For those of you that would like to graph the hadoop JMX variables with cacti I have created cacti templates and data input scripts. Currently the package gathers and graphs the following information from the NameNode:
Blocks Total Files Total Capacity Used/Capacity Free Live Data Nodes/Dead Data Nodes Obligatory Screen shot http://www.jointhegrid.com/svn/hadoop-cacti-jtg/trunk/doc/cacti-hadoop.png Setup instructions here: http://www.jointhegrid.com/svn/hadoop-cacti-jtg/trunk/doc/INSTALL.txt Project Trunk: http://www.jointhegrid.com/svn/hadoop-cacti-jtg/trunk/ My next steps are creating graphs for other hadoop components (DataNode RPCstats). If you want to hurry this process along drop me a line for extra motivation :) Edward
