Hello. In company we need automation monitoring for stream nodes like queue processor or job sheduler, for send email if every nodes is shutdown.
But if every stream nodes is shutdown, this cant work.
Any ideas how i an resolve this problem by only using Pega (8.6.2)?
I guess this is not feasible 
You can only fully monitor by an external tool. PDC can also help you.
Yet, I also achieved the same by monitoring pr_sys_statusnodes.
From there you can easily check your number of nodes for your system name and by checking pylastpulsedatetime you can also find out whether a node is technically up but not working.

PDC have option to generate email and SMS notification.
Check for different component what event triggered in PDC, configure notification for those required events.
