Heat-manage service list¶

https://blueprints.launchpad.net/heat/+spec/heat-manage-service-list

Adds the ability to heat-manage command to list the running status of heat-engines deployed in a given cloud environment.

Problem description¶

In a given enterprise cloud environment, Heat to support horizontal scaling, multiple heat-engines will be deployed and executed. Once these engines are deployed on multiple hosts, there is no way an admin can find these heat engines details like

what is the node on which heat engine is running,
what is the running status of each engine.
How long the heat-engines are running successfully.

Proposed change¶

Heat already provides heat-manage command to take care of the database syncing and archiving. As part of this blue print, ‘service list’ is added to provide the following details:

Heat-engine node name
Heat-engine running status
Heat-engine host (message queue)
Heat-engine last updated time of running status.

Alternatives¶

None
