Review checklist

• PR has a meaningful title or PR has the no-changelog label attached
• Feature or bugfix has tests
• Git history is clean
• If PR impacts documentation, docs team has been notified or an issue has been opened on the documentation repo
• If this PR includes a log pipeline, please add a description describing the remappers and processors.

Additional Notes

Note that an official integration submission has been submitted as well. Please also note that we need to release a new agent version that updates the metrics naming convention to be compliant with the Datadog requirement. I am waiting for a first round of review to actually make the change.

I think there's something broken in our linter job, it should've flagged all the extra empty lines at the top of a lot of python files.

And for python, we moved to python 3.12 a while ago, the scaffolding must be using an older template.

@epot can you confirm what ddev version you're using?

[jhgilbert]

Just flagging for the team that I'm the docs reviewer for this integration. Thank you!

[epot]

@epot can you confirm what ddev version you're using?

$ ddev --version
ddev, version 11.2.0

@NouemanKHAL for some reason github didn't let me commit your suggestions, but I updated the PR with your changes unless I have done something stupid.

@epot we're working on unblocking you with the validations. When you get a chance, could you update your fork with the latest master and push it here?

[epot]

@iliakur done. But the CI is very sad and I am not sure if it's my fault or not :D
If you have time to show me how I can reproduce this error that would help: https://github.com/DataDog/integrations-extras/actions/runs/15204445512/job/42764383682?pr=2661

[iliakur]

@epot you can comment this line out to get the tests to run/pass.

I'm working in parallel on the validation. Your PR is off the beaten path in some regards, our checks need some adjustments.

[epot]

ok!
