I am using istio.1.6 and i was trying to store metrics from istio prometheus to external prometheus based on istio best practise doc.But in the first step, I have to edit my configuration and add recording rules.I tried to edit the configmap of istio prometheus and added the recording rules.Edit is successful but when i try to see the rules in prometheus dashboard ,they donot appear(which i believe means the config didnot apply).I also tried to just delete the pod and see if the new pod has new configurations but still the problem. What am i doing wrong? Any suggestions and answers is appreciated.

The problem was that the way I added the recording rules.I added rules in rules.yaml but forgot to mention it in rule_files field of the prometheus config file.I didn't know how to do prometheus configuration and that was the problem.
I also refered this github example
