my $version = "0.2";

my $release = "2010/03/05";
|
||||
#
|
||||
# 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 <warning drop rate in bits per second>
|
||||
# -c <critical drop rate in bits per second>
|
||||
#
|
||||
# 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 <QoS class name>
|
||||
# -w <warning drop rate in bits per second>
|
||||
# -c <critical drop rate in bits per second>
|
||||
#
|
||||
# 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 <interface name>
|
||||
# -m ALL <- i.e. check for all QoS classes
|
||||
# -w <warning drop rate in bits per second>
|
||||
# -c <critical drop rate in bits per second>
|
||||
#
|
||||
# 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 <interface name>
|
||||
# -m <QoS class name>
|
||||
# -w <warning drop rate in bits per second>
|
||||
# -c <critical drop rate in bits per second>
|
||||
#
|
||||
# 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
