Usage:
check_ipmi_sensor -H <hostname>
[-f <FreeIPMI config file> | -U <username> -P <password> -L <privilege level>]
[-O <FreeIPMI options>] [-b] [-T <sensor type(s)>] [-x <sensor id>]
[-xT <sensor type(s)>] [-xST <SEL sensor type(s)]

}
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).
[-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. 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 fans that should be active. If the number of current active
fans reported by IPMI is smaller than <num fans> then a Warning state
is returned.
[--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)
[--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.
[-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.
[-xx|--sexclude <exclude file>]
use an exclude file to exclude sensors.
Specify name and type pipe delimitered in this file to exclude a sensor,
To get valid names and types use the -vvv option.
[--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]

[-V]
