Dear All, I have a question on SNMP but I think some one on this list can help me out.
I am developing an app something similar to MRTG, I need to monitor a switch and get the number of bits sent and recieved over a period. I use ifInOctets and ifOutOctets of MIB-II to fetch this info from the SNMP server. There are lots of routers and switches which have 32 bit counters and I query them over a period of 5 min to fetch these values. However if these lines are too fast the counters roll over i.e they reach the max value 2^32 and then reset back to 0 and so on. If rollover happens only once within the 5 min duration, I can calculate the bytes sent/recieved but if it occurs more than once during this 5 min period, how does MRTG handle this situation. I know my switch doesn't support 64 bit counters such as ifHCInOctets and ifHCOutOctets. Any hints or leads would be helpful.
