check_snmp_cisco_ports_bandwidth
Project Notes
Expands on the SNMP commands used in "Check SNMP Cisco Traffic" plugin to discover the ports of a Cisco Device and record performance data for them. Usage: check_snmp_cisco_ports_bandwidth -h -s -o -p -i -f -e -w -c or: check_snmp_cisco_ports_bandwidth --help or: check_snmp_cisco_ports_bandwidth --list-interfaces -h -s -f -e or: check_snmp_cisco_ports_bandwidth --clear-temp-files -h -s -h is the hostname or IP address of the Cisco device. -s is the commuity string e.g. 'public'. -w is the warning level in bits/sec, postfix with K,M or G as required. -c is the critical level in bits/sec, postfix with K,M or G as required. -o Can be b for bits/sec, K for Kbits/sec, M for Mbits/sec or G for Gbits/sec. Default b. -p Can be b for bits/sec, K for Kbits/sec, M for Mbits/sec, G for Gbits/sec or - for no performance data. Default -. -i The number of the interface to report. Default is all of them. -f Interface name filter in egrep format. -e Interface name exclude filter in egrep format. Output is the average bitrate in and out from each port taken between now and the previous reading. The first reading will report 'unknown' since at least two timepoints are required for an average. Changes 21 Nov 2012 - 0.1.0 Initial Release 27 Nov 2012 - 0.1.1 Fix incorrect bandwidth calculation and previous time counter 6 Dec 2012 - 0.2.0 Interface list filtering added plus command switches to clear temp files and list interfaces 8 Dec 2012 - 0.3.0 Fixed incorrect previousOutByteCount. Removed requirement to re-run --clear-temp-files every time filters are changed 8 May 2013 - 0.3.1 performance_data() pointed to the wrong arguments in the data file (Thanks to Edgar Matzinger for reporting) 9 Mar 2015 - 0.4.0 Interface number grep updated to handle output from newer versions of snmpwalk. 03 Nov 2016 - 0.5.0 Incorporate bit rate detection bug fix from broerman. Also replace egrep with grep -E since Gnu egrep is now deprecated.

Nice plugin
by dasgeek, February 28, 2013
Nice plugin however can you make an option for the output to be in Mb or MB instead of octets?
