in USG FLEX H Series

There is a support article titled "What OIDs do the Zyxel firewalls (USG/ATP/VPN) use to monitor key parameters?". It has OIDs for System CPU current Usage & System current session number. When I query those and compare them to the values on the 200H System Dashboard, they are significantly different.

I also get erratic responses from the 200H when querying SNMP. Sometimes it returns results immediately. Sometimes my snmp client times out with its defaults of 1 second timeouts and 5 retries. If I turn up the timeout to 10 seconds and set retries to 3, then it seems to complete all queries but is still erratic.

    Hi @SAI_Mike,

    CPU
    Web GUI: The value doesn't contain fast path traffic.
    SMNP "sysCPUUsage": The value contains both fast-path traffic and other traffic (ex. calculate the statistics, GUI data processing...).
    Note: You can use OID (.1.3.6.1.4.1.890.1.15.3.2.21) to monitor CPU usage for fast-path traffic.

    Session
    Web GUI: The value contains forward sessions only
    SMNP "sysSessionNum": The value contains not only forward sessions but all sessions
