This document discusses the architecture of OpenTSDB and provides instructions for setting up and using OpenTSDB to collect CPU metrics from a host. It describes: 1) The main components of OpenTSDB including the TSD, HBase, and Hadoop. 2) How to start and stop OpenTSDB by starting/stopping TSD, HBase, and Hadoop. 3) A sample scenario of collecting CPU load average metrics from a host and inserting them into OpenTSDB using a script to post metrics to the TSD socket.
![Sample scenarioThis scenario is about how to insert CPU metrics of a host to opentsdb:Add these metrics to hbase first:./src/tsdbmkmetricproc.loadavg.1m proc.loadavg.5m 2.
