Edit chart - No numeric metrics available!

[davsclaus]

When trying to edit the charts for Camel plugin, then I get that information all the time.
I think we had that issue in the past as well.

See screenshot.

hmmm - seems to work here. Wonder if its browser related?

For me it only works the first time you click edit chart. Every other time it displays the "No numeric metrics available!" message.

I wonder if its to do with query arguments on the URL hanging around. Which URL does it not work on? Any chance you could post a URL that doesn't work?

[jstrachan]

Ah yeah - I think thats the issue - if you chart 1 mbean, then go to a completely different mbean that doesn't have any of the old attribute names, then it thinks there's no attributes to view any more (as none of them are valid).

Lemme try fix...

[jstrachan]

Having said that - even in this case, I can then click on the Edit Chart link and pick whatever attributes I want again.

Its a bit tricky knowing when to trash the attr / el query attributes really. Maybe we should do that whenever we change mbean selection to a different type or something?

[janstey]

Not sure when to discard though args :-) When I load a different tab (eg. ActiveMQ) and go back to Camel I can then again view the edit chart page. If it helps, I'm running this on the JBoss Fuse 6 GA kit and loaded an example + hawtio like so:

osgi:install -s fab:mvn:org.jboss.fuse.examples/jms/6.0.0.redhat-024
features:addurl mvn:io.hawt/hawtio-karaf/1.2-SNAPSHOT/xml/features
features:install hawtio

Any chance you could copy and paste the URL here when you're on a page that doesn't work? So we can work out bad combinations of URLs to test against?

[jstrachan]

BTW a little secret trick I use now and again; to reset all the query arguments, click on the 'hawtio' link on the top left of the nav bar :)

[janstey]

Looks the same to me:

good URL: http://localhost:8181/hawtio/index.html#/jmx/chartEdit?tab=camel&nid=root-org.apache.camel-bender%2F234-jms-example-context-routes-%22file-to-jms-route%22
bad URL: http://localhost:8181/hawtio/index.html#/jmx/chartEdit?tab=camel&nid=root-org.apache.camel-bender%2F234-jms-example-context-routes-%22file-to-jms-route%22

Nice trick, will keep that one handy :-)

[jstrachan]

OK I"ve a partial fix for this now I think; at least in the case where the attr=Foo attribute names don't match anything on the current MBean we ignore them and chart all the attributes. The Edit Chart view was broken a little bit due to the Route nodes in the Camel tree having children as well (so they were kinda treated as a folder of mbeans). Fixed that too now

[jstrachan]

I think I've fixed this now; let me know if it doesn't work for you. Tried all the permutations I could think of; we basically now try to ignore duff attribute selections from some mbeans being used to chart other mbeans.

Incidentally if you can reproduce some oddness, it'd really help knowing which URLs go wonky; i.e. which selections of things break (folders or mbeans) and which parameters were being passed in (e.g. the 'el' and 'att' query attributes).

Fingers crossed this really is fixed now though! :)

[janstey]

Yep you fixed it. Works perfectly now :-) Thanks!

[jstrachan]

Awesome - phew! :)
