8 Statistics Viewer Module

The Statistics Viewer screen shows a list of the monitored statistics and allows the list to be edited. A default list of statistics to show are configured. It contains these tabs:

• Configure Statistics. See Configuring Statistics.

• View Statistics. See Viewing Statistics.

Configuring Statistics

Use the Configure Statistics tab of the Statistics Viewer screen to add, edit, and delete system statistics. Available system statistics are managed through the statistics management screens.

Each line of the table contains the details of a single statistic and the configured warning ranges. The statistic name is taken from the statistic definitions in the SMF database. The minimum and maximum values for each range are entered by the user.

SMS statistics are simply stored as numbers, so the context of the ranges needs to be determined by the user. In the example data, the statistics are all percentages, but other statistics might count the number of certain events or measure absolute amounts (for example, disk usage in KB).

The statistics settings are stored in a database table in the SMF and queried when the screen is loaded. This allows the same statistics to be monitored across different SMS screen sessions.

Note: The configuration is a global configuration, and not a per-user one.
