The Diagnostic & Monitoring Tool supports two sets of settings that a user can configure:
User configuration controls how the Diagnostic & Monitoring Tool presents information to the user. For instance, you can adjust the series each graph will display or the default polling interval for tables. These parameters are available to every user and will only affect the user who made the change.
Server configuration contains the settings that affect behavior of the server and, therefore, every user. Only the administrators of the Diagnostic & Monitoring Tool have access to this configuration.
