Increased resources consumption configuring some sources

Description

We use Botkube mainly to receive alerts based on specific events.

Migrating from 0.18.0 to 1.8.0, we translated the configuration from old (0.18) to new (1.8) syntax, but we face some issues:

  • we see error logs same as described in the Slack thread https://botkube.slack.com/archives/C01CR1KS55K/p1708685516373879.
  • Botkube keeps restarts because of livenessProbe failing (sometimes because of OOMKilled during startup, but this doesn’t occur that often), but we increased resources like: requests 1000m/1Gi, limits 3000m/3Gi. We set those values based on Grafana spikes we observed. To be honest they look really high, especially if compared to version 0.18! Actually it seems that the adoption of the plugin model increased exponentially the resources usage 😞

Please note that the above mentioned issues happen also with the default global_config coming out of the helm-chart with following sources enabled: k8s-all-events, k8s-create-events, k8s-err-events, k8s-err-with-logs-events, k8s-recommendation-events

Expected behavior

Even with many configured sources, Botkube should consume up to 1000m cpu and 1Gi mem, like in older versions <= 1.0.0

Actual behavior

With many configured sources, Botkube consumes up to 3000m cpu and 3Gi mem.

Steps to reproduce

Just deploy Botkube using following configuration:

expand

@mszostok posted this answer in Slack thread https://botkube.slack.com/archives/C01CR1KS55K/p1709121554586339

Thank you for upgrading! I've reviewed your configuration, and I agree with your observation about its similarity to the previous report.

I think that I know what could cause that. The common thing is that you have a lot of dedicated k8s source configurations, and you are also watching a lot of different resources. It's great to see such usage 🎉

I believe the root cause is directly connected with changed kubernetes source implementation. In our current approach, a new shared informer is created for each Kubernetes source (see: [source.go#L122]). Unlike the previous method, which had a single informer based on merged all configurations, the current approach results in multiple in-memory informers for each configuration - making it N times.

To address this, I think that we should refactor our approach and introduce a global informer, similar to the one we had in v0.18. This should help resolve the issue.

Could you please create a GitHub issue for this? We'll further refine it and try include it in our next planning 👍 However, since the kubernetes code is fully open source, if you find the time to experiment with refactoring and testing this approach, it would it would be amazing! 🙂 If not, we will try to handle it in our team and keep you posted 👍

Hi @bygui86, good news! The issue has been resolved in #1425 which is now merged to the main branch.

The Botkube 1.10 release is planned for next week but, in the meantime, could you please test Botkube from the latest main to confirm your issue is gone?

The following command should do the trick:

botkube install --repo https://storage.googleapis.com/botkube-latest-main-charts --version 0.0.0-2cb5eacc # add your own overrides here

In case you use other way for the Helm chart installation, here are the details:

  • Helm repo: https://storage.googleapis.com/botkube-latest-main-charts
  • Helm chart version: 0.0.0-2cb5eacc

However, remember to keep the following overrides:

image:
  pullPolicy: IfNotPresent
  registry: ghcr.io
  repository: kubeshop/botkube
  tag: 0.0.0-2cb5eacc # use the latest Botkube Agent image

plugins:
  repositories:
    botkube:
      url: https://storage.googleapis.com/botkube-plugins-latest/plugins-index.yaml # use the latest plugins

Hope that will fix your issue and you'll be able to upgrade to the latest Botkube. Cheers!

@pkosiec thanks a lot for your effort! The memory consumption in the MR looks really promising!
Unfortunately I don't have time to test it in the next few days :( I will try to upgrade to v1.10.x when I get a spot :)
Keep you posted!
