Summary
Multiple publishers in ceilometer transform collected measurements into different format, like meter, metrics etc, and publish to different target, like data storage, synaps etc, through different conduit, like rpc, UDP etc.
To support different requirement from different publishers, a set a transformers are orgnized as pipeline, to transform the data from counter to meter, metrics etc.
Release Note
Rationale
User stories
Disk usage data collected from hypervisor are published to ceilometer collector as meter through message bus, and published to synaps as metrics through PutMetricData.
Metering system publish network usage data as per-vnic usage information, while CW publish the network usage data as a whole.
Assumptions
Design
This is just one possible design for this feature (keep that in mind).
Implementation
This section should describe a plan of action (the "how") to implement the changes discussed. Could include subsections like:
UI Changes
Should cover changes required to the UI, or specific UI that is required to implement this
Code Changes
Code changes should include an overview of what needs to change, and in some cases even the specific details.
Migration
Include:
- data migration, if any
- redirects from old URLs to new ones, if any
- how users will be pointed to the new way of doing things, if necessary.
Test/Demo Plan
This need not be added or completed until the specification is nearing beta.
Unresolved issues
This should highlight any issues that should be addressed in further specifications, and not problems with the specification itself; since any specification with problems cannot be approved.
BoF agenda and discussion
Use this section to take notes during the BoF; if you keep it in the approved spec, use it for summarising what was discussed and note any options that were rejected.
