13.6 Daily sanity checks This section shows you how to perform basic, yet important, system validations on your Tivoli storage Manager environment. These checks are run manually, but obviously many could (and should) be automated. We show the commands using the CLI. The same information is also available from the Administration Center; however, use of the CLI allows you to script these commands. We recommend that you start by issuing these commands daily. Then once you feel confident that the environment is performing smoothly, you might switch to a weekly schedule for some of the commands, to balance the amount of information to process with the need to keep informed. You should run monitoring commands as part of the daily operations check, as a sync-point for all your administrators, especially if there are multiple teams working different shifts and locations. Tivoli Storage Manager has a rich set of commands that allow you to monitor and create your own reports. The query command set is the base for most information form the server. Type help query or help query for more details about all of the options. Display database information This section shows important Tivoli Storage Manager queries for the database and recovery log. The queries are listed in alphabetical order. To display information about your current database occupancy and how much space is still available for extension, use the query db command, as shown in Example 13-12.
