Cassandra number of read and write operations in a given time period

Write a Review

Description:

This Plug-in monitors Cassandra number of read and write operations in a given time period, i.e. Read operations per second / write Operations per second.

it fetches WriteOperations or ReadOperations from Nagios JMX plugin and stores the values with timestamp in a log file at /tmp directory, and parses this log file to create the Read/write per second value.

####Sample Log entries###
cat /tmp/Cass_ReadOperations.log
1323353650=JMX CRITICAL ReadOperations=0
1323353710=JMX CRITICAL ReadOperations=120

so the Read per second would be (120-0)/(1323353710-1323353650) i.e 2 per Second.

This take three parameters as input 1) Option i.e. Read operations or write Operations and Warning and Critical Values.
