@ANierbeck How to access the Dashboard GUI?

ANierbeck commented 7 years ago

@anhldbk ... could be found in the sources ;) https://github.com/ANierbeck/Karaf-Vertx/commit/09ecf5e15c9e5cb4a4908c82cf18e795e44a32de#diff-bccf593ea77a28e62815e7e3a9c351acR105 it's /metrics

@ANierbeck When I access http://localhost:8080/metrics/index.html, I've got an exception of:

Caused by: java.nio.file.FileSystemException: .vertx/file-cache-b968ce38-5354-4cf7-aa16-08bb5b982ab4/10.0/webroot/index.html: Not a directory

The problem is webroot is not properly extracted to directory .vertx/file-cache-b968ce38-5354-4cf7-aa16-08bb5b982ab4/10.0. I solved by manually copying webroot to the directory.

Would you please tell me what wrong is?

In file MetricsDashboard.java, currently we have:

// line 90
router.route("/*").handler(StaticHandler.create("webroot", this.getClass().getClassLoader()));

I modified to:

router.route("/*").handler(StaticHandler.create().setWebRoot("we‌broot"));

@ANierbeck Should I make a PR against this issue?

How do you use it? Inside an OSGi environment, in that case you should keep the classloader part :)

@ANierbeck I just entered bin/karaf and navigated to /metrics
