SQL Server overall performance Monitor with Best Practices
Posted: Nov 21, 2017
Database administrators want to know each SQL Server’s weakest link so we know in which to attention their hardware budgets and time. On any given server, need to know what the slowest element is, and wherein it will pay off to make investments hours and bucks. This is performance tuning, and the first place to begin is with the aid of the usage of overall performance monitor.
Overall performance monitor, measures overall performance information on a regular programming language, and saves those stats in a file. The database administrator picks the time programming language, report format, and which facts are monitored. After the stats are gathered over a time frame (hours or days), we can do analysis by using starting the results in Excel and putting in some basic formulas.
Performance isn’t only for SQL Server tuning: system administrators use it to monitor overall performance on windows itself, Exchange, file and print servers, and anything else that can run into bottlenecks. As a result, it’s clean to locate Perfmon data online, but it’s not continually precise to SQL Server. Seeing that every application has its personal set of information, it facilitates to get SQL related tips.
Setting up Perfmon for SQL Server Tuning
On your desktop or laptop (not the SQL Server itself), go into control Panel, Administrative tools, overall performance. The first factor that comes up is a 1990’s-looking line chart with a few basic performance stats on your workstation itself. Exciting, however now not what we are after.
On the left side, expand performance Logs and signals, and click on Counter Logs. Counter Logs allow us to pick out a hard and fast of performance counters and log them to a document periodically. One counter log is listed by default; however we’re going to feature a brand new one. Right click on counter logs and click new log settings. Name it with the name of your database server; due to the fact each server must have its personal log settings. We may want to theoretically build a single counter log for all of our database servers, but then whenever we need to run the counter log in opposition to one in every of our servers to check its performance, it will log statistics for all servers, and that’s no longer commonly how we need to do performance tuning. After typing in a name, we can begin putting in the counters we want to log.
