Support for PowerVM Performance Monitoring
|
|
==========================================
|
|
|
|
The IBM PowerVM hypervisor provides virtualization on POWER hardware.
|
|
PowerVM customers can see benefits in their environments by making use
|
|
of OpenStack. This project implements a Ceilometer-compatible compute
|
|
inspector. This inspector, along with the PowerVM Nova driver and Neutron
|
|
agent, provides capability for PowerVM customers to natively monitor
|
|
utilization and statistics for instances running on OpenStack-managed systems.
|
|
|
|
|
|
Problem Description
|
|
===================
|
|
|
|
PowerVM supports a variety of performance monitoring interfaces within
|
|
the platform, providing virtual machine and system monitoring data.
|
|
Ceilometer-powervm implements a Ceilometer-based compute inspector for the
|
|
PowerVM hypervisor.
|
|
|
|
Inspector Description
|
|
=====================
|
|
|
|
The Ceilometer compute agent provides an inspector framework that allows
|
|
hypervisors to integrate support for gathering instance statistics and
|
|
utilization details into Ceilometer. This project provides a standard
|
|
Ceilometer virt inspector that pulls its data from the PowerVM Performance and
|
|
Capacity Monitoring (PCM) infrastructure.
|
|
|
|
This inspector retrieves instance monitoring data for cpu, network, memory, and
|
|
disk usage. Interactions with PowerVM PCM occur using the PowerVM REST API
|
|
stack through `pypowervm`_, an open source python project.
|
|
|
|
This inspector requires that the PowerVM system be configured for management
|
|
via `NovaLink`_.

|
End User Impact
|
|
---------------
|
|
|
|
The users of the cloud are able to see the metrics for their virtual machines.
|
|
As PowerVM deals with 'disk buses' rather than specific disks, the hard disk
|
|
data is reported at a 'per bus' level (i.e. each SCSI or Virtual Fibre Channel
|
|
bus).
|
|
|
|
Performance/Scalability Impacts
|
|
-------------------------------
|
|
|
|
None.
|
|
|
|
Other deployer impact
|
|
---------------------
|
|
|
|
The cloud administrator needs to install the ceilometer-powervm project on
|
|
their PowerVM compute node. It must be installed on the `NovaLink`_ virtual
|
|
machine on the PowerVM system.
|
|
|
|
The cloud administrator needs to configure their 'hypervisor_inspector' as
|
|
powervm.
|
|
|
|
No other configuration is required.
|
|
|
