# Mel - 2016-09-15 - icinga2 check apc ups
# Mel - 2016-09-19 - add cyber power ups checks - Note: CyberPower has some
#                    "Wrong Type" errors in their MIB file. These are made
#                    functional by using OID numerics and not OID strings,
#                    and also not referencing their their MIB file. So I have
#                    removed the OID strings for APC and removed the -mALL
#                    variable for consistency.
# Mel - 2016-09-20 - fix cyberpower reports voltage in tenths of volts
# Mel - 2016-09-29 - add bash version check, change sysName to numeric MIB
#                    for consistency
# Mel - 2017-04-11 - added option to skip battery replace flag check, since
#                    cyber power 202 and 303 cards (and maybe others) do not 
#                    have this OID. Recommend 205/305 cards instead. However,
#                    this OID is really just a calculation of last battery 
#                    replace date + 3 years, and battery replace date can
#                    be manually reset through the web interface.
# Mel - 2017-04-13 - change upstype to autodetect.
# Mel - 2017-04-18 - removed model detect attempt using sysObjectID
#                    Note: For sysDescr CyberPower always returns "UPS SNMP Card"
#                    across all cards tested. APC returns full details, example:
#                    APC Web/SNMP Management Card (MB:v4.0.1 PF:v6.1.1 PN:apc_hw05_aos_611.bin AF1:v6.1.1 AN1:apc_hw05_sumx_611.bin MN:AP9630 HR:05 SN: ZA1425004783 MD:06/18/2014) (Embedded PowerNet SNMP Agent SW v2.2 compatible)
# Mel - 2017-04-28 - Fix calibration/diagnostic days result in perfdata when 
#                    they have not been run
# Mel - 2017-05-10 - Typo: unsuppoted

usage(){
    cat << MEL
Usage:
  $(basename $0) [OPTION]... [OPTION]...

Options:
  -b, --onbattcrit Set CRITICAL any time ups is on battery. Without this
     "on battery" is only warning. In that case final status would only
     be warning until run time falls below critical level (set by -R)
  -B, --noreplaceck, Do not check battery replace status. The battery
     replace status is just a calculation the battery replaced date plus
     3 years. The battery replace date can be set in the web interface.
     The cyber 202 and 303 cards (and maybe others) do not have this OID. 
  -C STRING, --community STRING, The SNMP community string. Defaults to
     "public".
  -d CHAR, --degrees CHAR, Accepted values are C, c, F, or f. For celsius or 
     fahrenheit. Invalid values or not set will default to fahrenheit. This
     setting is also used by -t and -T to determine default values.
  -h, --help  Show this help message.
  -H HOSTNAME, --host HOST, Set HOSTNAME or IP to check.
  -i INTEGER, --inlow INTEGER, Set WARNING status if input voltage is less
     than INTEGER. Values are not checked for sanity, except inlow must be
     less than inhigh. Defaults to 106.
  -I INTEGER, --inhigh INTEGER, Set WARNING status if input voltage is
     greater than INTEGER. Values are not checked for sanity, except inlow
     must be less than inhigh. Defaults to 133. (Note: inlow and inhigh
     can result in CRITICAL status if -v flag is set)
  -l INTEGER, --warnload INTEGER, Set WARNING status if ups load is greater
     than INTEGER. loadwarn values should be less than loadcrit values.
     Defaults to 70.
  -L INTEGER, --critload INTEGER, Set CRITICAL status if ups load is greater
     than INTEGER. loadcrit values less than loadwarn values will be set to
     loadwarn +1. Defaults to 80.
  -r INTEGER, --warnrun INTEGER, Set WARNING status if runtime is less than
     INTEGER minutes. If not set, defaults to 10. Minimum value is 2.
  -R INTEGER, --critrun INTEGER, Set CRITICAL status if runtime is less than
     INTEGER minutes. If not set, defaults to 8. critrun values greater than
     warnrun values will be set to warnrun -1. Minimum value is 1.
  -t INTEGER, --warntemp INTEGER, Set WARNING status if battery temperature
     is more than INTEGER degrees. Celsius or fahrenheit is set by -d.
     If not set, defaults to 45 celsius, or 113 fahrenheit (see -d)
  -T INTEGER, --crittemp INTEGER, Set CRITICAL status if battery temperature
     is more than INTEGER degrees Celsius or fahrenheit is set by -d. 
     Crit values not greater than warn values will be set to warn value +1.
     If not set, defaults to 50 celsius, or 122 fahrenheit. (see -d)
  -v, --voltcrit Set CRITICAL for input voltage low or high results. (-i
     and -I)
  -V --version Show version information.
  -w INTEGER, --diagwarn INTEGER, Set WARNING status if number of days since
     last diagnostic is more than INTEGER days. Default is 15. This test may
     be disabled with -x.
  -W INTEGER, --diagcrit INTEGER, Set CRITICAL status if number of days since
     last diagnostic is more than INTEGER days. Default is 20. This test may
     be disabled with -x.
  -x, --nodiagck Disables test for number of days since last diagnostic.
     Implies -z.
  -X, --nocalibck Disables test for number of days since last calibration.
  -y INTEGER, --calibwarn INTEGER, Set WARNING status if number of days since
     last calibration is more than INTEGER days. This test may be disabled
     with -X. Default is 365.
  -Y INTEGER, --calibcrit INTEGER, Set CRITICAL status if number of days since
     last calibration is more than INTEGER days. This test may be disabled
     with -X. Default is 400.
  -z, --nodiagdata Disables diagnostic days performance data.
  -Z, --nocalibdata Disables calibration days performance data.
Example:
  $(basename $0) -H 10.1.2.3 -C public -b -d c -i 105 -I 133 -l 20 -L 40 -r 15 -R 10 -t 44 -T 51 -w 14 -W 21 -X
