[Design of JBoss jBPM] - Re: Analytical and operational dashboards

Roland actually posted some examples that are close to what I mean: anonymous wrote : | If the number of open goes up, but the average also goes up and the average of a processdef. (including stdv) also goes up, then there most likely is a bottleneck in an external actor (system or human) being used. | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4185242#4185242 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4185242

anonymous wrote : | Are there any plans to support business indicators (KPIs)? | If they get too domain specific, no. At least not in the beginning. A good dashboard is always customized to the users needs. I am talking about is information the can be derived from default BPM terms, because we are not offering a lot of customization in the beginning. Don't underestimate it though. People have the capabilities to read "between the lines". What you described with order example, can be derived from non domain specific figures as well. IMO "outstanding orders" can be as well expressed as a particular derivation or exception in the process execution without being to much tight to that particular domain. The goal should be that people with specific knowledge are able to "recognize" patterns that put them in alert state or at least raise their interest.

[Design of JBoss Profiler] - Re: OutOfMemory Exception Generating reports

by andy.miller＠jboss.com

The size of the data is just under 500MB. I even cut down my run from 75 clients to 10, so that it would be much smaller. Anyway, any good ideas about how I could get it to you. Certainly, I can't just e-mail it with it size and all.

I have commited a fix for this against svn commit -m JBMICROCONT-374. I still need to figure out how to test this...

[Design the new POJO MicroContainer] - Re: ClassLoader injection Scope issue

"alesj" wrote : "adrian(a)jboss.org" wrote : | | Neither of them work. See my comment about needing the className -> class HACK | I see. | What to do then? | Adding another hack to existing hack? :-) | I think the closet you can get is: 1) Add the CLASS scope as we described above, but... 2) If bean.getClassLoader() == null add the real class to the CLASS scope level using the deployment classloader to load the class 3) otherwise just use the class name. Basically this means that if the bean is not using the deployment classloader then unit.getMetaData() can't see the class annotations (ClassMetaDataRetrievalFactory will return null for that metadata loader). That seems like a fair restriction for this edge case and doesn't require the HACK in the deployer's handling of scopes. One change though is that it will be trying to load the bean class when it creates the components. So it will be reporting an error in that earlier. You need to make sure this error is understandable. If you don't like this change, then you would have to introduce the HACK to make it lazily load the class and update the scope key when getMetaData() is first used.
