Database Workload Analysis

SQL Server, unlike SQL Server, is a shared environment in which many databases compete for memory and background process (lazy writer, etc.) attention. This being the case, it is smart to identify if any databases are using the lion’s share of resources. Pinpointing these workload hogs can help direct the DBA to the root cause of any sluggishness exhibited by SQL Server.

For databases, the process begins by a review of overall resource consumption and activity. In this process, the DBA is looking for any databases that seem to stand out from the others in terms of overall usage and dynamics. On the resource usage front, a good query to use for this process is the dbusage_overview.sql query:

* dbusage_overview.sql

-- Script is available in the Online Code Depot

The query does a nice job of showing which databases are currently responsible for the most resource usage.

After performing the above query, the DBA can then try to get a handle on the types of activities that have gone on in each database by issuing the dbactivity_overview query:

* dbactivity_overview

-- Script is available in the Online Code Depot

This query helps the DBA understand which databases are seeing transaction log extends, and which ones are experiencing the most transactions, etc. Once armed with usage and activity information, applications and databases responsible for the primary workload on SQL Server become more apparent.
