[ACTION] Proposal 3 - Collect & Compute

[AntonioDiTuri]

This issue details what needs to be done in the collect step.

You can reference the proposal 3 - Metrics section: https://github.com/cncf-tags/green-reviews-tooling/blob/main/docs/proposals/proposal-003-report.md#metrics.

There three substeps:

1. collect the project metrics
2. collect the metadata
3. compute the sci

1. The metrics we will need to collect are

container_cpu_usage_seconds_total
container_memory_rss
container_memory_working_set_bytes

All the metrics should be available in prometheus, and we should be able to collect them with a PromQL query.

2. Collect the metadata

After collecting the metrics we need to collect the metadata: https://github.com/cncf-tags/green-reviews-tooling/blob/main/docs/proposals/proposal-003-report.md#metadata

3. Compute the sci

We can run the PromQL query which is already available using the Prometheus Go Client:

This could be done by starting a Prometheus Go client: https://github.com/prometheus/client_golang

I would like to work on this issue

@qasmi I was going to work on part 3 of this task, so let me know if you get assigned this ticket.

Once you've got your structure in place, and then I can create a module for the storage part and fit in with your design.

[qasmi]

@SRF-Audio I will let you know. Sorry for the late response !

[AntonioDiTuri]

I will assign you both and then you can sync on how to split, what do you think?

[SRF-Audio]

Works for me!

Hi guys! Any updates on this one? @qasmi @SRF-Audio
Let me know if you need support :)

I can take on this issue

Hey folks! We split this into three issues:

• Collect project metrics through Prometheus client #159
• Collect the metadata through Prometheus client #160
• Compute the SCI through the Prometheus client #161

@dipankardas011 will work on the first one that also sets up the Go application with the client that fetches metrics from the Prometheus HTTP API.

After that initial setup of the Go client is done, we should be able to work on fetching the 3 sets of metrics separately. You are welcome to follow up on #60 and #61. Thank you for your time and willingness to contribute to the project! :)

Hey @AntonioDiTuri sorry, last couple of weeks I was swamped. I get back from Barcelona next week, and I'll have some time to look at these.

Hi, sorry for the delayed response! I've been overloaded with work lately and haven’t had a chance to look into this issue yet. I'm slowly getting back on track and should have some time to work on project soon.
