Checklist

Is this feature request related to a problem?

Yes

Problem Description

• While running

k8sgpt analyze --custom-analysis

• It will get errors from all the custom analyzer and also the active filters

• If we apply flag filter for custom analyzer name (FYI: Flag filter for custom analyzer is not supported officially, but it works) it will get all the custom analyzer errors(FYI: I have two custom analyzer).

• But I applied filter for one custom analyzer but it fetches for both resources

Solution Description

• Instead can we use flag filter to get the particular custom-analyzer error

k8sgpt analyze --filter=custom-analyzer-name --custom-analysis

Benefits

• So it will reduce the latency because it will get only the particular resource error.

• It will get only the particular resource data so the data consumption is less
