Having completed all of the steps described in the first two posts of this series you should be able to start and use Pinpoint. To test that everything is working fine you can use the testapp web application which is part of its quickstart bundle. For this purpose you could start the collector and the web UI from the quickstart as well: %PINPOINT_HOME%\quickstart\bin\start-collector.cmd %PINPOINT_HOME%\quickstart\bin\start-web.cmd Then start the testapp application: %PINPOINT_HOME%\quickstart\bin\start-testapp.cmd Check that everything is fine connecting to the web UIs:     Pinpoint Web - http://localhost:28080     TestApp - http://localhost:28081 Start to do some actions in the testapp application and see through the web UI which information are sent to Pinpoint. Now you can profile any Java web and standalone application of yours. You need to download the agent jar in any location in the application hosting machine. Then, for standalone applications, you need to run th

This second post of the Pinpoint series covers the configuration of the HBase database where the monitoring data are written by the collector and from which they are read by the web UI. I did the first evaluation of Pinpoint on a MS Windows machine, so here I am going to cover some specific installation details for this OS family. For initial evaluation purposes a standalone HBase server (which runs all daemons within a single JVM) is enough. Database installation Here I am referring to the latest stable release (1.2.4) of HBase available at the time this post is being written. This release supports both Java 7 and Java 8: I am referring to Java 8 here. Cygwin isn't going to be used for this installation purposes. Of course you start downloading the tarball with the HBase binaries and then unpack its content. Rename the hbase-1.2.4 directory to hbase . Set up the JAVA_HOME variable to the JRE to use (if you don't have already done it in this installation machine). E

I started a journey evaluating Open Source alternatives to commercial New Relic and AppDynamics tools to check if some is really ready to be used in a production environment. One cross-platform Application Performance Management (APM) tool that particularly caught my attention is Pinpoint . The current release supports mostly Java applications and JEE application servers and provides support also for the most popular OS and commercial relational databases. APIs are available to implement new plugins to support specific systems. Pinpoint has been modeled after Google Dapper and promises to install agents without changing a single line of code and mininal impact (about 3% increase in resource usage) on applications performance. Pinpoint is licensed under the Apache License, Version 2.0 . Architecture Pinpoint has three main components:  - The collector: it receives monitoring data from the profiled applications. It stores those information in HBase .  - The web UI: the front-end
