> 1. How is State value calculated?
> case 1) no alert: value = meta.service-state
> case 2) alert: value = meta.service-state+"Alert"
> alert in effect when:
> case 1) meta.submit-error is non-empty
> case 2) (meta.service-healthy is false or meta.service-alive is false)
> and meta.ping-active is true and state is { Available, Starting, Waiting,
> Initializing, Stopped }
> There should be no alert for
> Initializing, Starting, and Stopped as a function of service-healthy because
> it is a function of the pinger, which can only be running, or trying to run,
> in Available and Waiting.
> Discussion): The cases Starting, Initializing, and Stopped are covered by
> cases 1 and/or the StartMode.disabled flag. Because the pinger is not
> running service-healthy is undefined.
> case 3) meta.ping_active is false and state is { Available, Waiting }
> 2. How is State hover calculated?
> hover = ""
> if meta.service-state == "Waiting" && meta.ping-active is true hover
> += "Pinger is starting"
> if meta.service-state == "Waiting" && meta.ping-active is false
> hover += "Pinger is unable to start" (or your preferred language)
>
> Discussion: Waiting+false can happen if the service is ok but the
> pinger is broken. We don't want to stop the service processes for lots of
> reason but we want it clear that the pinger is not coming back without manual
> intervention.
> if meta.service-state == "Available"
> && meta.ping-active is false hover += "Pinger is not active"
> if(meta.submit-error is non-empty) hover += meta.submit-error
> if(meta.service-statistics is non-empty) hover +=
> meta.service-statistics
> if meta.service-state in (Available, Waiting) &&
> meta.service-healthy is false && meta.ping-active is true hover += "Pinger
> reports poor health" (or your preferred language)
> if meta.service-state in (Available, Waiting) && meta.service-alive
> is false && meta.ping-active is true hover += "Service not responding to
> pinger" (or your preferred language)
> 3. How is Start value calculated?
> Answer: according to the table given by Jim/eae.
> public StartState getStartState() {
> StartState retVal = StartState.Unknown;
> if(isAutostart()) {
> retVal = StartState.Autostart;
> }
> else {
> int ordinality = getStateOrdinality();
> if(ordinality > 3) {
> if(isReference()) {
> retVal = StartState.Reference;
> }
> else {
> retVal = StartState.Manual;
> }
> }
> else if(ordinality < 4) {
> retVal = StartState.Stopped;
> }
> }
> return retVal;
> }
> A second line comprising "Disabled" is added whenever meta.enabled is
> false
> 4. How is Start hover calculated?
> A hover is added over "Disabled" whenever:
> if(meta.disable-reason is non-empty) hover = meta.disable-reason
