> URL: https://issues.apache.org/jira/browse/AMBARI-5600
> Project: Ambari
> Issue Type: Task
> Components: agent
> Reporter: Nate Cole

> Fix For: 1.6.1
>
>
> 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.
