Monasca/Logging

This page documents the Monasca Logging solution that is in progress.

Monasca Agent

Needed functionality.

OpenStack Hypervisor/VM Monitoring

The Agent should monitor each created VM (in detail)

• Install agent automatically on each created VM.

Metrics as well as logs can be forwarded to Monasca.

The Agent should monitor each created VM (basic metrics like CPU, RAM)

Metrics only!

Sources:

• Nova

Supported by agent?

• KVM

Supported by agent?

• VMware vSphere

vSphere is not supported by agent. A new plugin must be developed (blueprint...).

• VMware ESXi

Probably not supported by agent?

User:

• OpenStack administrator
• OpenStack user (multi tenancy! Can agent add the tenant ID per VM?)

Hypervisor --> Nova --> Ceilometer --> Monasca-ceilometer-plugin --> Monasca

Metrics only!

• KVM

KVM sends data to Nova, but Ceilometer (currently?) doesn't poll that data. Monasca-ceilometer-plugin is not in "product status", that means no data forwarding to Monasca.

• VMware vSphere

Although Nova provides support for VMware vCenter Server, Ceilometer does not. It does not collect metrics of virtual machines deployed on VMware virtualization platform. It will be necessary to extend this support in Ceilometer. The aim is to implement a polling agent that queries samples from VMware vCenter Server.

Collect and forward Log Data

The agent should be extended to collect log data and forward them to the Monasca Log API.

Log Management Backend/Server

Integrate ELK stack into the existing Monasca architecture.
