Check it out. <a href="http://mosquito-the-tool.blogspot.com/2007/01/mosquito-02-sneak-peek-highlighting.html">Diff pictures</a> are really cool!<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/15137671-8576061506404614800?l=randomrareposts.blogspot.com' alt='' /></div>Mikenoreply@blogger.com0tag:blogger.com,1999:blog-15137671.post-1135258568709412032005-12-22T05:28:00.000-08:002005-12-23T05:40:11.226-08:00I've just completed a <a href="http://www.bootchart.org/">bootchart</a>-like utility, for analyzing Java programs running behaviour. Here's a sample of it's output (IntelliJ IDEA compilation process):<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://photos1.blogger.com/blogger/2504/79/1600/compile.jpg"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="http://photos1.blogger.com/blogger/2504/79/400/compile.jpg" border="0" alt="" /></a><br /><br /><br />On top of it there are several memory metrics graphs, on the bottom - the most important part - threads chart. The short legend:<br /><br />- red line - thread in running state<br />- green line - thread in the other (waiting, blocked) state<br />- no line - thread doesn't exist<br />- red background - the amount of User CPU time consumed (more red = more User CPU time)<br /><br />Here's much larger chart:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://photos1.blogger.com/blogger/2504/79/1600/performance.jpg"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="http://photos1.blogger.com/blogger/2504/79/400/performance.jpg" border="0" alt="" /></a><br /><br /><br />Technorati tags: <a href="http://technorati.com/tag/java" rel="tag">java</a> <a href="http://technorati.com/tag/jmx" rel="tag">jmx</a> <a href="http://technorati.com/tag/performance" rel="tag">performance</a> <a href="http://technorati.com/tag/bootchart" rel="tag">bootchart</a> <a href="http://technorati.com/tag/intellij" rel="tag">intellij</a><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/15137671-113525856870941203?l=randomrareposts.blogspot.com' alt='' /></div>Mikenoreply@blogger.com2tag:blogger.com,1999:blog-15137671.post-1135255323196169802005-12-22T04:42:00.000-08:002005-12-23T05:40:25.340-08:00<p>The api turned out to be really usefull.
