    Description

      Hello,

      after update to Observium 22.2.11868 (stable) Juniper EX4550 switch virtual chassis CPU utilisation increased impossibly and graphs are not usable.

      We even tried to reboot the switch - no luck.

            This is trouble with hardware/firmware on JunOS.

            Since firmware 15.1R5.5 (or around this version) Juniper "fixed" snmp stack for polling ports. And we disabled our hack with separate_walk feature for versions greater.

            In r11872 I increased this version to 15.1R7.9 for 4550. This should fix your issue..
            but I not sure about other versions and hw platforms.

            Hi, sorry for delay.
            You can specify from which version you updated?
