View and modifying performance chart data

Overview
The View Chart tab displays a graph with time as the x-axis and the performance value as the y-axis.
1. Click a resource in the Resource Selection panel.The Resource Selection panel, located on the left side, provides a hierarchical (tree) view of resources and the types of performance data available for those resources. Use this panel to select which resources to monitor and to start and stop data retrieval for those resources. See Tivoli Performance Viewer features for information on the Resource Selection panel.
2. Click the View Chart tab in the Data Monitoring panel. The Data Monitoring panel, located on the right side, enables the selection of multiple counters and displays the resulting performance data for the currently selected resource. It contains two panels: the Viewing Counter panel above and the Counter Selection panel below. If necessary, you can set the scaling factors by typing directly in the scale field. See Scaling the performance data chart display for more information.












Refreshing data

Overview
The refresh operation is a local, not global, operation that applies only to selected resources. The refresh operation is recursive; all subordinate or children resources refresh when a selected resource refreshes. To refresh data:
1. Click one or more resources in the Resource Selection panel.
2. Click File > Refresh. Alternatively, click the Refresh icon or right-click the resource and select Refresh.Clicking refresh with server selected under the viewer icon causes TPV to query the server for new PMI and product configuration information. Clicking refresh with server selected under the advisor icon causes TPV to refresh the advice provided, but will not refresh PMI or product configuration information.
Clearing values from tables and charts

Overview
Selecting Clear Values removes remaining data from a table or chart. You can then begin populating the table or chart with new data.

Overview
To clear the values currently displayed:
1. Click one or more resources in the Resource Selection panel.
2. Click Setting > Clear Buffer. Alternatively, right-click the resource and select Clear Buffer

Resetting counters to zero

Overview
Some counters report relative values based on how much the value has changed since the counter was enabled. The Reset to Zero operation resets those counters so that they will report changes in values since the reset operation. This operation will also clear the buffer for the selected resources. See "Clearing values from tables and charts" in Related Links for more information about clearing the buffer for selected resources. Counters based on absolute values can not be reset and will not be affected by the Reset to Zero operation.
To reset the start time for calculating relative counters:
1. Click one or more resources in the Resource Selection panel.
2. Click Setting > Reset to Zero. Alternatively, right-click the resource and click Reset to Zero.
