It is easy to get database monitoring wrong. There are several common-sense rules that can make all the difference between a monitoring system that works for you and helps to avoid database problems, and one that just creates a distraction. Adam Machanic spells out the rules, based on his considerable experience with database monitoring.  Read more...

Our major goal in terms of log maintenance for all databases under our care is to optimize for write performance, in order to support all activities that require SQL Server to write to the log, including data modifications, data loads, index rebuilds, and so on. However, it's also important to keep an eye on possible log fragmentation, which, as described previously, can affect the performance of processes that need to read the log, such as log backups and the crash recovery process.  Read more...

SQL Monitor comes with plenty of metrics, but there are always going to be things that you want to measure that can't be done 'out of the box'. Taking database mirroring as an example, Grant shows that custom metrics can be used to monitor and alert whatever aspect of SQL Server or database that you need.  Read more...

SQL Monitor’s Job duration unusual alert is a powerful tool for keeping track of most jobs in your SQL Server environment. It works by comparing the running time of any job instance against the median for that job, and identifying when a variation in the job duration could hint at a performance problem. However, if your environment contains big jobs whose durations vary by several orders of magnitudes, it can be tricky to specify what kind of variation is expected and what would be unusual. For these cases, it is possible to go beyond the functionality of the built-in alert with a custom metric.  Read more...
