v Workspace graphs or tables contain short-term but not long-term historical data.
v Summarized historical data is not displayed.
v You suspect that the values returned for historical data are incorrect.

Diagnosing that historical data is missing or incorrect

You can diagnose that historical data is missing or incorrect by using workspaces
such as the Self-Monitoring Topology workspace to verify component activity.
Also, you can use the tacmd commands to verify the configuration of historical
data.
