Description Neha Ojha 2020-07-14 17:23:41 UTC 
The progress module in the manager causes a lot of load, especially if the cluster is not healthy. This results in blocking of other modules like the prometheus endpoint.

Skip pg_summary update if _events dict is empty since the get call of pg_stats and pg_ready are expensive and are not necessary in this case. This avoids blocking other modules like the prometheus module
