Any SQL Server monitoring tool must gather the metrics that will allow a DBA to diagnose CPU, memory or I/O issues on their SQL Servers. It should also provide a set of accurate, reliable, configurable alerts that will inform the DBA of any abnormal or undesirable conditions and properties, as well as specific errors, on any of the monitored servers. This article provides an in-depth guide to the monitoring and alerting functionality available in one such tool, Redgate SQL Monitor. It focuses on the latest edition (5.0), which includes several key new features, such as performance diagnosis using wait statistics, the ability to compare to baselines, and more.
