[Observium] Alerts based on Juniper FW counters

Hello,

Using Observium Professional, svn up’d today. For Juniper MX, the Firewall tab graphs firewall filters, policers, etc., however I can’t seem to find a way to create alerts based on any of those values. Am I missing it somewhere or is that not supported?

Specifically I’m looking to be alerted when there is a policer violation.

Thanks in advance.
