Monitor named "Performance Data collection health" needs to be fine tuned in a way that it does not overload the SQL Server when enabled.
The default SCOM monitor named "Performance Data collection health" which is disabled by default, needs to be fine tuned in a way that it does not overload the SQL Server when enabled for 1000 + Agents. The way the SQL query is built it looks like running it against 1000+ Agents will cause performance issues on the SQL server.
The purpose to enable this monitor is to identify if Performance data is stopped collected / missing for specific Agents in last few hours.
Request the product group to review the request to see we can ship this by default enabled and optimized to work on a large environment with around 2000 + Agents.
