SLO + Management Zone Existence Timing Bug

[ghost]

Describe the bug
When I use monaco to create a management zone and an SLO which utilises that management zone as a filter, the Dynatrace API throws a 400 because monaco has not yet created the zone.

ERROR 	Failed to create DT object appone availability (HTTP 400)!
    Response was: {"error":{"code":400,"message":"SLO validation failed with 1 error(s):\nGiven filter is invalid."}}, responsible config: projects/baseconfig/slo/synthetic_availability.json

For example, my SLO filter is:

mzName(appone),type(HTTP_CHECK)

And I've also asked monaco to create the appone management zone. Monaco will attempt to create the SLO first:

INFO  Processing environment preproduction...
INFO  	Processing project projects/baseconfig...
DEBUG 		Deploying configs in this order: 
DEBUG 			1: projects/baseconfig/slo/synthetic_availability.json
DEBUG 			2: projects/baseconfig/management-zone/app.json

Potential Solutions
I believe there are two potential solutions:

1. Create the zone before the SLO or
2. Ask for DT API to be modified so that it doesn't check the existence of a management zone first and allows the SLO to be created "in good faith"

There is a third potential solution but it involves not using a management zone (so not strictly a workaround for this issue but it'll get you working again).

My scenario above was that a synthetic script would be created which is tagged as app:whatever. My management zone includes HTTP_CHECK objects with the app:whatever tag so instead of using the mzName filter, I just directly filter HTTP_CHECK for ones with that tag value:

- filter: "type(HTTP_CHECK),tag(app:whatever)"

Spoken to DT SLO team and they enforce that the filter is valid.
What that means for Monaco is that the zone must exist before the SLO is created - so I think the fix here is to ensure any zones are deployed before SLOs.

Hi @Dynatrace-Adam-Gardner, if you have both MZ and SLO defined in monaco, you just need to reference mzName in SLO yaml as: zone-name: /my-project/management-zone/my-zone.name and monaco will take care of deploying SLO after MZ is created.
