Reports 11.1.2 g

Hi,

I have a question about how verify reports server. I have used  http://IP:9002/reports/rwservlet/getserverinfo , and the output was the following:

<serverInfo name="" version="11.1.2.2.0">

<host>srv-vln.com</host>

<processId>5711</processId>

<startTime>1433349306765</startTime>

<queue maxQueueSize="1000"/>

<engine id="rwEng" activeEngine="2" runningEngine="0" totalBusyEngines="0" totalIdleEngines="2">

<engineInstance name="rwEng-0" processId="19069" status="1" runJobId="-1" curJobExecTime="-1" idleTime="22985" numJobsRun="0" lifeLeft="50" nls="SPANISH_SPAIN.WE8MSWIN1252" totalRunTime="0" totalIdleTime="383"/>

<engineInstance name="rwEng-1" processId="18361" status="1" runJobId="-1" curJobExecTime="-1" idleTime="23380" numJobsRun="1" lifeLeft="49" nls="SPANISH_SPAIN.WE8MSWIN1252" totalRunTime="1" totalIdleTime="389"/>

</engine>

<engine id="rwURLEng" activeEngine="0" runningEngine="0" totalBusyEngines="0" totalIdleEngines="2"/>

<performance>

......

......

I would like know the differents engine states, because only we could simulated "ready(1)" and "running(3)" states. There been any more? It's the correct way to check this states?
