Hi again!
If that's all you need, you do a walk with PHP (or faster alternative)
and push the data into a database with a timestamp. From there you can
monitor the links as often as you like, just as long as you remember
that the data you read is as old as the pollings feeding the dB with data.
$ifInOctArray=snmp2_real_walk($RouterIP, $community,
"IF-MIB::ifHCInOctets") or die("$argv[0]: unable to walk OID
IF-MIB::ifHCInOctets");
$ifOutOctArray=snmp2_real_walk($RouterIP, $community,
"IF-MIB::ifHCOutOctets") or die("$argv[0]: unable to walk OID
IF-MIB::ifHCOutOctets");
Stuff it into your dB of choise and start reading the data! Use
ifHCOutOctets instead of ifOutOctets since the 32-bit counters in the
latter will top out at ~500 Mbps if polling every minute.
Use this to graph the data directly from the dB (if you need to create
graphs, if not, just read the data from the dB):
