Description of problem: Error messages displayed in GUI don't provide enough detail. Steps to Reproduce: 1. try to perform an action that fails (like running GC) Actual results: Vague error message Expected results: Error message provides enough detail to diagnose problem. Possibly stack trace, since Thermostat is supposed to be used by people that have at least some basic understanding of Java. Additional info: See atatchements.

Rest of error messages is not better. I see "Thermostat failed connect to data collector." What does it mean? Also if I try to click "Configure" there is pre-filled "Storage URL", but also "User Name" and "Password". Username for Thermostat? Where do I create it?
(In reply to Marcela Mašláňová from comment #3) > Rest of error messages is not better. I see "Thermostat failed connect to > data collector." What does it mean? Agreed. We need to do better than this. As far as your "failed to connect to data collector" message is concerned please see also: http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=1572 > Also if I try to click "Configure" there is pre-filled "Storage URL", but > also "User Name" and "Password". Username for Thermostat? Where do I create > it? For mongodb:// connection URLs empty username/password should be sufficient. As far as http:// URLs are concerned that's a bit of a different story.
This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
(In reply to Mikolaj Izdebski from comment #0) > Description of problem: > Error messages displayed in GUI don't provide enough detail. > Steps to Reproduce: > 1. try to perform an action that fails (like running GC) I'd like to clarify one important point. Thermostat is a distributed instrumentation and monitoring solution. Thus what runs all-local in some setup runs on different hosts in others. Example: Host A runs agent. Host B runs gui. So performing GC means thermostat connecting to host A and asking the thermostat agent there to perform an action on behalf of user of gui on Host B. > Actual results: > Vague error message > > Expected results: > Error message provides enough detail to diagnose problem. Possibly stack > trace, since Thermostat is supposed to be used by people that have at least > some basic understanding of Java. Providing stack traces is not a good idea for various reasons (information disclosure, extra network traffic for stack trace delivery, etc). So what we could do is adding a note "Please see agent logs for details". Not sure if adding this will add much value, though.
