Ceilometer/MonitoringPhysicalDevices

Monitoring Physical Devices

Goals

It should be possible to monitor physical devices in the OpenStack environment. The monitored devices are:

• the physical servers on which Glance, Cinder, Quantum, Swift, Nova compute node and Nova controller runs
• the network devices used in the OpenStack environment (switches, firewalls ...)

High Level Description

There is a new Ceilometer agent needed to achieve this. This agent should run on every physical OpenStack server. To collect data there should be a way to define and support plugins to collect the data(SNMP, Proc, IPMI ...). For example, to monitor network devices we can simply add and configure a SNMP extension on any physical OpenStack server.
