The Monitors associated with a test composition provide valuable feedback about the performance of the CloudTest machine, as well as ancillary servers, application servers, and databases.
To change which monitors start when playback of a test composition begins:
- Click the Properties tab in the lower toolbar.
- Then, with Composition selected in the tree control, click the Monitoring tab. The defined monitors appear.
- Check those monitors you'd like to start with this test.
Monitors defined via the Central list > Monitors node can be viewed from the Monitors list > View Analytics link or added to the dashboards associated with the test composition.
Monitor widgets can be added to dashboards individually or grouped via the Monitor Container and viewed as a dashboard or contained within still other dashboards. The screenshot on the right shows the Monitor Summary for a multi-server environment.
Database Monitoring Widgets
There are eight database-related monitor dashboard widgets for the eight new resource types. These are found in the Widget Type Selection Panel's Widget Type, Monitor category:
Buffer Cache Size – The size of the database buffer cache, in bytes.
Deletes – The number of DELETE statements issued to the database (MySQL, Oracle, SQL Server), or the number of rows deleted from the current catalog (PostgreSQL).
Disk Sorts – The number of sorts that required creating a temporary table on the disk. This metric is not supported when monitoring PostgreSQL. The Disk Sorts widget does a simple count. When the count is zero, the Y-axis lists 1, 2, 3, 4.
Full Table Scans – The number of full table scans across all queries.
Index Scans – The number of index scans across all queries.
Inserts – The number of INSERT statements issued to the database (MySQL, Oracle, SQL Server), or the number of rows inserted into the current catalog (PostgreSQL).
Selects – The number of SELECT statements issued to the database (MySQL, Oracle, SQL Server), or to the current catalog (PostgreSQL).
Updates – The number of UPDATE statements issued to the database (MySQL, Oracle, SQL Server), or the number of rows updated in the current catalog (PostgreSQL).
