I'm trying to tie Hadoop into Cacti (following the steps mentioned on http://www.jointhegrid.com/svn/hadoop-cacti-jtg/trunk/doc/INSTALL.txt) and have two issues:
1. After all's done, images having the axes of the graphs for the namenode metrics show up but there is no data there. The csv file has "NaN" as the values for each field. I'm able to get the metrics through JConsole. 2. For the Datanode graphs, it asks for JMXObjectName. Where do I get those from?
