Bandwidth Utilization using check_snmp

[Atul Shrivastava]

Actually I can remove this 32 from the query by using the -d option in the check_snmp but the problem is that the value for InOctets is a counter that is increasing. So i have to calculate the difference between two time intervals and then supply it to the nagios. Is there any ready-made option for that.
My requirement is that I want that whenever my bandwidth utilization is more than 90 % , nagios generate an alert. Is it possible and if yes then pls tell me how.
Thanks in advance. 

Regards and have a nice day,

Do an snmpwalk, and you'll see that it's a SNMP COUNTER32 datatype; the plugin is picking up the 32 and returning that.  This has, I was told a few weeks ago, been fixed in CVS, but not yet released, to my knowledge.

Hello All,

I am trying to monitor the Bandwidth Utilization for all the interfaces for rotuers. I am able to get the counters for the InOctets and OutOctets (./check_snmp -H IP -C community -o .1.3.6.1.2.1.2.2.1.10.1 -w 25:1000 -c 15:1000) But when I give the -w and -c option then the interface is showing SNMP OK - 32 continuously and doesn't showing the bandwidth used. Actually I require the diffenence the between the two counter values at some time interval so that i can make a table for this for further use.
Has anyone done some work on that, pls tell me.
Thanks in advance.
