"some service might log errors"?<br>
<br>
Do we have a solid use case? I'd like to understand what this is
for.<br>

I guess I should be more clear about what I don't understand. I
take it that this proposal wants to gather the boot errors so they
can be accessed by some other process? What would the process be
able to do with the information?<br>
<br>
If the purpose is to let users see the errors then that is already
achieved by reading the log. So I take it that the use cases are
not user-centric?<br>

<pre wrap=""># Ability to read boot errors via WildFly Management APIs
Tracked by <a moz-do-not-send="true" class="moz-txt-link-freetext" href="https://issues.jboss.org/browse/WFLY-543">https://issues.jboss.org/browse/WFLY-543</a>
Use Cases
---------
If a server starts but reported errors during boot, there is no way to access the error data via the Management API and users are reduced to
searching the logs.
This information needs to be captured and stored for later reporting.
If some problem happens that gets logged at boot but somehow doesn't become visible to the management layer, that's out of scope. A problem
getting logged but not becoming visible would basically mean some runtime service logged an error but the error didn't prevent the start of
the service.
Implementation
--------------
Create a new sub resource of core-service=service-container because it has the ability to dump services, thus having all the services boot
errors and missing dependencies near seems like a good place.
thus we would have :
core-service => service-container {
boot-errors => {
failures => {
service-name => stackTrace;
....
}
missing-deps => {
... list of missing dependencies as String
}
}
}
This structure is based on the structure of the failure description returned during verification when starting a service.
All these informations should be collected in the ModelControllerImpl.
This resource would have restricted access of course.
What do you think?
Emmanuel
