custom source link on alertmanager

[isshwar]

Hi All,

I am using alertmanager in conjuction with loki and pagerduty i.e, loki -> alertmanager. -> pagerduty. Now, on the alerts the source is empty but I want the source to be pointed to a grafana panel. how to do source in the alertmanager config/alert rule config to have a custom url and not prometheus?

Thanks
Eswar
