This metric reports the total space used by database files in GB. This includes data files but excludes log files. This lets you track the growth of the databases over time so you can be aware of future space requirements. Alternatively, the following T-SQL can be used for SQL Server 2012 and higher: [crayon-599a4baae8420572682861/] Read more
This metric measures the number of available autogrowth steps for a database, so you can see when they are reduced or increased because something else (e.g. another database) starts or stops taking up space, when storage is added, etc. Read more
This metric measures the percentage of database free space - both reserved and unused - to help you manage space requirements more efficiently. For example, you might find this data helps you to correctly estimate file size, so you don't suffer from problems with automatic file growth. Read more
This metric measures the ratio between used database space and total available space, also taking into account current size, maximum size and the amount of free space for each drive. The values collected help you maintain control over the database storage area, and monitor database growth in combination with general space management on a database file's host. Read more
It’s important to measure the growth of databases so you can plan future space requirements, prepare for time periods when heavy volume traffic is expected, and take action in advance to prevent problems such as highly fragmented databases. Read more
This metric is useful if you want to know exactly how much physical space a particular table is taking up, including the size of its indexes. Read more
What are custom metrics?
The SQL Monitor custom metric feature lets you run T-SQL queries against your SQL Servers to collect specific data. You can analyze and receive alerts about your custom data just like everything else SQL Monitor collects.
But what if you don’t want to write your own queries? No problem. Redgate has brought together a range of quality custom metrics for you to use in SQL Monitor, which are all are free, tried and tested. You can install straight away, and use the resources on this site to help you write your own.
This metric returns the number of non-Microsoft modules loaded into the SQL Server address space. Having a lot of modules loaded into the address space can cause performance issues in SQL Server. This metric lets you keep an eye on how many modules you have, other than those created by Microsoft. Thanks to Nicolaas Botes for […] Read more
This metric and alert will notify you when a SQL Server instance is restarted for any reason. The value returned by the metric is not useful on its own, and is only used by the alert to detect changes. When the server has not been restarted it will report 0 , and when the server […] Read more
