ChaosCenter portal doesn't display experiments' Chaos Results #3847

Open dsanchez31 opened 1 year ago

dsanchez31 commented 1 year ago

What happened: I've installed Litmuschaos from litmus-helm repo v2.15.1 at cluster scope on a k8s cluster (v 1.24.4) with ChaosHub (branch v2.14.x) I run generic/pod_delete on another namespace. It works but (most of the time) I can't view Chaos Results and Reliability Details (Overall RR always 0% and Experiments Passed : 0/1) while "kubectl describe chaosresult -n litmus" displays expected results.

What you expected to happen: I would like to see Chaos Results and Reliability Details in ChaosCenter as there are stored in chaosresult k8s objects".

How to reproduce it (as minimally and precisely as possible): Install Litmuschaos v2.15.1 and run some experiments (generic/pod_delete for example).

Thank you for your help

Here, logs of the subscriber: When requesting from the UI the logs of an experiment missing results:

Hi, The issue seems to occur when the k8s cluster is overloaded...

Hi @dsanchez31 We are unable to re-create this issue, we installed litmus-helm repo v2.15.1 as you have mentioned.

Hi, The issue seems to occur when the k8s cluster is overloaded...

Can you please tell your cluster resources? We will try to create the same env and test on it.

  1. Check the versions of Litmus Chaos and ChaosHub: Make sure that you are using compatible versions of Litmus Chaos and ChaosHub. The version of Litmus Chaos and ChaosHub should match, or at least be close in version number.
  2. Check the status of the ChaosHub deployment: You can check the status of the ChaosHub deployment by running the following command: kubectl get pods -n litmus
  3. Check the connectivity between Litmus Chaos and ChaosHub: Make sure that Litmus Chaos and ChaosHub can communicate with each other. You can check the logs for the Litmus Chaos and ChaosHub pods to see if there are any connectivity issues.

4.Check the configuration of the ChaosHub deployment: Make sure that the ChaosHub deployment is configured correctly. You can check the values in the chaos-hub-values.yaml file to ensure that the configuration is correct.

Hi, this is still happening when using custom defined manifests (if using chaosCenter UI it works), did you find any solution?

version: beta3 scope: namespaced
