Icinga2 REST API variable synchronization with Icinga Director.

[haytxy]

Expected Behavior

Icinga Director should be able to update a variable object if the object has a null value and the value is already provided by Icinga Director for example in Service Template or Service Set.

Current Behavior

If previously the value for the variable object was given using Icinga2 REST API and we want to overwrite this value with the help of the Icinga Director, it is impossible.

Steps to Reproduce (for bugs)

With the help of Icinga2 REST API, I passed the value "13" for the postgres_critical variable. Which resulted in overwriting the value that I had configured in "Icinga Service Sets"

curl -k -s -S -i -u user:pass -H 'Accept: application/json' -X POST 'https://localhost:5665/v1/objects/services/host-object!service-object -d '{ "attrs": { "vars.postgres_critical" : "13" }}'

I would like to reverse the process. However, when I'm using the Icinga2 REST API to overite postgres_critical and put a null value for this variable. curl -k -s -S -i -u user:pass -H 'Accept: application/json' -X POST 'https://localhost:5665/v1/objects/services/host-object!service-object -d '{ "attrs": { "vars.postgres_critical" : null }}'

It doesn't change anything. I am unable to get back the value specified in Icinga Director. The variable postgres_critical takes the value null Inspect >> Executed Command >> '-c' '' and does not retrieve the value previously configured in Icinga Director.

I can only see the Icinga Director value under original_attributes.

How to use a value defined in Icinga Director if previously this value was put under variable by Icinga2 REST API?

Hi, if you want to restore the previous value of that variable you've to do it via the restore_attrs field:

curl -k -s -S -i -u user:pass -H 'Accept: application/json' -X POST 'https://localhost:5665/v1/objects/services/host-object!service-object -d '{ "restore_attrs": [ "vars.postgres_critical" ]}'

@yhabteab so (1) restore_attrs using REST API (2) only after that I will be able to use Icinga Director once again? No chance to update the variable directly from Icinga Directer if REST API was used, yes?

I'm not sure what you mean by that! If you create or modify something via the Icinga Director, it's basically the same as when you manually edit the *.conf files and reload the Icinga 2 service. However, you are not supposed to override values set via the REST API.

In other words, you can override values set in Icinga Director by using the Icinga 2 REST API, but not the other way around.
