# File: check_traffic.sh
# Description: Nagios check plugins to check network interface traffic in *nix.
# Language: GNU Bourne-Again SHell
# Version: 1.1.6
# Date: 2009-02-20
# Corp.: Chenlei
# Author: chnl@163.com (U can msn me with this.)
# WWW: http://bbs.itnms.net # PerlVersion: U Can find the perl/Net::SNMP Version in the same site.
#########################################################################
# Bugs:
# The Latest Version will be released in http://bbs.itnms.net. # You can send bugs to http://bbs.itnms.net, # or email to me directly: chnl@163.com
#########################################################################
# Todo:
# Do not use unit at performance data, for pnp/rrd graphing better.
# Add the History performance data file support.(maybe)
# Also support the -n args, with interface name to check the traffic.
#########################################################################
# ChangeLog:
#
# Version 1.2.0
# 2010-04-26
# Change default Scale value from 4 to 2, for more friendly output. If you want more excat value, U can change it for youself.
# Fix the Min Interval check bugs, move the check before write the current data to data hist file.
# Add the Max Interval var, default value is 1800, if the hist data file is too old, drop the result.
# Fix the for output "Maybe 32 bit counter overflow, because we got a negative value here." when check too frequent. And set Min_Interval to 30 as default.
# Add the -F option for simple or more simple(s/S) output format.
# Add the -i option for the individual suffix with the CF/STAT_HIST_DATA if necessary.
# Use the 64bit counter as default, when snmp version is v2c. If the system not support it, use 32bit counter instead.
# Get the interface's IF-MIB::ifSpeed, if the traffic value is bigger than it, drop it and output with OOPS and exit with Unkown.
# Modify the CF_HIST_DATA file name from "/var/tmp/check_traffic_${Host}_${Interface}.hist_dat" to
# "/var/tmp/check_traffic_${Host}_${Interface}.hist_dat_${USER}_64|32" for resolving 1)user and 2)64/32bit transfer problem which make 1)the hist data file read/write
# error and 2)with huge error traffic value.
# Add the function for testing Traffic Jitter(The orginal idea come from msn chat wiht wjks@hotmail.com).
# Add a option -p N, N(from 1 to 12) is a number that we comare this time value with the average value of previos N times we had been checked.
# If the value we checked this time is not in our defined scope(a % value) with -w/-c option specified(such as -w 20,20 -c30,30 ),
# we think that it is a traffic jitter.
# For this option, add a file for storing the hist data to stat: /var/tmp/check_traffic_${Host}_${Interface}.hist_dat_${USER}_64|32_ctj_$Num"
#
# Version 1.1.6
# 2009-02-20
# Fix some mistake at perfdata output format with Warning and Critical Value. (thanks for Jiang Shan)
# Remove the redundant code, merge code for --range option.
# Write data before the exit(for the reason of IsFirst), for the next time use.
# When write or read file error, use Unknow instead of Warning severity.
# If get a negative netflow or time interval value here, exit with unknow.
#
# Version 1.1.5
# 2008-09-28
# Fix bug on perfdata output format;
# Fix some spelling mistake;
# Add the Default Value for UseRange as "False";
# Version 1.1.4
# 2008-09-18
# Add -r options, Use Range instead of single value in warning and critical Threshold;
# This option suggestion by zhgypg@hotmail.com at http://www.itnms.net/discuz/thread-1220-1-1.html #
# Version 1.1.3
# 2008-09-17
# Set the default Interval as 12 seconds;
#
# Version 1.1.2
# 2008-08-19
# Check the snmp agent support the 64 bit counter or not;
# Check the interface status, if not OK, exit with Critical status;
# Get the interface name with Interface Index Value;
#
# Version 1.1.1
# 2008-08-06
# Fix some bugs in version compare.
# Use -6 option, use 64 bit counter.
#
# Version 1.1.0
# 2008-06-11
# In snmp v2c, use counters ifHC* instead of if*;
#
# Version 1.0.9
# 2008-04-22
# More friendly output when getting snmp info error.
#
# Version 1.0.8
# 2008-03-31
# Correct some spelling mistake
#
# Version 1.0.7
# 2008-03-28
# If it's the first time to touch hist_dat, echo OK and Tips out;
# Test the hist_dat can be read and write;
# Use the Vars for $OutPut and $PerfData
# Fix some output format.
#
# Version 1.0.6
# 2008-03-25
# Correct Performance data output with Warning and Critical Value of Total and Interval for pnp graphing.
#
# Version 1.0.5
# 2008-03-24
# Correct Performance data output for pnp graphing.
#
# Version 1.0.4
# 2008-03-21
# Correct Performance data output to "Nagios plug-in development guidelines",
# for Graphing the performance data in the web with PNP.
# The standard is: 'label'=value[UOM];[warn];[crit];[min];[max]
#
# Version 1.0.3
# 2008-03-20
# More friendly output with function list_interface().
#
# Version 1.0.2

# File: check_traffic.sh
# Description: Nagios check plugins to check network interface traffic in *nix.
# Language: GNU Bourne-Again SHell
# Version: 1.1.6
# Date: 2009-02-20
# Corp.: Chenlei
# Author: chnl@163.com (U can msn me with this.)
# WWW: http://bbs.itnms.net # PerlVersion: U Can find the perl/Net::SNMP Version in the same site.
#########################################################################
# Bugs:
# The Latest Version will be released in http://bbs.itnms.net. # You can send bugs to http://bbs.itnms.net, # or email to me directly: chnl@163.com
#########################################################################
# Todo:
# Do not use unit at performance data, for pnp/rrd graphing better.
# Add the History performance data file support.(maybe)
# Also support the -n args, with interface name to check the traffic.
#########################################################################
# ChangeLog:
#
# Version 1.2.0
# 2010-04-26
# Change default Scale value from 4 to 2, for more friendly output. If you want more excat value, U can change it for youself.
# Fix the Min Interval check bugs, move the check before write the current data to data hist file.
# Add the Max Interval var, default value is 1800, if the hist data file is too old, drop the result.
# Fix the for output "Maybe 32 bit counter overflow, because we got a negative value here." when check too frequent. And set Min_Interval to 30 as default.
# Add the -F option for simple or more simple(s/S) output format.
# Add the -i option for the individual suffix with the CF/STAT_HIST_DATA if necessary.
# Use the 64bit counter as default, when snmp version is v2c. If the system not support it, use 32bit counter instead.
# Get the interface's IF-MIB::ifSpeed, if the traffic value is bigger than it, drop it and output with OOPS and exit with Unkown.
# Modify the CF_HIST_DATA file name from "/var/tmp/check_traffic_${Host}_${Interface}.hist_dat" to
# "/var/tmp/check_traffic_${Host}_${Interface}.hist_dat_${USER}_64|32" for resolving 1)user and 2)64/32bit transfer problem which make 1)the hist data file read/write
# error and 2)with huge error traffic value.
# Add the function for testing Traffic Jitter(The orginal idea come from msn chat wiht wjks@hotmail.com).
# Add a option -p N, N(from 1 to 12) is a number that we comare this time value with the average value of previos N times we had been checked.
# If the value we checked this time is not in our defined scope(a % value) with -w/-c option specified(such as -w 20,20 -c30,30 ),
# we think that it is a traffic jitter.
# For this option, add a file for storing the hist data to stat: /var/tmp/check_traffic_${Host}_${Interface}.hist_dat_${USER}_64|32_ctj_$Num"
#
# Version 1.1.6
# 2009-02-20
# Fix some mistake at perfdata output format with Warning and Critical Value. (thanks for Jiang Shan)
# Remove the redundant code, merge code for --range option.
# Write data before the exit(for the reason of IsFirst), for the next time use.
# When write or read file error, use Unknow instead of Warning severity.
# If get a negative netflow or time interval value here, exit with unknow.
#
# Version 1.1.5
# 2008-09-28
# Fix bug on perfdata output format;
# Fix some spelling mistake;
# Add the Default Value for UseRange as "False";
# Version 1.1.4
# 2008-09-18
# Add -r options, Use Range instead of single value in warning and critical Threshold;
# This option suggestion by zhgypg@hotmail.com at http://www.itnms.net/discuz/thread-1220-1-1.html #
# Version 1.1.3
# 2008-09-17
# Set the default Interval as 12 seconds;
#
# Version 1.1.2
# 2008-08-19
# Check the snmp agent support the 64 bit counter or not;
# Check the interface status, if not OK, exit with Critical status;
# Get the interface name with Interface Index Value;
#
# Version 1.1.1
# 2008-08-06
# Fix some bugs in version compare.
# Use -6 option, use 64 bit counter.
#
# Version 1.1.0
# 2008-06-11
# In snmp v2c, use counters ifHC* instead of if*;
#
# Version 1.0.9
# 2008-04-22
# More friendly output when getting snmp info error.
#
# Version 1.0.8
# 2008-03-31
# Correct some spelling mistake
#
# Version 1.0.7
# 2008-03-28
# If it's the first time to touch hist_dat, echo OK and Tips out;
# Test the hist_dat can be read and write;
# Use the Vars for $OutPut and $PerfData
# Fix some output format.
#
# Version 1.0.6
# 2008-03-25
# Correct Performance data output with Warning and Critical Value of Total and Interval for pnp graphing.
#
# Version 1.0.5
