Performance Counters – 2

Filed under: Performance,Tips — Triaged Tester @ 1:07 pm

Performance monitor for SQL Server

Counter Name Collection Notes Comments
SQLServer:Access Methods – Full Scans / sec   Value greater than 1 or 2 indicates that we are having table / Index page scans. We need to analyze how this can be avoided. 
SQL Server:Cache Manager – Cache hit ratio   The ratio between the cache hits and misses. This counter is a good indicator of our caching mechanism in SQL Server. This value needs to be high in the system
SQL Server:Databases – Transactions/sec   This number indicates how active our SQL Server system is. A higher value indicates more activity is occurring
SQL Server:Databases – Log growths   The number of times the log files have been extended. If there is lot of activity in this counter we need to allocate static and large enough space for our log files. 
SQL Server:General Statistics – User Connections   The number of users currently connected to the SQL Server.
