As described in Tip #1, the stack trace of the current execution can be retrieved from the current thread.

Takipi detects all exceptions and errors in your code and tells you why they happen.

It’s also worth mentioning since it’s open-source and free.

Here’s the tool set and architecture to crack it once and for all.

One software that wasn't yet mentioned is LogRhythm. When does bugfixing become overkill, if ever? How does a migratory species farm? have a peek here We did find some useful stuff in Chainsaw but then realized that we wanted Insight to be more than a log analyzer.

From a dev perspective, it means that if an exception isn’t logged, or the variable data you need to understand why it happened isn't there, no log file or analyzer in Gerardo Lastra Update: Now I understand… you meant w*, not w* obviously 🙂 http://tonytrinh.me Tony Yep, you're right. When an error does come – you need to be able to solve it right away.

Looking into hardcore JVM internals, jClarity and Plumbr are definitely worth checking out as well.

That means that extensibility also becomes complex. Another approach is to use one of the overloaded versions of Throwable.getStackTrace() that do not simply print the stack trace to standard error. by Regunath B on April 02 2008 12:06 EDT Re: Very Windows friendly! Cons This isn't really a commercial offering, and you're limited in the amount of data you can send.

GrayLog vs. A few TB log analysis can run on a laptop. Splunk’s search and charting tools are feature rich to the point that there’s probably no set of data you can’t get to through its UI or APIs. Although I agree that there is merit to not going right to the search engine for every problem, I have also been the beneficiary more times than I can recall of
