About Java Simon
About Java Simon API Java Simon is a simple monitoring API that allows you to follow and better understand your application. Monitors (familiarly called Simons) are placed directly into your code and you can choose whether you want to count something or measure time/duration. Main features include:… Read more
Funny nanotimer performance
We're slowly closing in with version 2 of the Java Simon and during the process I tried to test how we stand against JAMon after adding things like Callbacks. Truth is that Simon now does a bit more than before and I was curious about the impact. I compiled JamonComparison class from our examples, started… Read more
JMX and Callbacks on the way
There is a lot of work going on the project right now and I've summed it up in the mail on our google-group. We're working on JMX and also on the way how you can hook onto various events in the API via Callbacks. We also realize there is a lot of work to do in the area of charting, data analysis, .… Read more
Version 2.2 - minor extensions
Few days ago we've uploaded new Java Simon version 2.2. It's not a big one, but there were two additions into interface - first thing is Wrapping JDBC Datasource and the second is the method returning current running-for time for a Split in human readable form. The rest - along with download links -… Read more
Quiet, but not completely
It is true, we sort of put Java Simon on ice, but that doesn't mean we gave up on it altogether. Virgo has a secret plan to work on Radovan's previous Simon servlet filter and maybe we can build also some web frontend. That is if our other work duties go a bit less hectic, because right now there is… Read more
Contact Us
Contact If you want to discuss Java Simon than our Google Group mailing-list is probably the best place. The project itself (SVN, Wiki with technical content) is hosted on Google Code. Please, don't send us emails unless it's something that really can't be discussed on mailing list. Members Richard… Read more
Version 2.1 - JMX update mostly
This is a minor update of version 2 based on some user's input: added methods reset and two versions of sampleAndReset to SimonMXBean; you can now use [, ], and _ in Simon names; timestamps for 0 are formated as undef in toString methods. Check downloads on the right side of the project page, we also… Read more
Working on version 2
Based on the users' input we decided to refine few things in the interface which breaks the compatibility with the first version but brings better Java Simon to you - which is probably more important concern (while the adoption is not that massive ;-)). We started development of the next iteration that… Read more
Major changes in the core of the Java Simon v2
While there are some important extensions to the Java Simon (JMX, Spring integration, etc.) there are a few important changes in the core part of the API that are probably even more important. If you've already managed to use Java Simon 1 I strongly suggest that you use version 2 even in its alpha stages… Read more
Why to use v2-alpha instead of v1?
While the last officially released version of the Java Simon is version 2 we strongly recommend you to use version 2 even in its early alpha stage. Version 1 is not supported anymore and especially its Stopwatch behaviour changed significantly. Read more here. Most recent supported version can be found… Read more
Java Simon on Ohloh
I don't undestand what Ohloh stands for but that doesn't matter really. :-) Ohloh somehow found our project by itself and after some time of ignorance we've decided to take over and updated and cleanup the information there. So this is our project page on Ohloh! If you use Java Simon, don't be shy and… Read more
Google Group created
Thanks for initial interest - there was a great idea to settle some mailing list - so we've just created Google Group for Java Simon: http://groups.google.com/group/javasimon It should be our primary discussion site, so go ahead and ask there.… Read more
Version 2 out!
After few more fixes, some simplifications (ever used StatProcessor? it's gone!), more Javadocs and some Wiki updates (with some more ahead) we have finally released version 2 of Java Simon library. You can choose the big package with precompiled JARs, Javadocs (here online) and working Ant build -… Read more
Bugfixes in 2.1.1
Bugfix release 2.1.1 appeared on our project page, of course we recommend to use this version from now on. Otherwise nothing big is going on now. If anything is released anytime soon it will probably be Web module with web/servlet filter and some simple web console. If you have anything to contribute… Read more
Version 2.3 - Attributes for Simons!
Based on your requirements we extended Java Simon in the following way: JMX Register Callback is not final anymore You can now add your own custom "attributes" to Simons (like in Servlet request for example) Plus a few bugfixes NPE, wrong class returned and one more NPE :-) In addition to… Read more
