Getting Started with IBM Data Studio for DB2

142 Getting Started with IBM Data Studio for DB2
You can configure the web console to send you an alert when it identifies a problem with a
database that it is monitoring. The web console generates alerts based on the thresholds
and settings that you specify. When you add a new database for monitoring, a default
configuration of thresholds and settings is already specified for you. You can alter the
default configurations from the Health alert configurations page as described in Section
4.5.4. You can view the generated alerts by clicking the Open menu, and then selecting
either Health -> Health Summary or Health -> Alerts.
The Health Summary provides a grid of summary health information for each monitored
database, as shown in Figure 4.4.
Figure 4.4 – The health summary
The alert icons in the grid cells identify a database status (Normal, Warning, or Critical)
across categories such as data server, connections, storage, and recovery. A double dash
(--) in a cell indicates that no alerts were issued in the selected time frame, as indicated by
the time duration selection in the upper left hand corner of Figure 4.4. Each icon represents
a summary of one or more individual alerts that were encountered for the selected duration
of that specific database. For example, if you had two Storage alerts for a database, one
Critical and one Warning, then the alert summary icon would identify this as Critical. When
you click on the cell, you can drill down to the individual alerts themselves that detail the
problems, including any appropriate actions you should take.
You can view alerts for specific time periods by selecting the Summary time drop-down
menu, currently set at 60 minutes in Figure 4.4. If you set your recent summary to 60
minutes, as shown in Figure 4.5, the Recent view will give you a summary of alerts that
occurred during the last hour. The refresh summary is set for 5 minutes, which means the
status will be checked every 5 minutes. You should set the refresh time to be more
frequent than the total summary period. Note that it is possible that no alerts are raised
during the most recent period.
