Calibrate Spotlight Connections

Calibrate the Spotlight home page components to display data in the way best suited to the monitored system.

Note: Spotlight automatically calibrates new connections the first time that they are opened. Use this dialog to re-calibrate a connection at any other time.

Scenario: Calibration of data flows

Data flows on the Spotlight home page indicate the rate at which data is being transferred through a system. The faster the rate of traffic, the faster the data flow moves. However, the data flow is an accurate representation of system activity ONLY if Spotlight knows the normal range of values for your system.

If the normal range of values for a data flow is from 0 to 100, a value of 8 is low, and the data flow moves slowly.

If the range of values for your system is from 0 to 10, a value of 8 is high and the data flow moves much faster.

The Spotlight calibration tool calculates the normal range of metric values for your system. Over a set period of time, Spotlight measures the changes in value of important metrics within the system. It uses this data to set the upper and lower display limits for the corresponding components. You can accept the results or adjust them if necessary.

To re-calibrate a connection

1. Select / Open the connection from the Spotlight Browser Live connections.
2. Select File | Calibration.
3. Set the Calibration period of time.
4. Click Start.

Notes:

• To stop calibration select File | Calibration | Stop.
• You can set Spotlight to save calibration data when saving configuration data in a Spotlight template. Connection Templates
