What is the SkewedSessions Portlet?

The SkewedSessions portlet displays skewed active sessions for any AMP that is causing a system-wide skew.

This portlet demonstrates:

  • Selecting a system to monitor using preferences
  • Getting data from the Cache DB
  • Implementing business logic
  • Using the Table Widget

Be aware

The SkewedSessions portlet requires a working Data Collection Service(DCS) to display meaningful data. If you do not have access to a DCS, it is still recommended that you step through this tutorial, as it introduces several important concepts, but note that the completed portlet will not display any data.
