The script return an Ok, WARNING or CRITICAL if the network flow exeed trigger.
This script use the standard IFMIB and the snmpget/snmpwalk package.
The script is in bash language. I give some comment in the script for helping anyone to modify it.
All comment and help are in french (sorry).

installation :
Put the script in you libexec folder and execute it

help :
./check_debit.sh -H SWITCHHOST -C COMMUNITY -v SNMPPROTO -I INTERFACETOCHECK [-F FORMAT] [-w WARNING] [-c CRITICAL]

-F Format :
percent
debitbps flow in bit/s
debit flow in bit/s, Kb/s, Mb/s, Gb/s

WARNING :
If you choose a format 'debit', you must vrote WARNING and CRITICAL value with the same unit as written in example

EXAMPLES :
check_debit.sh -H 10.10.10.10 -C private -I 4 -F percent -w 60% -c 80%
check_debit.sh -H 10.10.10.10 -C private -I B24 -F debit -w 162M -c 216MB
check_debit.sh -H 10.10.10.10 -C private -I Trk5 -F debitbps -w 921b -c 216b

this latest release permit the "burst" option :
example :
check_debit.sh -H 10.10.10.50 -C private -I 24 -F percent -w 60% -c 80% -b w 3
return a "WARNING" alert if the trafic flow exeed 60% of the bandwith during 3 check (-b w 3) and a "CRITICAL" alert if the bandwith exeed 80%.
OPTION :
-b alert count
alert : 'w' for WARNING burst or 'c' for 'CRITICAL' burst
count : number of script execution during the return value will be "ok" if the network flow exeed the warning value.
