Does Datadog Support adding custom tags to Job Spans/Pipeline Traces from the API?

[mrk-han]

I need to add a custom tag to a previously existing job execution.

I am already using datadog-ci to upload jobs to DD, but I want to run analysis on the job traces then POST back to that same Job Event with a custom tag to help sort the jobs within datadog

Right now, I'm trying to see if it's possible to do this with the datadog API directly because the datadog-ci tool won't be available from the context where I need to send the request.

I'm using https://docs.datadoghq.com/api/latest/ci-visibility-pipelines/#search-pipelines-events to get information about the Job, then sending as much info as I can find to POST pipeline event (option 3) https://docs.datadoghq.com/api/latest/ci-visibility-pipelines/#send-pipeline-event

Right now, it's adding the tag correctly but creating a new pipeline execution instead of editing the previous pipeline execution.

Hey this seems something related to Datadog general rather than something specific to datadog-ci CLI. For this I would recommend reaching out to support directly if possible for future questions / concerns.

Several things:

• When sending jobs using the API you can set there the custom tags you need using the tags field.
• If the desired behaviour is to first send the job and then update the same job later by adding more tags to it, I am afraid this is not currently supported and this would need to be a feature request. Can you confirm if this is the case?

Thanks!

That is our desired behavior -- the job is sent first via the pipeline, then we would analyze the trace and update the same job later by adding more tags which would help to classify the failures.

Is this behavior possible via the API or Datadog-CI tool via CLI?

I also posted in Slack here

From Slack:

Update: We found that using a GitLab job's after_script: to call datadog-ci tag works for our purpose. It seems to happen before the GitLab Datadog Integration sends its webhook to DD for that Job in a way that when the integration makes its call everything just works. We have to do our analysis in the after_script which isn't ideal, but we think it will work for now.

For a feature request: it would be nice to be able to POST or PUT to update facet tags (or other info) using a pipelineID, jobID and some sort of ID unique to that job's execution.

@rodrigo-roca What is the process for creating this as a feature request?

Hey sorry for the delay on the reply, just want to inform you we already created one internally so there is no further action required on your side. Thanks for reaching out!
