HP P6000 Performance Advisor Software - Manual (Page 38)

A custom threshold profile is useful when you want to monitor the performance of objects for
different counters, or monitor an object's performance for a specific counter. In contrast to a
threshold profile, a custom threshold profile does not have a name and appears as Custom for the
object for which it is configured. It provides data for the past 24 hours only.
Factors for setting threshold levels
Expected performance of a storage system depends on multiple factors, such as:
•
Configuration of the storage system (number and capacity of disk drives in the disk groups,
rotational speed of drives, and so on)
•
RAID levels of the virtual disks
•
Intensity and pattern of currently running I/O workload (sequential or random, read-write
ratio, and size of I/O transfers)
•
Other storage background activities
In addition, view the current performance counter values to determine appropriate threshold values
for your storage system.
Threshold alarm email notifications
The following charts illustrate the threshold alarm email notification behavior when the performance
data exceeds the minor or major threshold level.
Notify starting at minor threshold level
Notify starting at major threshold level
NOTE: If you want to receive notification at a minor threshold level, and the performance data
of the object reaches or exceeds the major threshold level, only one threshold email alarm
notification is dispatched at the major threshold level.
