Java Simon - Simple Monitoring APIJava 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. Do you like Java Simon? For three years we've developed it without asking for anything. However if you want to help us or just cheer us up click the button bellow. Maybe we will buy a beer for it, maybe we will use it to pay the fee for the javasimon.org domain. We put a lot of effort in it already - and we plan to put some more still. NewsJanuary 1st, 2012 - Happy New Year with version 3.1.0!New version was release with a lots of improvements - check the list. Besides some polishing, these are the most important:
December 31st, 2011 - new member, new "homepage", old logoI decided to move our homepage to Google+ Page created for Java Simon: http://gplus.to/javasimon The reason is, that it's not so easy to update Webnode page and we don't need any big page that partially collides with the project page anyway. Soon the domain javasimon.org will point on the Google+ page and our "homepage" will go down. More importantly - we have a new commiter on board. Month ago I didn't know he existed, but after the last month I decided to strengthen our lines - welcome Gerald, I hope it will all work well. :-) Lastly - we might need a new logo. Do you want to try it? There is no price in this competition. Any attempt will be shown though and the one we like the most will become our official logo. Rules for the logo are quite simple:
October 11th, 2011 - Version 3.0I honestly can't believe it, but I won my long fight with Maven Release plugin! Result is our new major version with the following important changes:
Why Java Simon?Back in 2008 we wanted to use something like JAMon for our products originally, but we lacked two important features:
Simon API gives you a better control over all those monitors in your big - possibly Java EE - application. Simons are organized in a hierarchy similar to what you can see in java.util.logging API. Simons can be disabled which minimizes their overhead influencing your application. These operations can be performed on the whole subtrees of Simons which makes partial application monitoring easier. See SimonHierarchy for more. Simon measures times in nanos - and since 2008 nanos have been getting better with every OS and JDK release. Believe it or not it can make the difference on current very fast machines. See SystemTimersGranularity page for more. Future plansOur future goals include (the later goals are in a more distant future):
BTW: Where and when we will be there depends on your feedback as well. :-) Do you have something to tell us?So tell us! Visit our Google Group (preferably) or file an issue, whatever. We can't promise to fulfill all your dreams but we want to produce the library YOU like (and so do we - of course ;-)). So if you know how to make Simon better, without making it something it is not, let us know! We want to know. |
