Advice type
Categorizes the primary indent of a piece of Advice.
Use Advice type for grouping, and then enabling or disabling sets of advice based upon your purpose. Advice has the following types:
- Performance: Performance advice provides tuning recommendations, or identifies problems with your configuration from a performance perspective.
- Diagnostic: Diagnostic advice provide automated logic and analysis relating to problem identification and analysis. These types advice are usually issued when unexpected circumstances are encountered by the application server.
Performance impact
Generalizes the performance overhead that an alert might incur.
The performance impact of a particular piece of advice is highly dependant upon the scenario being run and upon the conditions meet.
The performance categorization of alerts is based upon worst case scenario measurements. The performance categorizations are:
- Low: Advice has minimal performance overhead. Advice might be run in test and production environments. Cumulative performance overhead is within run to run variance when all advice of this type is enabled.
- Medium: Advice has measurable but low performance overhead. Advice might be run within test environments, and might be run within production environments if deemed necessary. Cumulative performance overhead is less than 4% when all advice of this type is enabled.
- High: Advice impact is high or unknown. Advice might be run during problem determination tests and functional tests. It is not run in production simulation or production environments unless deemed necessary. Cumulative performance overhead might be significant when all advice of this type is enabled.
Advice status
Whether the advice is stopped, started, or unavailable.
The advice status has one of three values: Started, Stopped or Unavailable.
- Started: The advice is enabled.
- Stopped: The advice is not enabled.
- Unavailable: The advice does not apply to the current configuration, for example, persisted session size advice in a configuration without persistent sessions.
