Monitoring SQL Server Performance Monitor objects (Perf Mon for those in the know) can be an important part of monitoring your SQL Server instance. Finding information about the performance monitor objects that SQL Server exposes can be tricky, even though the SQL Server Project Team can documented what these objects all mean.
You can find the documents about the SQL Server Perf Mon objects online on the Microsoft docs website.
If you haven’t had a chance to check it out, I’d very much recommend it. If you are looking for which objects you should be monitoring this can answer a lot of questions for you.
