Table Performance Tab

The Table Performance information is provided in a table.

To enable the data collection for a database and to display this data on the Table Performance tab, the database must be added to the Table Space Monitoring list in the Table Space Management group of the Sybase_MDA Agent properties. For more information, see Setting Table Space Management Properties .

The filters appearing just above the table allow you to look for specific entry based on some known criteria. You can filter on table and/or database name, choose between showing the table and/or indices, show delta values or rates, and indicate if you want to display the data collected in the last collection period, most recent sample, or in the last ten minutes.

Table Name

For table entries, this column contains the table name. If the table has one or more partition, the table node can be expanded to show the names of table partitions in this column.

For index entries, this column contains the name of the table associated with the index.

When the row shows information about a table, clicking this column shows additional information in the Table Performance Drilldown. For index entries, clicking this column shows the Index Usage Drilldown. Clicking a partition the Partition-Table Usage Drilldown.
