Hi Everyone , i am using flink JDBC Connector for sinking data to postgres db. i wanted to have some alerting mechanism incase my flink job is disconnected from Postgres db . i am not able to figure out any jdbc connector related metrics that i could use to raise an alert . Is there any metrics available to check out postgres connection status , if not how can i implement a custom metrics of type guage to perform this task.
