#
# This plugin checks for the QOS status configured on Cisco routers.
#
# 1. QOS summary mode
# -------------------
# In this mode the plugin works as follows:
# - get the entire QoS configuration.
# - sum up all dropped traffic on all interfaces and all classes
# - calculate the average drop rate in bits per second
# - evaluate calculated drop rate against warning/critical thresholds
# - return the corresponding Nagios status & performance data
#
# In order to use this mode you need to call the plugin using the
# following command line arguments:
# -i ALL <- i.e. check for all interfaces
# -m ALL <- i.e. check for all QoS classes
# -w
# -c
#
# Example:
# $ ./check_cisco_qos.pl -H 10.10.10.10 -C public -w 10 -c 20 -i ALL -m ALL
# QOS: Total drop rate (0.00 bits/s) is below warning threshold (10 bits/s): OK
# | Sent=62232.52Bits/s;Dropped=0.00Bits/s
#
# This mode is useful if you just want to know how much is dropped as a result
# of QoS processing.
#
# 2. Class summary mode
# ---------------------
# In this mode the plugin works as follows:
# - get the entire QoS configuration.
# - sum up all dropped traffic on all interfaces for one specific QoS class
# - calculate the average drop rate in bits per second
# - evaluate calculated drop rate against warning/critical thresholds
# - return the corresponding Nagios status & performance data
#
# In order to use this mode you need to call the plugin using the
# following command line arguments:
# -i ALL <- i.e. check for all interfaces
# -m
# -w
# -c
#
# Example:
# $ ./check_cisco_qos.pl -H 10.10.10.10 -C public -w 10 -c 20 -i ALL -m class-default
# QOS: Total drop rate for class class-default (0.00 bits/s) is below warning threshold (10 bits/s): OK
# | Sent=79310.40Bits/s;Dropped=0.00Bits/s
#
# This mode is useful when you have standard QoS policies deployed on multiple
# routers with varying interface names. It allows to define one probe per QoS
# class and to deploy it on multiple routers.
#
# 3. Interface summary mode
# -------------------------
# In this mode the plugin works as follows:
# - get the entire QoS configuration.
# - sum up all dropped traffic of all QoS classes on one specific interface
# - calculate the average drop rate in bits per second
# - evaluate calculated drop rate against warning/critical thresholds
# - return the corresponding Nagios status & performance data
#
# In order to use this mode you need to call the plugin using the
# following command line arguments:
# -i
# -m ALL <- i.e. check for all QoS classes
# -w
# -c
#
# Example:
# # ./check_cisco_qos.pl -H 10.10.10.10 -C public -w 10 -c 20 -i MF1 -m ALL
# QOS: Total drop rate on MF1 (33184.85 bits/s) is above critical threshold (20 bits/s): CRITICAL
# | Sent=2208926.56Bits/s;Dropped=33184.85Bits/s
#
# This mode is useful to monitor dropped traffic per interface.
#
# 4. Detailled mode
# -----------------
# In this mode the plugin works as follows:
# - get the entire QoS configuration.
# - get dropped traffic of one QoS class on one specific interface
# - calculate the average drop rate in bits per second
# - evaluate calculated drop rate against warning/critical thresholds
# - return the corresponding Nagios status & performance data
#
# In order to use this mode you need to call the plugin using the
# following command line arguments:
# -i
# -m
# -w
# -c
#
# Example:
# # ./check_cisco_qos.pl -H 10.10.10.10 -C public -w 10 -c 20 -i MF1 -m class-default
# QOS: Drop rate for class-default on MF1 (1409 bits/s) is above critical threshold (20 bits/s): CRITICAL
# | Sent=73395Bits/s;Dropped=1409Bits/s
#
# 5. Notes
# --------
#
# Interface names:
# ----------------
# This plugin identifies interface names based on their short name like "Gi0/1".
# You can run the plugin in debug mode using "-i ALL -m ALL -d" to find out
# short interface names on your router.
#
#
# Bit rate calculation:
# ---------------------
# The first time you run the plugin it will create a temporary file in /tmp
# This file contains 3 lines:
# - the last drop counter in bits (lastDrop=XXXXXXX)
# - the last sent counter in bits (lastPost=XXXXXXX)
# - the last epoch time in seconds (lastEpoch=XXXXXXX)
#
# The second time you run the plugin, it will compare actual values against
# the previous ones and calculate the rates as follows:
# - dropRate = (current drop counter - last drop counter) / (current epoch - last epoch)
# - sentRate = (current post counter - last post counter) / (current epoch - last epoch)
#
# SNMP counters:
# --------------
# The SNMP counters being used are:
# - cbQosCMDropByte (.1.3.6.1.4.1.9.9.166.1.15.1.1.16)
# --> traffic dropped as a result of QoS processing
# - cbQosCMPostPolicyByte (.1.3.6.1.4.1.9.9.166.1.15.1.1.9)
# --> traffic sent after QoS processing
#
# The Cisco QoS MIB (CISCO-CLASS-BASED-QOS-MIB) also provides some bit rate
# counters but I had some weird results using them; that's why they are not used here.
#
# Changelog:
# ----------
# - 0.1: Initial release
# - 0.2: Fixed bit rate calculation when SNMP counter has wrapped
#
