every try ended up with Director converting the left or right part of the comparison into a string (adding double quotes).

So I’m a bit sad not to be able to keep a 100% web setup, but sometimes, one has to keep going.

Yes, sadly the only place where you can use the DSL in the director is in check commands.
