![]() ![]() It executes a query which uses sys.dm_exec_requests joined to a few other DMVs. I suggest that you spend some time with the source code if you want to dig deeper. It then does some processing and store the result in temp tables so we later can sort on different columns depending on what metric we are interested in. In the Add counters dialog, locate the SQLServer:Databases performance object and expand it. There are a few things going on inside this procedure, but at the most basic level, it uses sys.dm_exec_query_stats and sys.dm_exec_requests to get queries from cache and currently executing queries. To monitor this counter, open performance monitor (PerfMon) and click on the Add counters button. AM uses a procedure named #am_get_querystats to collect the information. If you have, say, a 10 second snapshot interval, you will only see the queries executed during these 10 seconds. I fired up a workload with HammerDB against a test SQL Server 2014 instance. Activity Monitor just doesn’t give you the whole truth. But I’m not a fan of Activity Monitor, a free tool in SQL Server Management studio, which helps you look at wait stats. To view the Activity Monitor in SQL Server, users should have SQL Server System Administrator or VIEW SERVER STATE permissions on the instance. I also love analyzing SQL Server’s wait statistics. You can expand the events tracked and columns shown. The first option is the Activity Monitor, which can be accessed by navigating to the instance name, right clicking on the instance name and selecting 'Activity Monitor'. The trace will show you exactly the batch executed. Its designed to track completed stored procedures and TSQL code. Opsview has a unique approach to monitoring. To watch every query sent to SQL server using SQL profiler, you can use one of SQL Profiler predefined templates. However, its solutionssupporting Microsoft SQL Server, Oracle, MySQL, InfluxDB, and PostgreSQLcan be used both on-premises and in the cloud. This shows the most expensive queries, based on what column you sort on, executed since the last snapshot. Opsview offers a range of database monitoring solutions focused on cloud solutions. I blogged about AM a while ago, here is a part from that blog post: To dig deeper, I suggest you read the source code that these are on. Use Quick Select, Time Range, Time Zone, and time slider to set the time period of the SQL activity that you want to monitor. ![]()
