Resolution: Fixed
> DUCC SM should support timestamps to identify idle services

> Key: UIMA-3704
> URL: https://issues.apache.org/jira/browse/UIMA-3704
> Project: UIMA
> Issue Type: Improvement
> Components: DUCC
> Affects Versions: 1.1.0-Ducc
> Reporter: Jim Challenger
> Assignee: Jim Challenger
> Priority: Minor
> Fix For: 1.1.0-Ducc
>
>
> The Service Manager's ping/monitor protocol should support a mechanism to
> provide identification of services that are started and using resources, but
> which have been idle for a "long time". The mechanism should enable
> identification of idle services and a mechanism to turn off the services
> under site policies.
> The proposed mechanism is for the ping/monitors to support a "last use"
> timestamp which indicates the last apparent use of the service. Display
> mechanisms such as the web server would use this to identify unused or
> lightly-used services.
> The mechanism also should enable ping/monitor support to automatically stop
> idle services. The Service Manager's start-by-reference mechanism is then
> used to start the service if some job later needs the service, with the only
> loss being the time needed to initialize the service.
> The mechanism should also enable the ping/monitor to re-enable the service's
> persistent running state if it determines this is needed.
> The proposed mechanism for this second step is to allow the ping/monitor to
> enable or disable the service's "autostart" flag.
