I try to monitor the bandwidth of the WAN-interface on a SonicWall TZ 190 Enhanced. From an auto discovery I select the WAN interface. The problem is that the "Traffic in(ID 0)" graph is always 0.

Any ideas?

Lind regards, Andreas

P.S. using PRTG Network Monitor 12.2.2.2149 (588 sensors configured) Enterprise Console V12.2.2.2149 Server: W2K8R2 x64

Hello,

please use our SNMP Tester to scan against the Sonicwall, with the Option "Scan Available Standard Interfaces". Please do this test twice with about one minute in between and then compare the counter numbers for this interface. Do they change?

best regards

Hi, yes they change! But not in PRTG.

The first run:
Found standard interfaces:
1: (001) WAN (WAN),Connected,10 MBit/s,Ethernet,
2: (002) LOOPBACK,Connected,0 KBit/s,Software Loopback,
3: (003) LAN (LAN),Connected,100 MBit/s,Ethernet,
4: (004) OPT (Unassigned),Not Connected,0 KBit/s,Ethernet,
5: (005) WWAN (WAN),Not Connected,0 KBit/s,Ethernet,

Testing standard interfaces...
Test 1 (1.3.6.1.2.1.2.2.1.10.1,1.3.6.1.2.1.2.2.1.16.1): in=3241127849  out=2025612162
Test 2 (1.3.6.1.2.1.2.2.1.10.2,1.3.6.1.2.1.2.2.1.16.2): in=0  out=
Test 3 (1.3.6.1.2.1.2.2.1.10.3,1.3.6.1.2.1.2.2.1.16.3): in=1940774287  out=1183078548
Test 4 (1.3.6.1.2.1.2.2.1.10.4,1.3.6.1.2.1.2.2.1.16.4): in=0  out=
Test 5 (1.3.6.1.2.1.2.2.1.10.5,1.3.6.1.2.1.2.2.1.16.5): in=  out=


and the second run:
Found standard interfaces:
1: (001) WAN (WAN),Connected,10 MBit/s,Ethernet,
2: (002) LOOPBACK,Connected,0 KBit/s,Software Loopback,
3: (003) LAN (LAN),Connected,100 MBit/s,Ethernet,
4: (004) OPT (Unassigned),Not Connected,0 KBit/s,Ethernet,
5: (005) WWAN (WAN),Not Connected,0 KBit/s,Ethernet,

Testing standard interfaces...
Test 1 (1.3.6.1.2.1.2.2.1.10.1,1.3.6.1.2.1.2.2.1.16.1): in=3246416195  out=2027160057
Test 2 (1.3.6.1.2.1.2.2.1.10.2,1.3.6.1.2.1.2.2.1.16.2): in=0  out=
Test 3 (1.3.6.1.2.1.2.2.1.10.3,1.3.6.1.2.1.2.2.1.16.3): in=1942035905  out=1188059356
Test 4 (1.3.6.1.2.1.2.2.1.10.4,1.3.6.1.2.1.2.2.1.16.4): in=0  out=
Test 5 (1.3.6.1.2.1.2.2.1.10.5,1.3.6.1.2.1.2.2.1.16.5): in=  out=

This looks ok, but in PRTG Enterprise Console or the WebInterface "out=" is always 0. (Sorry I changed IN and OUT by mistake in my first post).

Kind regards, Andreas

How much time did pass by between the two scans? For a minute the changes seem very small, can you please make sure that it's not simply the wrong unit in PRTG? Not that it's a rounding issue with the decimal places.

Hi, about 3 minutes between the scans.

But playing around with SNMP tester and GetIf points me to the right direction. And finally I got it working. The sensor inherited some snmp settings. Especially the "SNMP version v2c", and 64-bit counter , which seems not supported by the Sonicwall(Firmware too old?). I broke the inheritance and set these settings to SNMP v1 and force 32-bit counter...

Nothing happens, same problem as before. So I decided to add the same sensor again, and tadaa, the newly added sensor shows 'in' AND 'out' Traffic. :)

Thanks. Kind regards, Andreas
