JProbe pricing from http://www.sitraka.com/software/jprobe/pricing.html:On the other hand, I've also heard tools in the JProbe family, although very good, can be quite expensive... If indeed there's a substantial price difference between Clover and JProbe Coverage, it then all depends on the price one puts on dynamic runtime instrumentation...So does anyone know the full price for a single license of each of these tools?
JProbe Coverage(Windows only): US$649, GSS Purchase US$200, GSS Renewal US$200 (GSS=Gold Subscription with Support).
And you can also get the whole JProbe Suite (Profiler, Memory Debugger, Coverage, Threadalyzer) for US$1999 which includes GSS.
You can get an evaluation version of the whole JProbe suite at:

Clover Pricing from http://www.thecortex.net/clover/purchase.html:
Single Developer License: US$125
Continuous Integration License: US$1125
The page says "Introductory Price" which suggests that the prices may increase in the future.
Another advantage of JProbe over Clover is that JProbe has been around for a lot longer and is more mature product. Clover, on the other hand, seems to have only come into existence in May.
And personally, I'd like to know *how* JProbe Coverage does runtime instrumentation... I can see only two ways to do it, with are thru either a custom classloader, and that requires an app that does not break when run under such a custom classloader (!), or thru a custom JVM, which I would be very wary off.
JProbe uses JVMPI, the JVM Profiling Interface.
It's all in the elbow.Or is there a third way I didn't envision, or is it simply magic???
While I'm about it, I might as well plug PerformaSure which is another Sitraka product for measuring the performance of J2EE systems at runtime across multi-tier systems. It's the product that I work on at Sitraka, and personally, I think it's very cool. Check it out: http://www.sitraka.com/software/performasure/
Who? Me? Biased? Nah...
