Monasca/Logging
This page documents the Monasca Logging solution that is in progress.
Note:
Currently we only have this page to discuss our proposals. For that reason some "metric related stuff" can be found here too. We will move or remove it whenever the discussion is finished.
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.
