Meet The New Nagios Core Services Platform
Built on over 25 years of monitoring experience, the Nagios Core Services Platform provides insightful monitoring dashboards, time-saving monitoring wizards, and unmatched ease of use. Use it for free indefinitely.
Monitoring Made Magically Better
- Nagios Core on Overdrive
- Powerful Monitoring Dashboards
- Time-Saving Configuration Wizards
- Open Source Powered Monitoring On Steroids
- And So Much More!
Ethernet, Port-channel, Vlan. Also works on standard NIC adaptors.
Checks input/output traffic, unicast pkts, multicast pkts, broadcast pkts, errors and discards on a single interface.
Checks Port-channel member status. Performance data formatting meets Nagios standards.

Remarks:
* Supports all Cisco standard interfaces: TenGigabitEthernet, GigabitEthernet, FastEthernet,
Ethernet, Port-channel, Vlan. Also works on standard NIC adaptors.
* Checks input/output traffic, unicast pkts, multicast pkts, broadcast pkts, errors and discards on a single interface.
* Checks Port-channel member status by comparing port-channel speed to number.
* Performance data formatting meets Nagios standards.
+ Provides stats for bandwidth by percentage and integer values.
+ Packets in/out for unicast, multicast & broadcast.
+ Number of in/out packet discards & errors.
+ Designed specifically for charting with "Splunk for Nagios".
+ Other reporting programs can use perfdata. IE RRD.
* Checks for interface administrative and operational status up/down.
Down on either returns a critical state.
* Allows either textual or the numeric index value of an interface.
* If the interface speed is not specified on the command line it gets it automatically from IfSpeed.
* Bandwidth options allow checks of:
Asymmetrical links such as a DSL line or cable modem where the download and upload speeds are different.
Minimum input bandwidth useful for IPSEC tunnels.
* Can determine interface to query by matching IP address of host with entry in ipAdEntIfIndex (.1.3.6.1.2.1.4.20.1.2).
* Bits per second are the default now. Use -B for bytes.
* RX, TX and absolute values show bytes/octets only.
* SNMP version 2 as we need 64-bit counters. The 32-bit overflows too fast and too frequently.
* Automatic detection of snmp overflows generates a warning state. Max value used -M.
* Perl's given-where "switch" in some places. Look for the correct "use" for your version of perl.
* Supports Perl 5.10
* -h displays help information to see avaliable options.
Suggestions:
Use -b, --bandwidth with -u, --units. This allows for simple input of interface parameters. Usage -u g=gigabits/s,m=megabits/s,k=kilobits/s,b=bits/s.
Example for a 1 Gig interface:
check_iftraffic42.pl -H host1 -C sneaky -i GigabitEthernet1/2 -b 1 -u g
Nagios command:
$USER1$/check_iftraffic42.pl -H $HOSTADDRESS$ -C $USER3$ -i $ARG1$ -b $ARG2$ -u $ARG3$ -w $ARG4$ -c $ARG5$
Example for a 2 Gig Port-channel
check_iftraffic42.pl -H host1 -C sneaky -i Port-channel1 -b 2 -u g –P 2000000000
Nagios command:
$USER1$/check_iftraffic42.pl -H $HOSTADDRESS$ -C $USER3$ -i $ARG1$ -b $ARG2$ -u $ARG3$ -P $ARG4$ -w $ARG5$ -c $ARG6$

i wanted to monitor cisco nexus 5000 but it needs snmpv3 so why not support it?

The script worked well once I created the directory for storing the cache files. The path was different in Ubuntu. Also, it would be really nice to have an option to track packets per second. A patch (check_iftraffic5-pps.pl.patch.txt) was available at one point but is now offline.
I've added ability to monitor not only bandwidth, but also PPS (unicast packets per second). Here is the patch:

I had to change to the old 32-bit counters for my windows server, took me about 30 min to figure out.
I added an extra switch (x) to set it to 32 when needed.
Patch Below:
--------------
nagios@deimos ~/test $ diff check_iftraffic42.pl check_iftraffic42.pl.original
123,126c123,128
#Older 32-bit counter:
> #my $snmpIfOutOctets = '1.3.6.1.2.1.2.2.1.16';
> my $snmpIfOutOctets = '1.3.6.1.2.1.31.1.1.1.10';

tOctets32;

Since the switch to 64 bit counters i am getting totally weird average values like:
CRITICAL - Average IN: 3.41Tbps (170252.50%), Average OUT: 970.95Gbps (48547.45%) Total RX: 5.81TBytes, Total TX: 1.66TBytes|inUsage=170252.50%;85;98 outUsage=48547.45%;85;98 inBandwidth=3405050072654.40bps outBandwidth=970948946016.00bps inAbsolut=6384549288059 outAbsolut=1820440453052 Bandwidth=2000000000
The old version with 32 bit counters works fine, but of course it loops all the time on my fast interfaces.
Any idea ?
PS: Checked system is a Cisco Catalyst 4510 and several 2960

At line 547 please change %.01d to %s. This should take care of it.
if ( open(FILE,">".$TRAFFIC_FILE."_if".$iface_number."_".$host_address )) {
printf FILE ("%s:%s:%s
", $update_time, $in_bits, $out_bits );
close(FILE);
};
