L

Live Data

The real-time data displayed in HP P6000 Performance Advisor chart (Live chart).

M

Minor and Major
threshold levels

The first and second threshold levels associated with a specific performance counter that user
selects while creating threshold profile, or plotting live chart on Dashboard. If performance data
is below the minor threshold level, the performance object with reference to the performance
counter is considered to be in a Normal state. If performance data has exceeded the minor
threshold level but still within the major threshold level, the performance object with reference to
the performance counter is considered to be in a Warning state. If performance data has exceeded
the major threshold level, the performance object with reference to the performance counter is
considered to be in a Critical state.

P

Performance
Counter

Each object type has a set of associated counters that characterize the workload and performance
metrics for all performance objects belonging to that object type. The performance of an object
is monitored for all the specific set of counters. These counters can belong to different categories
based on their units of measurements. For more information, see
