Troubleshooting

• I have read and followed the issue guidelines and this is a bug impacting only the Helm chart.
• I have searched other issues in this repository and mine is not recorded.

@MageshSrinivasulu we'd expect this then to stabilize when you've hit your number of retention days. What's your retention number and how many days are you seeing in the UI now?

[MageshSrinivasulu]

@AjayTripathy I have set the etlDailyStoreDurationDays to 30 from its default configuration of 91 days. Can you please specify the helm configuration you are referring to?

[MageshSrinivasulu]

Below are the folders that have very high memory usage

kubecost-cost-analyzer is attached to the path /var/configs

[MageshSrinivasulu]

I had to clear some older files in the path /var/configs/localBucket/billing_integrations/<AWS-ACCOUNT>-s3:--<S3-BUCKET>/cloud_costs/bingen/1d on the pod to solve the issue temporarily. This will not be a sustainable solution in the long run. How to configure this routine clean up using helm deployment?

@AjayTripathy Is this the one you are speaking about?

[AjayTripathy]

yes. It will gradually increase until that time window then should stabilize.

[MageshSrinivasulu]

It has been more than 30 days since I made the changes. It keeps decreasing gradually. It is not getting stabilized
