Splunk: HDFS Capacity N/A

Question

I installed splunk to monitor and analyze hadoop jobs. After I installed splunk core and splunk hadoop app in Jobtracker, forwarder and TA on other nodes, the HDFS capacity and slots capacity shows N/A in Utilization section. any idea of possible causes?

Thank you

Answer 1

The HDFS and Slots showed N/A because the metrics were not enabled and Splunk didn't get the necessary information about HDFS capacity.

Here's what I did.

1. configure hadoop to send metrics http://docs.splunk.com/Documentation/HadoopOps/latest/HadoopOps/SplunkTAforHadoopOps#Hadoop_metrics
2. configure splunk forwarders to monitor the output. http://docs.splunk.com/Documentation/HadoopOps/latest/HadoopOps/SampleHadoopinputs.conffiles
