Check_iftraffic64 is an updated version of (check_iftraffic3) and has been changed to use 64 bit SNMP counters but can still handle 32 bit. Some math issues found in check_iftraffic3 were resolved as well.

Version .6:
I've removed text from the output that was not necessary. Thanks Nicholas Coulin for pointing it out.


Version .5:
Significant features in this check include the following:

1. Capable of handling 32 and 64 (default) bit SNMP counters
2. Auto detects max bandwidth (unless specified)
3. Supports asymetric links, i.e. Ability to specify different BW limits (in and out) other than what is automatically detected. Good for Internet connections that have different up and down speeds
4. NagVis weathermap line compatible perfdata output
5. Returns CRITICAL status when the interface is down.


examples:

# Simple 64 bit check of interface used as the primary host interface (based on IP address of host1)
check_iftraffic64.pl -H host1 -C sneaky

# 32 bit mode check of interface index 5 in bits/s with 100m bandwidth limit
check_iftraffic64.pl -H host1 -C sneaky -i 5 -B -b 100 -u m --32bit

# Check of interface using address 192.168.1.1 in bits/s running 50m down (in) and 10m up (out)
check_iftraffic64.pl -H host1 -C sneaky -A 192.168.1.1 -B -I 50 -O 10 -u m
