[Email protected] Libexec]#/usr/local/nagios/libexec/check_traffic.sh-h

Usage:

./check_traffic.sh [-v] [-6] [-r]-v 1|2c|3-c snmp-community-h host [-l]-i interface-w in, Out-warning-value -C in, out-critical-value-k/m-b/b

Example:

./check_traffic.sh-v 2c-c public-h 127.0.0.1-i 4-w 200,100-c 300,200-k-B

we can use-r to use Range Value Options:

Span style= "FONT-FAMILY:CALIBRI;" >example:

if you don t use-k/m-b/b options , default-k-B, corresponding to Kbps

Make sure, the check interval greater than 5 Seconds.

Or Modify the Min_interval var in this file line 180.

And, if you want in Verbose mode, use-v, to check the debug messages in the file/tmp/check_traffic.$$.

Or use./check_traffic.sh [-v]-V 1|2c|3-c snmp-community-h host-l

To list all interfaces on specify host.

vi/usr/local/nagios/etc/object/command.cfg Add the following content:

Define Command{

Command_name Check_bandwidth

Command_line $USER 1$/check_traffic.sh-v 2c-c snmp-community-h $HOSTADDRESS $-I $ARG 1$-w $ARG 2$, $ARG 3$-C $ARG 4$, $AR g5$

}

Note: the-C parameter is the community value set on the server;

-I is uppercase I, which is the index value of the NIC interface

The two parameters of- w and- c are in/out traffic thresholds, respectively

3.3Editwindows.cfgHost configuration file

First, use the following command to view the network card information for the monitored Windows Host:

/usr/local/nagios/libexec/check_traffic.sh-v 2c-c snmp-community-h ipadd-l

Then it will list the network card information of the monitored machine, check the network card that needs to be monitored, and record its index value.

As shown in the previous example, the command is:

/usr/local/nagios/libexec/check_traffic.sh-v 2c-c public1-h 192.168.19.142–l as shown: (Picture in attachment document)

VI windows.cfg Add the following:

Define Service{

HOST_NAME Winserver

Service_description Traffic

Check_command check_bandwidth!10!200000!300000!400000!500000
