print <<EOT;
-v, --verbose
print extra debugging information (including interface list on the system)
-h, --help
print this help message
-H, --hostname=HOST
name or IP address of host to check
-C, --community=COMMUNITY NAME
community name for the host's SNMP agent (implies v1 protocol)
-l, --login=LOGIN ; -x, --passwd=PASSWD, -2, --v2c
Login and auth password for snmpv3 authentication
If no priv password exists, implies AuthNoPriv
-2 : use snmp v2c
-X, --privpass=PASSWD
Priv password for snmpv3 (AuthPriv protocol)
-L, --protocols=<authproto>,<privproto>
<authproto> : Authentication protocol (md5|sha : default md5)
<privproto> : Priv protocole (des|aes : default des)
-P, --port=PORT
SNMP port (Default 161)
-n, --name=NAME
Name in description OID (eth0, ppp0 ...).
This is treated as a regexp : -n eth will match eth0,eth1,...
Test it before, because there are known bugs (ex : trailling /)
-r, --noregexp
Do not use regexp to match NAME in description OID
-i, --inverse
Make critical when up
-a, --admin
Use administrative status instead of operational
-D, --dormant
Dormant state is an OK state
-o, --octetlength=INTEGER
max-size of the SNMP message, usefull in case of Too Long responses.
Be carefull with network filters. Range 484 - 65535, default are
usually 1472,1452,1460 or 1440.
-f, --perfparse
Perfparse compatible output (no output when interface is down).
-e, --error
Add error & discard to Perfparse output
-S, --intspeed
Include speed in performance output in bits/s
-y, --perfprct ; -Y, --perfspeed
-y : output performance data in % of max speed
-Y : output performance data in bits/s or Bytes/s (depending on -B)
-k, --perfcheck ; -q, --extperfcheck
-k check the input/ouput bandwidth of the interface
-q also check the error and discard input/output
--label
Add label before speed in output : in=, out=, errors-out=, etc...
-g, --64bits
Use 64 bits counters instead of the standard counters when checking
bandwidth & performance data for interface >= 1Gbps.
You must use snmp v2c or v3 to get 64 bits counters.
-d, --delta=seconds
make an average of <delta> seconds (default 300=5min)
-B, --kbits
Make the warning and critical levels in K|M|G Bits/s instead of K|M|G Bytes/s
-G, --giga ; -M, --mega ; -u, --prct
-G : Make the warning and critical levels in Gbps (with -B) or GBps
-M : Make the warning and critical levels in Mbps (with -B) or MBps
-u : Make the warning and critical levels in % of reported interface speed.
-w, --warning=input,output[,error in,error out,discard in,discard out]
warning level for input / output bandwidth (0 for no warning)
unit depends on B,M,G,u options
warning for error & discard input / output in error/min (need -q)
-c, --critical=input,output[,error in,error out,discard in,discard out]
critical level for input / output bandwidth (0 for no critical)
unit depends on B,M,G,u options
critical for error & discard input / output in error/min (need -q)
-s, --short=int
Make the output shorter : only the first <n> chars of the interface(s)
If the number is negative, then get the <n> LAST caracters.
-t, --timeout=INTEGER
timeout for SNMP in seconds (Default: 5)
-V, --version
prints version number
Note : when multiple interface are selected with regexp,
all be must be up (or down with -i) to get an OK result.

This plugin intends to report the OS version string of a supported vendor.
Currently it is parsing Cisco IOS, PIX and ASA versions through SNMP sysDescr polls.
In 'discovery mode' without using the option '-f', this plugin returns the OS
version string with 'OK' if the version could be fetched, or 'UNKNOWN' if not.
Useful if you need a view on what is out there in a enterprise environment.
In 'compliance mode' by specifying '-f', this plugin compares the device OS
version string against a list of categorized (approved) OS versions. It is
meant to identify devices running a rogue, obsolete or vulnerable OS version.
Usually this check runs only once in a couple of hours or even longer periods.
The configuration file format is in the check_snmp_patchlevel.cfg template.

# ============================== SUMMARY =====================================
#
# Program : check_snmp_temperature.pl
# Version : 0.33
# Date : Aug 08 2008
# Author : William Leibzon - william@leibzon.org
# Summary : This is a nagios plugin that checks temperature sensors
# using SNMP. Dell, HP, Cisco and other types are supported
# and for other systems OIDs can be easily specified too

#
# ===================== INFORMATION ABOUT THIS PLUGIN =========================
#
# This Temperature check plugin that retreives temperature sensor values from
# SNMP and can issue alerts if selected parameters are above given number
# It also returns performance data for further nagios 2.0 post-processing
#
# This program is written and maintained by:
# William Leibzon - william(at)leibzon.org
# It is partially based on check_snmp_* plugins by:
# Patrick Proy (patrick at proy.org)
#
# ============================= SETUP NOTES ====================================
#
# Make sure to check and if necessary adjust the the path to utils.pm
# Make sure you have Net::SNMP perl module installed
#
# If you want to check Dell servers, HP server, Juniper routers or
# Cisco Switches/Routers (cisco 7500, 5500, 2948) then you may skip
# much of the configuration hassles and use pre-programmed settings
# by using "--type" (or -T) parameter, you do still need to specify
# though if you want output as C or F with '-o' option (see examples).
# The plugin currently does not support finding critical & warning
# thresholds which most systems also report in SNMP, so actual thresholds
# you will need to specify as well.
#
# NOTE: If you've previously used 0.2x version of this plugin to
# check HP equipment, beware that 0.3 version has "incompatible"
# change in that it returns human-readable sensor names rather
# then using HP locale ids to enumerate sensors. If you need
# old behavior then instead of using '-T hp' as parameter
# use '-N 1.3.6.1.4.1.232.6.2.6.8.1.3 -D 1.3.6.1.4.1.232.6.2.6.8.1.4'
#
# If you're using some other device then you need to check documentation to
# figure out correct parameters for this plugin, then specify base temperature
# sensor names table OID with '-N' and values table OID with '-D. You also need
# to specify what base sensor temperature data type is with "-i" (see below).
#
# The way plugin works is to walk the snmp tree from base names OID and find
# all the sensor names. Then it compares names given with '-a' (names are
# seperated by ',') to those found in the snmp tree (in '-a' you're expected
# to specify one word which would be found in the full sensor name and
# is unique for thaqt `sensor) and uses OID ending (i.e. part of OID after
# the base) and adds it to base value table OID to create OID to be retrieved
# (similar to how you find ethernet statistics OIDs based on name of the
# interface and in fact many of SNMP parameters are like that).
#
# Note: If you don't know temperature sensor names on your system do:
# check_snmp_temperature -v -A '*' ...
# (using '-v' option forces debugging output that should further help)
#
# If your system does not have table with sensor names you can still use
# this plugin if you know exact temperature data OIDs. Then you specify list
# of names sensors should be known by with '-n' option and list of data OIDs
# with '-d' option (this can also be useful if you want to avoid having plugin
# do snmp table walk each time as retrieving specific list of OIDs is faster).
# You will still need to specify what is likely the same sensor names you
# you put in '-n' with '-a' or '-A' option.
#
# Request: If you have an new type of device and as per above you figured
# out SNMP parameters that work, please send me email with this
# information so that I can add it as a new system type.
#
# The values retrieved are compared to specified warning and critical values,
# but first the temperature has to be converted from base measurement units to
# measurement units you want. These units are Celsius (C) or Fahrenheit (F)
# or Kelvin (K) with input measurement unit specified with '-i' and output
# specified with '-o'. For input you sometimes have situation where sensor
# reports 10xRealValue, i.e. 33.5C is reported as 335 - this is supported
# too and then input type is specified as '-i 10C'.
#
# Warning and critical values are specified with '-w' and '-c' and each
# one must have exact same number of values (separated by ',') as number
# of sensor names specified with '-a'. Any values you dont want to compare
# you specify as 0 or just not specify (i.e. -w ',50,'). In some cases you
# might not get data for specific sensor and want to substitute default
# value - this is supported with '-u' option (note that default values
# is in fact compared against -w and -c).
#
# Additionally if you want performance output then use '-f' option to get all
# the sensors specified in '-a' or specify particular list of sensors for
# performance data with '-A' (this list can include names not found in '-a').
# A special option of -A '*' will allow to get data from all sensors found
# and is this very useful to find what sensors you have with manual run.

#
# ==================== CHANGES/RELEASE, TODO ==================================
#
# 0.33 - Aug 2008 : Full SNMPv3 support (contrib patch by Nicolas Deffayet)
# 0.33 - May 2008 : Minor bug fixes. Added baytech pdu SNMP OIDs
# 0.31 - Feb 2008 : Bug fix due to report by Michael Timmers. The issue
# was with sensor list that contains a name which matches
# by regex with some other later sensor name. In this
# case it was Juniper with "Routing Engine" which was
# followed by "Routing Engine PCMCIA Card 0" sensor.
# 0.3 - Jan 2008 : Added '-n' and '-d' options to specify exact list of
# sensor names and oids.
# Also when you specify 'hp' type, the plugin will now
# provide human-readable sensor names rather then purely
# an id of their sensor locale (this is basicly special
# hack just for HP since I don't know anyone else who
# hard-coded sensor names by ids into SNMP MIB).
# 0.23 - Dec 2007 : Bug Fixes (especially one involving F as input format)
#
# TODO and older revision history:
#
# 1. [DONE - Aug 2006] To support multiple types of equipment add config
# array/hash and --type parameter
# 2. More plugin types for various other equipment need to be added ...
# [DONE - Dec 2006] - added Juniper & HP
# 3. Need to update warn & crit parameters parsing code so it would support
# both low and high values with '<' and '>' prefixed and using '~' for
# don't check rather then 0
# [DONE - Dec 2006] - added quick hack to interpret empty values
# (i.e. -w ",90,") as dont check instead of specifying '0' directly
# Note: Low temperature value checks are rarely needed for network
# equipment so this is not high priority right now and will
# be done together with #4 most likely as part of some general
# library that would be shared with check_snmp_table and quite
# likely other plugins where multiple "attributes" are specified
# 4. Support specifying table OIDs for temperature threashold values.
# I'll do it only after adding optional file caching so these values
# can be retrieved about once every day rather then for each check.
#
# Note: if you want #3 or #4 done faster for specific application,
# contact me privately to discuss

-N, --oidtable_attribnames=OID_STRING
Base table OID to walk through to find names of those attributes supported and from that corresponding data OIDs
-D, --oidtable_attribdata=OID_STRING
Base table OID for sensor attribute data, one number is added to that to make up full attribute OID
-n, --sensor_names=STRING[,STRING[..]]
List of sensor names when -N is not used and sensors are specified with exeact oids

List of exact data OIDs for sensors specified with -n (specify this when -N and -D are not used)
-a, --attributes=STRING[,STRING[..]]
Which attribute(s) to check. This is used as regex to check if attribute is found in sensor names.
As an example for Dell the attribute names to use are: PROC_1, PROC_2, Ambient, Planar, Riser
-A, --perf_attributes=STRING[,STRING[..]]
Which attribute(s) to add to as part of performance data output. These names can be different then the
ones listed in '-a' to only output attributes in perf data but not check. Special value of '*' gets them all.
-f, --perfparse
Used only with '-a'. Causes to output data not only in main status line but also as perfparse output
-o --out_temp_unit=C|F|K
What temperature measurement units are used for output and warning/critical - 'C', 'F' or 'K' - default is 'C'
-i --in_temp_unit=[num]C|F|K
What temperature measurement reported by data OID - format is <num>C|F|K (default is 'C')
where num is used if data is num*realdata, i.e. if reported data of 330 means 33C, then it is: -i 10C
-u, --unknown_default=INT
If attribute is not found then report the output as this number (i.e. -u 0)
-T, --type=dell|hp|cisco1|juniper|alteon
This allows to use pre-defined system type to set Base, Data OIDs and incoming temperature measurement type
Currently support systems types are: dell, hp, cisco1 (7500, 5500, 2948, etc), juniper, alteon
