Juniper M7i and J6350 - Monitor and report against CPU utilization

I am trying to monitor our Juniper router CPU but the checkbox option does not appear when I go to list resources for the device. I am wondering why I don't get that option, like you do with Cisco routers/switches. I know I could probably use a custom poller, but I would think that something as basic as CPU utilization would be listed under the "List Resources" option. Or am I missing something?


Thanks in advance
