Fluxv2 datadog integration

[melchiormoulin]

Hello just to inform you that Blablacar developed a Datadog integration for flux2
This enable to scrape metrics from datadog agent.

@melchiormoulin this looks great, we could add the integration to https://fluxcd.io/ecosystem/#integrations

Is anyone using this integration successfully? The example config (https://github.com/DataDog/integrations-extras/blob/master/fluxcd/datadog_checks/fluxcd/data/conf.yaml.example) is just a default template.

From the code, I think one needs to point the config to the flux metrics endpoints?

For people finding this ticket, if you're using helm you want to add values like this to your helm chart if using datadog (after also installing the fluxcd agent in your dockerfile): (Do the same for the other controllers (notificationController/kustomizeController/etc)

      sourceController:
        annotations:
          prometheus.io/scrape: "false"
          ad.datadoghq.com/manager.checks: |
            {
              "fluxcd": {
                "instances": [ {
                    "openmetrics_endpoint": "http://%%host%%:8080/metrics"
                  } ]
              }
            }
        labels:
          tags.datadoghq.com/source: source-controller
          tags.datadoghq.com/service: source-controller

How to install the fluxcd agent in your dockerfile

FROM datadog/agent:7.44.0
RUN agent integration install -r -t datadog-fluxcd==0.0.1

@cep21 What's the reasoning behind:

prometheus.io/scrape: "false"

[melchiormoulin]

Hello @teocns this annotation is to not scrape metrics as custom metrics.
Fyi now the flux integration is a core integration.

Anybody managed to get this setup with datadog-operator?

I too am having trouble getting this to work. The documentation seems to be lacking for this :-(
