Summary: DUCC Web Server (WS) display of Services State and Start
Start w/hovers
Key: UIMA-4007
URL: https://issues.apache.org/jira/browse/UIMA-4007
Project: UIMA
Issue Type: Improvement
Components: DUCC
Reporter: Lou DeGenaro
Assignee: Lou DeGenaro
Priority: Minor
Fix For: 1.1.0-Ducc
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
