> In certain environments where SNMP is not working (due to firewall, snmpd not running, etc), "CPU Utilization" alerts show up as "UNKNOWN" with a question mark.
> Can easily replicate this by running "service snmpd stop" on all hosts once the cluster is installed.
> It looks like no other alerts are affected by the lack of functioning SNMP.
> * Drop dependency/install of SNMP
> * Check for java7 or higher and use a JMX metric for this information
> * When java6, do not provide a CPU alert.
