> DUCC Service Manager - parameterize pingers
> -------------------------------------------

> Key: UIMA-3011
> URL: https://issues.apache.org/jira/browse/UIMA-3011
> Project: UIMA
> Issue Type: Improvement
> Components: DUCC
> Reporter: Jim Challenger
> Assignee: Jim Challenger
> Fix For: 1.0-Ducc
>
>
> Currently SM sets state of a service to "healthy" if any response is received
> from the ActiveMq MBean for a queue (as well as if get-meta to the service
> works), and "unhealthy" otherwise.
> Better would be if some reasoning is done on the queue statistics from
> ActiveMQ. This is somewhat subtle as many things need to be taken into
> consideration to determine if a service is "healthy".
> For the moment, we will use the single heuristic, "is the queue depth too
> big" to better draw attention to *potential* (but maybe not actual) problems
> and defer more complete analysis to a later time.
