We include a few others, but it looks like we are missing the sxe-.* pattern which is present on some of our higher end gear.

Hey guys!
Just wanted to share a little tip on how to increase Observium polling performance on juniper boxes.
This might be old news for some but I just found it.
You can create a filter on junos-device that filters out certain interfaces from SNMP view.
https://www.juniper.net/documentation/en_US/junos/topics/task/configuration/ snmp-filter-interfaces-configuring-junos-nm.html
I can recommend using:
set snmp filter-interfaces all-internal-interfaces
set snmp filter-interfaces interfaces "^sxe-.*"
This will filter out all useless internal interfaces from polling and discovery by Observium.
Especially when you have large juniper switch stacks the total number of internal interfaces are a lot which slows down polling.
Filtering them out actually makes a big difference.
If you got a lot of juniper gear, try it out and please share the speedup in pollingtime!
