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.

Spotlight Basics describes how Spotlight applications work. It contains these sections:
Create / Modify / Delete connections to systems, and monitor those systems.
|Monitor Spotlight Connections||Monitor connections, detect alarms, investigate the cause of alarms.|
Alarms are the warnings that Spotlight raises when a metric falls outside its "normal" range of values.
|Charts, Grids and Home Page Components||Spotlight displays provide detailed statistics of the monitored system, relevant to diagnosing the cause of alarms. Make the best use of them.|
|View | Options||Customize Spotlight.|
|Troubleshooting||Solve problems using Spotlight.|
Alarms are the warnings that Spotlight raises when a metric falls outside its "normal" range of values. A new alarm is raised whenever the severity for a metric changes. When the severity returns to normal, the alarm is canceled.
Alarms are recorded in the Spotlight alarm log pages:
Many Spotlight elements use color to indicate severity.
High Medium Low Normal Information Disabled
You can configure Spotlight to notify you of changes to severity through color or intensity, audible warnings, sending email or network notifications or running a program.
|Spotlight elements whose color represents severity||Color indicates||What to do|
The open/close button on the Spotlight browser

|The highest severity currently raised - across all Live (monitored) connections.||Locate the connection in the Spotlight Browser (Live connections). Open the connection's Home Page, Alarm Log or Alarms by Time.|
The connection name in the Spotlight browser (Live connections) and connection status bar
The highest severity currently raised against the connection.
|Locate the connection in the Spotlight Browser (Live connections). Open the connection's Home Page, Alarm Log or Alarms by Time.|
|The component on the Spotlight home page||The highest severity currently raised against the component.||
Click on the component to open help regarding the alarm. The text in the help window gives some details about the alarm, why it was raised, and ways in which the problem indicated can be resolved.
Use the help to open the drilldown page that is directly related to the alarm. Drilldown pages contain charts and tables that you can use to diagnose the cause of the alarm.
You may like to view one or more related drilldown pages that may be of some value in diagnosing the problem.
Use the information shown in the help window, together with the details shown in the associated drilldown page(s), to discover why Spotlight has raised the alarm.
If the alarm is transient, you at least will see where in the system it occurred. If the alarm persists, Spotlight indicates what measures need to be taken to resolve the problem.

Spotlight Today shows recent alarms for all Spotlight connections. Spotlight Today can be grouped or filtered to show alarms by connection or severity. Spotlight Today displays: the number of current Spotlight connections, the number of connections for which an alarm has been raised, a Spotlight Today entry for each alarm raised.
