+++ This bug was initially created as a clone of Bug #1856916 +++ 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
