NagiosCassandraMonitor

======================

This project is a fork of the so-net-developer/cassandra project. 

Why

---

To provide a robust and easily extendable Nagios Plugin for monitoring Cassandra

Things that I'm doing with this project

---------------------------------------

 * Reorganizing into a Maven based project

 * Moving hard-coded strings out to property files were applicable

 * Building in unit testing for future improvements

 * Adding additional reporting capabilities

 

	

Requirements

------------

 * Java 1.6 or greater

 * Maven

 * Cassandra node (to monitor)

 * Nagios server

 

 Usage

 -----

 

 Compile  using maven:

 

 	mvn assembly:single

 	

 Copy jar file to your Nagios libexec folder

 

 	check_cassandra_node.sh    

 

 Available Tasks (not case sensitive):

 

 	numnodes

	availablenodes

	deadNodes

	deadNodeList

	status

	token

	readlatency

	writelatency

	

Check number of nodes:

	//Warn if fewer than 4 nodes, critical if 3 nodes or fewer, OK otherwise:

	check_cassandra_node.sh hostname numNodes -w4: -c3:

	

check what nodes are available:

	

	//Returns: OK - LIST OF NODES

	check_cassandra_node.sh hostname availableNodes
