The Activity tab was designed to answer questions such as, "What happened yesterday, as well as a month ago and a year ago?" and "What has been the performance level of my applications over time.".
Data in the Activity tab is available up to the last time slice that ended (information on the last minute is available in the Current tab). The Activity tab is usually the place to identify and investigate tuning problems.

You can use the Filter dialog box to filter the Details pane so that only the contribution of certain entities is included. See “Filtering data” on page 19 Filtering data.
The Activity tab is divided into two areas, the Tree pane and the Details pane. A breakdown of the entities that are associated with the selected entity is displayed in the Tree pane. Information on the entity you selected is displayed in the Details pane.
...
The duration value displayed next to each entry reflects the duration of each instance in the selected entity, according to the sort parameter you selected. The sort parameter is displayed next to each entity. The default entity for the top entity in the tree is In DB2 time. See “About About configuring your settings” on page 17settings.
Determining what information is displayed in the Tree
...
- Right-click on an entity in the tree, and then click Sort and Filter.
- In the Associate With dialog box, on the Entries tab, select the entity you want to associate data with from the Populate table with list.
- In the Sort entries by list, determine according to which criteria you want the information to be sorted and in which order.
- From the Display top list, select the number of rows to display.
- On the Criteria tab, do the following for each entity you want to associate data with:
From the left drop-down list Select list, select an entity.
From the middle drop-down list Select list, select an operator, such as, Like, <>, Not Like, In, Not In.
In the text box Type , type the criteria (case-sensitive) for the selected entity.
If you select the operator Like or Not Like, you can use the % wildcard character. If you select the operator In or Not In, type a comma to separate values. - Click OK.
...
You can switch to a different time frame and view additional information on the selected entity that was collected for that time frame. Only the information in the subnodes sub-nodes of the entity you have selected is refreshed.
...
When database files are stored on an EMC Storage unit and the Precise for Storage agent is installed, a tab named Storage is displayed. The tab presents a list of storage device used by the DB Partition entity. For each storage device it displays statistics regarding Cache Hit Ratio, Containers and Table Spaces, Requests amounts, Throughput, and I/O rate. See “Storage tab” on page 46 Storage tab.
When information on a selected entity is displayed in table and graph format in the Details pane, there is a direct correlation between the selected entry in the table and the information displayed in the graph below the table. Selecting a different row changes the information displayed in the graph displayed below the table.
...
The Activity tab displays information on different entities. This section provides an overview of all entities, their meaning, and their views. See “The The Precise for DB2 Time Model” on page 12Model.
The following entities can be examined in the Activity tab:
