使用openNMS监控JBoss系统状态

openNMS一共有两种JMX agent，一种是 jmx（或叫做jboss4）plugin，另一种是JSR160 Plugin。
尽管openNMS提供了监控jboss的Jboss* Plugin，但是只限与jboss3.2或者jboss4.x，所以本文主要描述如何通过JSR160 Plugin来收集jboss返回的状态参数，从而达到监控jboss的目的。

一，配置capsd
打开 $OPENNMS_HOME/etc/capsd-configuration.xml, 添加如下代码：

	<protocol-plugin protocol="JBoss" class-name="org.opennms.netmgt.capsd.plugins.Jsr160Plugin" scan="on" user-defined="false">
	  <property key="port" value="1090"/>
	  <property key="type" value="default"/>
	  <property key="protocol" value="rmi"/>
	  <property key="urlPath" value="/jmxconnector"/>
	  <property key="retry" value="2"/>
	  <property key="timeout" value="2000"/>
	</protocol-plugin>

二，配置 poller（轮询）
打开 $OPENNMS_HOME/etc/poller-configuration.xml，添加如下代码：

	<service name="JBoss" interval="300000" user-defined="false" status="on">
			<parameter key="port" value="1090"/>
			<parameter key="retry" value="2"/>
			<parameter key="timeout" value="3000"/>
			<parameter key="rrd-repository" value="C:/PROGRA~2/OpenNMS/share/rrd/response"/>
			<parameter key="ds-name" value="jmx"/>
			<parameter key="friendly-name" value="jboss"/>
	</service>

在poller-configuration.xml的末尾，加上：

<monitor service="JBoss"  	class-name="org.opennms.netmgt.poller.monitors.Jsr160Monitor" />

三，配置collected-configuration.xml
打开 $OPENNMS_HOME/etc/collected-configuration.xml,配置如下：

<package name="jboss">
	   <filter>IPADDR IPLIKE *.*.*.*</filter>
	   <include-range begin="1.1.1.1" end="254.254.254.254"/>
	   <service name="JBoss" interval="300000" user-defined="false" status="on">
		 <parameter key="port" value="1090"/>
		 <parameter key="retry" value="2"/>
		 <parameter key="timeout" value="3000"/>
		 <!--
		  <property key="username" value="<username>"/>
		  <property key="password" value="<password>"/>
		 -->
		 <parameter key="protocol" value="rmi"/>
		 <parameter key="urlPath" value="/jmxconnector"/>
		 <parameter key="ds-name" value="jmx"/>
		 <parameter key="friendly-name" value="jboss"/>
		 <!-- This must match the collection name in the jmx-datacollection.xml that defines the set of mbeans you want -->
		 <parameter key="collection" value="jboss"/>
	   </service>
	 </package>

	<collector service="JBoss"          class-name="org.opennms.netmgt.collectd.Jsr160Collector"/>

四，配置jmx-datacollection-config.xml
打开 $OPENNMS_HOME/etc/collected-configuration.xml,配置如下：

<jmx-collection name="jboss">
        <rrd step = "300">
            <rra>RRA:AVERAGE:0.5:1:8928</rra>
            <rra>RRA:AVERAGE:0.5:12:8784</rra>
            <rra>RRA:MIN:0.5:12:8784</rra>
            <rra>RRA:MAX:0.5:12:8784</rra>
        </rrd>
      
        <mbean name="DefaultDSManagedConnectionPool" objectname="jboss.jca:service=ManagedConnectionPool,name=DefaultDS">  
              <attrib name="AvailableConnectionCount"   alias="DefDS_AvailConns"    type="gauge"/> 
              <attrib name="ConnectionCount"            alias="DefDS_Conns"         type="gauge"/>  
              <attrib name="InUseConnectionCount"       alias="DefDS_InUseConns"    type="gauge"/>  
              <attrib name="ConnectionCreatedCount"     alias="DefDS_CreatedConns"  type="counter"/>  
              <attrib name="ConnectionDestroyedCount"   alias="DefDS_DestroyConns"  type="counter"/>  
          </mbean> 
    </jmx-collection>

五，配置snmp-graph.properties

report.jboss.defaultDS.name=Default DS
report.jboss.defaultDS.columns=DefDS_AvailConns, DefDS_Conns, DefDS_InUseConns, DefDS_CreatedConns, DefDS_DestroyConns
report.jboss.defaultDS.type=interfaceSnmp
report.jboss.defaultDS.command=--title="DS Connection Pool" \
DEF:available={rrd1}:DefDS_AvailConns:AVERAGE \
DEF:minAvailable={rrd1}:DefDS_AvailConns:MIN \
DEF:maxAvailable={rrd1}:DefDS_AvailConns:MAX \
DEF:total={rrd2}:DefDS_Conns:AVERAGE \
DEF:minTotal={rrd2}:DefDS_Conns:MIN \
DEF:maxTotal={rrd2}:DefDS_Conns:MAX \
DEF:inuse={rrd3}:DefDS_InUseConns:AVERAGE \
DEF:minInuse={rrd3}:DefDS_InUseConns:MIN \
DEF:maxInuse={rrd3}:DefDS_InUseConns:MAX \
DEF:created={rrd4}:DefDS_CreatedConns:AVERAGE \
DEF:minCreated={rrd4}:DefDS_CreatedConns:MIN \
DEF:maxCreated={rrd4}:DefDS_CreatedConns:MAX \
DEF:destroyed={rrd5}:DefDS_DestroyConns:AVERAGE \
DEF:minDestroyed={rrd5}:DefDS_DestroyConns:MIN \
DEF:maxDestroyed={rrd5}:DefDS_DestroyConns:MAX \
LINE2:available#0000ff:"Available" \
GPRINT:available:AVERAGE:" Avg \\: %5.2lf %s" \
GPRINT:available:MIN:"Min \\: %5.2lf %s" \
GPRINT:available:MAX:"Max \\: %5.2lf %s\\n" \
LINE2:total#00ff00:"Current " \
GPRINT:total:AVERAGE:" Avg \\: %5.2lf %s" \
GPRINT:total:MIN:"Min \\: %5.2lf %s" \
GPRINT:total:MAX:"Max \\: %5.2lf %s\\n" \
LINE2:inuse#ff0000:"InUse " \
GPRINT:inuse:AVERAGE:" Avg \\: %5.2lf %s" \
GPRINT:inuse:MIN:"Min \\: %5.2lf %s" \
GPRINT:inuse:MAX:"Max \\: %5.2lf %s\\n" \
LINE2:created#00fff0:"Created " \
GPRINT:created:AVERAGE:" Avg \\: %5.2lf %s" \
GPRINT:created:MIN:"Min \\: %5.2lf %s" \
GPRINT:created:MAX:"Max \\: %5.2lf %s\\n" \
LINE2:destroyed#c0a000:"Destroyed" \
GPRINT:destroyed:AVERAGE:" Avg \\: %5.2lf %s" \
GPRINT:destroyed:MIN:"Min \\: %5.2lf %s" \
GPRINT:destroyed:MAX:"Max \\: %5.2lf %s\\n"

配置完毕，重启opennms，大概5分钟后，查看jboss做在的节点，点击resource graphics，就可以看到刚才配置的连接池状态图已经出现了，让opennms持续收集一段时间，线状图就出来了
