Enabling plugins for the WebConsole

[luis soares]

Hi guys,

Wanted to start by saying thank for JavaSimon, I've been enjoying it a lot and it was super easy to integrate in my application. The only part so far which I could not get working at all has been the plugins for the web console.

So, I have a couple of classes with stopwatches and I added the Quantiles plugin as instructed in the WebConsolePlugins wiki page (http://code.google.com/p/javasimon/wiki/WebConsolePlugins): 

- Added the init params to the JavaSimon servlet in web.xml;

- Registered the callback at construction time for one of my classes.

Now, when I go to the console, there's nothing new there. There's also no error though...

Is there anything else that needs to be done to use web plugins?

Thanks,

L.

Hi Luis,

Which variant of QuantilesCallback are you using? In 3.2 there is only Auto, in 3.3 there are Auto, Fixed and Properties variants.
If you're using the AutoQuantilesCallback there is a warmup period used to compute the best buckets size.

Look here

• http://javasimon.googlecode.com/svn/javadoc/api-3.2/org/javasimon/callback/quantiles/QuantilesCallback.html
• http://javasimon.googlecode.com/svn/javadoc/api-3.3/org/javasimon/callback/quantiles/AutoQuantilesCallback.html

Then for the WebConsole plugin, in the detail view, do you have a "Quantiles" section?

• If the section is present but empty, it's because you don't have data yet (QuantilesCallback is not present or warming up)
• If the section is not present, then your plugin is not properly registered.

To avoid warm up, you can use Fixed and Properties variants but it's not very easy to manually configure properly buckets, read:
http://javasimon.googlecode.com/svn/javadoc/api-3.3/org/javasimon/callback/quantiles/Buckets.html
to understand Buckets configuration

I'll document this a bit more.

Hope it help,
Gérald

Hi Gérald,

Thank for the info.

I found out what the problem was: when I first searched http://mvnrepository.org/ for org.javasimon artifacts, the latest version there was 3.2.1 (actually it still is). Then, on the code.google.com I saw that your latest version was 3.3.0 and I updated it on my POM *but* only for the core artifact.

So, my web.xml line including the plugin was not doing anything at all. :-$ Weird that it also didn't complain that it couldn't find that class though...

Anyways, I updated all the artifacts I was using to 3.3.0 and I can now see the Quatiles screen after clicking on any of Simons.

One more thing, should we not rely on http://mvnrepository.org/ for the latest versions available through Maven Central? Should we only look at http://code.google.com/p/javasimon ?

Thanks once again,

L.

Hi Luis

It seems you can't rely on mvnrepository.org

http://search.maven.org/#search|ga|1|javasimon

This shows 3.3.0 as the latest version - and of course you can use it
in your POMs without downloading anything. I don't know what
mvnrepository is, who is responsible for it, but it's definitely good
to know (for me) that I can't rely on it that much. :-)
