Hi,

I am running PRTG 16.2.25.4709 and have a ZyWall 110 set up with the latest firmware (4.15(AAAA.2)) and am attempting to use SNMP v2c to monitor interface traffic. I have a variety of devices (HP Procurve, Netgear smart managed switches) on the target network, and they provide a decent set of data for traffic monitoring and analysis. The results from the ZyWall seem to be a constant "flatline" indicating zero traffic (although somehow max values exist).

I've used the SNMP tool (I tried to compare the output from the Procurve to the output from the ZyWall - I didn't parse anything significant but I am not an SNMP expert) , and attempted a number of things based on internet research to trigger this interface traffic monitoring. I've removed/re-added, tried using v3, restarted PRTG, looked for updates to PRTG, etc. Any thoughts would be appreciated.

Thanks, Kevin

Hi Kevin,

Did you add the SNMP Traffic Sensor to the device? Please use the SNMP Tester again to perform the "Scan Interfaces" query. Can you please forward the results so that we can check if there is any traffic?

Best regards, Felix

Hi,

Yes the traffic sensor is added. Here is results of SNMP tester / scan interfaces. Than you!

The walk seems to be incomplete. Could you upload it to something like pastebin.com? Maybe it has been cut off.

Hi,

Not sure if my edit, attempting to clean things up, made things messier, but here you go:

No luck unfortunately :( The device simply doesn't expose any valuable OIDs which are necessary in order for the sensor to work properly. You may want to raise a call with ZyXEL about this.
Or something about the device configuration is still off, maybe the permissions are still wrong.

Looks like it has been addressed in the latest firmware. It seems better but not totally accurate still.

[BUG FIX] eITS#160200401, 160200399
SNMP port traffic does not work correctly [Condition] The customer use the network management software named PRTG (based on SNMP) and the port traffic doesn't work correctly. The software will query SNMP to device every 60 seconds; however device will responds there is no traffic but will show the correct value after 5 minutes.
