In this episode of "PerfMon Counters for the SQL Server DBA," SQL Server MVP Kevin Kline starts a new discussion and turns his focus specifically on SQL Server counters. Kline shares best practices for using access method counters to watch for IO intensive operations, such as full table or clustered index scans and page splits. You'll also learn why it's important to monitor the buffer manager in SQL Server, i.e, keep an eye on lazy writer, page utilization and how quickly pages age out of the buffer.
Kline also discusses these SQL Server Performance Monitor Counters:
Ideal ratio for page splits to batch requests and how to get the lowest number by using clustered indexes and setting your SQL Server at a reasonable fill factor.
Buffer cache hit ratio for both OLAP and OLTP systems.
How a high ratio of page lookups per second to batch requests per second could indicate you have an inefficient query plan and query tuning is in order.
Optimal ratio for page reads/ page writes per second and why high numbers could mean index problems or memory constraints within SQL Server.
