Can it send job level metrics only?

[jduan-highnote]

When the collect-job-metrics flag is set to true, metrics at the job level as well as step level are sent to datadog. This doesn't work well if a workflow has a lot of jobs and steps. For a large workflow we have, not every job & step level metric is sent to datadog because I think there's a limit.

Can this flag be broken down to two flags?

• collect-job-metrics (collect job-level metrics only)
• collect-step-metrics (collect step-level metrics only)

That way, people can choose what they want. Thanks!

BTW, I've seen this error as well Error: HTTP-Code: 413 Message: {"errors":["Payload too large"]}. It can be avoided if there's a more granular configuration of what metrics to send.

It seems Datadog metrics API has 10MB limit.
open-telemetry/opentelemetry-collector-contrib#1925

I will add a flag of collect-step-metrics. It would be also effective for the custom metrics cost of Datadog.

I think it is possible to send the metrics by multiple requests. I will try it as well.

According to the API doc https://datadoghq.dev/datadog-api-client-typescript/classes/v1.MetricsApi.html#submitMetrics, the maximum payload size is 3.2MB.

Thanks for fixing this so quickly!

@int128 quick follow up: I have a very large workflow that has many jobs (actually the number of jobs is dynamic). It seems that job-level metrics are capped at 399? I see this in the log Sending 399 metrics to Datadog. Due to this limit, some of the job metrics aren't sent. Can all the job metrics be sent in batches?
