[rrd-users] graph from mysql

[Shabbir Ahmed]

quering the device snmpbulkget -c public 119.156.203.217
.1.3.6.1.2.1.2.2.1.10 -v 2c
returns 32bit integers
IF-MIB::ifInOctets.20971520 = Counter32: 0
IF-MIB::ifInOctets.20972032 = Counter32: 0
IF-MIB::ifInOctets.20972544 = Counter32: 1295822366
IF-MIB::ifInOctets.20973056 = Counter32: 1295822366
IF-MIB::ifInOctets.20973568 = Counter32: 1295822366
IF-MIB::ifInOctets.20974080 = Counter32: 1295822366


2nd question is most of the values are always same is it the reason port is
down?

3rd question what if counter reaches its up limit and starts from 0 again,
how rrd tool manages it? or should we have to manage our self?

kindly help further with this issue.

thanks,
