#Introduction

Monitoring applications in clojure based on clojure-control.

#Leiningen dependency

[clj.monitor "1.0.0-SNAPSHOT"]

#Getting started

Use clj.monitor in your clojure ns:

	 (ns clj.monitor.example
         (:use [clj.monitor.core]
                  [control.core]
                  [clj.monitor.tasks]))

First,we define a cluster using clojure-control defcluster:

	 (defcluster mysql
	    :clients [{:user "deploy" :host "mysql.app.com"}])

Second,we define a monitor for mysql cluster:

    (defmonitor mysql-monitor
	    ;;Tasks to monitor mysql,we just ping mysql
	    :tasks [(ping-mysql "root" "password")]
		;;Mysql clusters for monitoring
		:clusters [:mysql])

The mysql-monitor try to ping mysql with root and passowrd,and execute the task on mysql cluster.

At last,start the monitors:

    (start-monitors
         :cron "* 0/5 * * * ?"
         :alerts [(mail :from "alert@app.com" :to "yourname@app.com")]
         :monitors [mysql-monitor])

If pinging mysql fails,it will send an alert email to address yourname@app.com from alert@app.com.Monitors will run every five minutes set by * 0/5 * * * ? -- a crontab-like string using Quartz.
