The PowerPath management pack is an MP or AKM file that monitors the installation and
operation or PowerPath, and also its paths and volumes on data networks. Using the
management pack, Operations Manager can effectively monitor PowerPath by using the
triggers, alerts, and SNMP traps.
The management pack defines the services and components of Operations Manager to be
monitored, and also consists of rules to remotely monitor the PowerPath events.
Apart from monitoring the PowerPath and the Operations Manager alerts, the
management pack also monitors connectivity. When a path or volume is unavailable for a
specified period, the management pack receives SNMP traps informing about the
disconnection.
The Operations Manager alerts are viewed from the System Center console and the SNMP
traps are viewed from an SNMP manager.
The PowerPath management pack monitors PowerPath paths and volumes, and triggers
alerts and SNMP traps based on pre-defined criterion. You can modify this criterion.
The PowerPath management pack addresses the following PowerPath states:
- PowerPath path is dead - If the path does not come back alive within one minute
(default interval), then an alert and an SNMP trap is generated with the path
information.
- PowerPath volume is dead - If the paths to the volume remain dead for more than five
minutes (default interval), then an alert and an SNMP trap is generated with the
volume information.
- PowerPath path latency threshold is exceeded - When path latency monitoring is
enabled, PowerPath measures the amount of time each I/O request takes to complete
on the selected path. If the latency threshold is exceeded, then an alert and an SNMP
trap is generated with the path, volume, and latency information.
