sub get_help{
return <<EOT;
[-H <hostname>]
hostname or IP of the IPMI interface.
For \"-H localhost\" or if no host is specified (local computer) the
Nagios/Icinga user must be allowed to run
ipmimonitoring/ipmi-sensors/ipmi-sel/[ipmi-fru] with root privileges
or via sudo (ipmimonitoring/ipmi-sensors/ipmi-sel/[ipmi-fru] must be
able to access the IPMI devices via the IPMI system interface).
[-f <FreeIPMI config file>]
path to the FreeIPMI configuration file.
Only neccessary for communication via network.
Not neccessary for access via IPMI system interface (\"-H localhost\").
It should contain IPMI username, IPMI password, and IPMI privilege-level,
for example:
username monitoring
password yourpassword
privilege-level user
As alternative you can use -U/-P/-L instead (see below).
[-U <username> -P <password> -L <privilege level>]
IPMI username, IPMI password and IPMI privilege level, provided as
parameters and not by a FreeIPMI configuration file. Useful for RHEL/
Centos 5.* with FreeIPMI 0.5.1 (this elder FreeIPMI version does not
support config files).
Warning: with this method the password is visible in the process list.
So whenever possible use a FreeIPMI confiugration file instead.
[-O <FreeIPMI options>]
additional options for FreeIPMI. Useful for RHEL/CentOS 5.* with
FreeIPMI 0.5.1 (this elder FreeIPMI version does not support config
files).
[--seloptions <FreeIPMI SEL options>]
additional options for FreeIPMI SEL command. Useful for passing extra
options to the ipmi-sel call, e.g. --assume-system-event-records:
--seloptions '--assume-system-event-records'
[-b]
backward compatibility mode for FreeIPMI 0.5.* (this omits the FreeIPMI
caching options --quiet-cache and --sdr-cache-recreate)
[-T <sensor type(s)>]
limit sensors to query based on IPMI sensor type.
Examples for IPMI sensor types are 'Fan', 'Temperature', 'Voltage', ...
See the output of the FreeIPMI command 'ipmi-sensors -L' and chapter
'42.2 Sensor Type Codes and Data' of the IPMI 2.0 spec for a full list
of possible sensor types. You can also find the full list of possible
sensor types at https://www.thomas-krenn.com/en/wiki/IPMI_Sensor_Types
The available types depend on your particular server and the available
sensors there.
Multiple sensor types can be specified as a comma-separated list.
[-ST <SEL sensor type(s)>]
limit SEL entries to specific types, run 'ipmi-sel -L' for a list of
types. All sensors are populated to the SEL and per default all sensor
types are monitored. E.g. to limit the sensor SEL types to Memory and
Processsor use -ST 'Memory,Processor'.
[-x <sensor id>]
exclude sensor matching <sensor id>. Useful for cases when unused
sensors cannot be deleted from SDR and are reported in a non-OK state.
Option can be specified multiple times. The <sensor id> is a numeric
value (sensor names are not used as some servers have multiple sensors
with the same name). Use -vvv option to query the <sensor ids>.
[-xT <sensor type(s)>]
exclude sensors based on IPMI sensor type.
Multiple sensor types can be specified as a comma-separated list.
[-xST <SEL sensor type(s)]
exclude SEL entries of specific sensor types.
Multiple sensor types can be specified as a comma-separated list.
[-i <sensor id>]
include only sensor matching <sensor id>. Useful for cases when only
specific sensors should be monitored. Be aware that only for the
specified sensor errors/warnings are generated. Use -vvv option to query
the <sensor ids>.
[-v|-vv|-vvv]
be verbose
(no -v) .. single line output
-v ..... single line output with additional details for warnings
-vv ..... multi line output, also with additional details for warnings
-vvv ..... debugging output, followed by normal multi line output
[-o]
change output format. Useful for using the plugin with other monitoring
software than Nagios or Icinga.
-o zenoss .. create ZENOSS compatible formatted output (output with
underscores instead of whitespaces and no single quotes)
[-D]
change the protocol LAN version. Normally LAN_2_0 is used as protocol
version if not overwritten with this option. Use 'default' here if you
don't want to use LAN_2_0.
[-fc <num fans>]
number of installed fans. If the number of current installed
fans reported by IPMI is not equal than <num fans> then a Warning state
is returned. Please use this option carefully as number of fans and
number of fan sensors can differ!
[--fru]
print the product serial number if it is available in the IPMI FRU data.
For this purpose the tool 'ipmi-fru' is used. E.g.:
IPMI Status: OK (9000096781)
[--assettag]
--fru is mandatory
print the assettag if it is available in the IPMI FRU data.
IPMI Status: OK (9000096781)
Asset Tag: 20200220
[--board]
--fru is mandatory
print additional motherboard informations if it is available in the IPMI FRU data.
IPMI Status: OK (9000096781)
Board Manufacturer: Supermicro
Board Product Name: X10DRW-iT
Board Serial Number: AB123456
[--nosel]
turn off system event log checking via ipmi-sel. If there are
unintentional entries in SEL, use 'ipmi-sel --clear' or the -sx or -xST
option.
[--selonly]
check only system event log checking via ipmi-sel. If there are
unintentional entries in SEL, use 'ipmi-sel --clear' or the -sx or -xST
option.
[--seltail <count>]
limit SEL output to specified count of last messages
[-sx|--selexclude <sel exclude file>]
use a sel exclude file to exclude entries from the system event log.
Specify name and type pipe delimitered in this file to exclude an entry,
for example: System Chassis Chassis Intru|Physical Security
To get valid names and types use the -vvv option and take a look at:
debug output for sel (-vvv is set). Don't use name and type from the
web interface as sensor descriptions are not complete there.
As with the '-xx' option if the first character of a line is '~' the
name is treated as a regular expression.
[-xx|--sexclude <exclude file>]
use an exclude file to exclude sensors, each line specifies an exclude.
Specify name and type pipe delimitered in this file to exclude a sensor,
for example: System Chassis Chassis Intru|Physical Security
If the first character of a line is '~' the name is treated as a regular
expression. E.g. to exclude all sensor names from CPU0 to CPU9:
~CPU[0-9] Temp|Temperature
To get valid names and types use the -vvv option.
[-us|--unify-sensors <unify file>]
use an unify file to unify sensor names. This is an easy way to rename
sensors with given patterns in the file. Once might use this option
to get the same sensor names accross different platforms, e.g. to only
have 'Mainboard Temperature' as sensor name and not 'MB1 Temperature' or 'System Temp'.
Rules in the file follow simple regex patterns e.g.:
^(MB1 Temperature|System Temp)\$/Mainboard Temperature
Temp\$/TEMP
[--nosudo]
turn off sudo usage on localhost or if ipmi host is ommited.
[--nothresholds]
turn off performance data thresholds from output-sensor-thresholds.
[--noentityabsent]
skip sensor checks for sensors that have 'noentityabsent' as event state
[-s <ipmi-sensor output file>]
simulation mode - test the plugin with an ipmi-sensor output redirected
to a file.
[-h]
