You&#39;ll likely won&#39;t be able to get to its UI and if it records any data for future viewing, it&#39;s likely that some information won&#39;t be recorded at all during the problematic period.<br />2) I didn&#39;t find any information on how this plugin works in clustered environment, so I&#39;m assuming that the monitoring is done on per JVM basis and can be viewed only by logging to all of the individual nodes. In other words there is no central management or aggregation going on.<br /><br />The Adaptavist came up with something very interesting, but from what I&#39;ve seen it&#39;s again something suitable only for smaller non-clustered instances.<br /><br />However! Going from what they have to a standalone product that runs outside of the Confluence VM and gathers data from several nodes should not be that difficult. Especially if they are really reusing the VisualVM apis. If they added data archival, aggregation and some fancy statistics they would have a really slick version of what my team build for our internal monitoring.<br /><br />/iIgor Minarhttp://www.blogger.com/profile/03520548417275543432noreply@blogger.comtag:blogger.com,1999:blog-6406593750327945950.post-37849249304564249852010-07-31T04:07:50.352-07:002010-07-31T04:07:50.352-07:00Igor,<br /><br />I just wanted to say that I&#39;m really enjoying this blog series, and I&#39;m learning a lot! Thanks for writing all of this up.<br /><br />I was also wondering if you&#39;ve tried Adaptavist&#39;s Visual VM plugin for confluence: https://www.adaptavist.com/display/ADAPTAVIST/2010/06/10/Adaptavist+announce+Visual+VMm+plugin<br /><br />I&#39;ve just played with a little bit, but it&#39;s pretty nice. It puts some of the monitoring graphs from Visual VM right into a web page in the Confluence admin console.<br /><br />Anyway, I&#39;ll keep making my way through the rest of the posts you&#39;ve made already, and I&#39;m looking forward to what comes next.<br /><br />-- TimTim Moorehttp://www.blogger.com/profile/00144965624247394516noreply@blogger.com
