Cassandra: Administration and Monitoring - Beginning Apache Cassandra Development - page 241

There are many monitoring tools to analyze data and Cassandra's characteristics. A
few of the popular ones are

• Helenos

• JConsole

• nodetool

• DataStax DevCenter and OpsCenter

We have already discussed how to monitor and perform logging using JConsole in
Chapter 1 (please refer to the “Managing Logs via JConsole” section). Chapter 10 cov-
ers more about various Cassandra utilities, including nodetool . It is primarily used
for Cassandra monitoring and including other operations, some of which we have used
earlier in this chapter, like removenode and refresh .
In this section, we will discuss Helenos and the DataStax DevCenter and
OpsCenter for general monitoring.
