-# freeipmi.plugin
-
-Netdata has a [freeipmi](https://www.gnu.org/software/freeipmi/) plugin.
-
-> FreeIPMI provides in-band and out-of-band IPMI software based on the IPMI v1.5/2.0 specification. The IPMI
-> specification defines a set of interfaces for platform management and is implemented by a number vendors for system
-> management. The features of IPMI that most users will be interested in are sensor monitoring, system event monitoring,
-> power control, and serial-over-LAN (SOL).
-
-## Installing the FreeIPMI plugin
-
-When using our official DEB/RPM packages, the FreeIPMI plugin is included in a separate package named
-`netdata-plugin-freeipmi` which needs to be manually installed using your system package manager. It is not
-installed automatically due to the large number of dependencies it requires.
-
-When using a static build of Netdata, the FreeIPMI plugin will be included and installed automatically, though
-you will still need to have FreeIPMI installed on your system to be able to use the plugin.
-
-When using a local build of Netdata, you need to ensure that the FreeIPMI development packages (typically
-called `libipmimonitoring-dev`, `libipmimonitoring-devel`, or `freeipmi-devel`) are installed when building Netdata.
-
-### Special Considerations
-
-Accessing IPMI requires root access, so the FreeIPMI plugin is automatically installed setuid root.
-
-FreeIPMI does not work correctly on IBM POWER systems, thus Netdata’s FreeIPMI plugin is not usable on such systems.
-
-If you have not previously used IPMI on your system, you will probably need to run the `ipmimonitoring` command as root
-to initiailze IPMI settings so that the Netdata plugin works correctly. It should return information about available
-seensors on the system.
-
-In some distributions `libipmimonitoring.pc` is located in a non-standard directory, which
-can cause building the plugin to fail when building Netdata from source. In that case you
-should find the file and link it to the standard pkg-config directory. Usually, running `sudo ln -s
-/usr/lib/$(uname -m)-linux-gnu/pkgconfig/libipmimonitoring.pc/libipmimonitoring.pc /usr/lib/pkgconfig/libipmimonitoring.pc`
-resolves this issue.
-
-## Metrics
-
-The plugin does a speed test when it starts, to find out the duration needed by the IPMI processor to respond. Depending
-on the speed of your IPMI processor, charts may need several seconds to show up on the dashboard.
-
-Metrics grouped by *scope*.
-
-The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
-
-### global
-
-These metrics refer to the monitored host.
-
-This scope has no labels.
-
-Metrics:
-
-| Metric | Dimensions | Unit |
-|----------|:----------:|:------:|
-| ipmi.sel | events | events |
-
-### sensor
-
-These metrics refer to the sensor.
-
-Labels:
-
-| Label | Description |
-|-----------|-----------------------------------------------------------------------------------------------------------------|
-| sensor | Sensor name. Same value as the "Name" column in the `ipmi-sensors` output. |
-| type | Sensor type. Same value as the "Type" column in the `ipmi-sensors` output. |
-| component | General sensor component. Identified by Netdata based on sensor name and type (e.g. System, Processor, Memory). |
-
-Metrics:
-
-| Metric | Dimensions | Unit |
-|-----------------------------|:-----------------------------------:|:----------:|
-| ipmi.sensor_state | nominal, critical, warning, unknown | state |
-| ipmi.sensor_temperature_c | temperature | Celsius |
-| ipmi.sensor_temperature_f | temperature | Fahrenheit |
-| ipmi.sensor_voltage | voltage | Volts |
-| ipmi.sensor_ampere | ampere | Amps |
-| ipmi.sensor_fan_speed | rotations | RPM |
-| ipmi.sensor_power | power | Watts |
-| ipmi.sensor_reading_percent | percentage | % |
-
-## Alarms
-
-There are 2 alarms:
-
-- The sensor is in a warning or critical state.
-- System Event Log (SEL) is non-empty.
-

-
- Linux kernel module for IPMI is CPU hungry.
- On Linux run this to lower kipmiN CPU utilization:
- # echo 10 > /sys/module/ipmi_si/parameters/kipmid_max_busy_us
-
- or create: /etc/modprobe.d/ipmi.conf with these contents:
- options ipmi_si kipmid_max_busy_us=10
-
- For more information:
- https://github.com/netdata/netdata/tree/master/collectors/freeipmi.plugin
-```
-
-You can set these options in `/etc/netdata/netdata.conf` at this section:
-
-```
-[plugin:freeipmi]
- update every = 5
- command options =
-```
-
-Append to `command options =` the settings you need. The minimum `update every` is 5 (enforced internally by the
-plugin). IPMI is slow and CPU hungry. So, once every 5 seconds is pretty acceptable.
-
-## Ignoring specific sensors
-
-Specific sensor IDs can be excluded from freeipmi tools by editing `/etc/freeipmi/freeipmi.conf` and setting the IDs to
-be ignored at `ipmi-sensors-exclude-record-ids`. **However this file is not used by `libipmimonitoring`** (the library
-used by Netdata's `freeipmi.plugin`).
-
-So, `freeipmi.plugin` supports the option `ignore` that accepts a comma separated list of sensor IDs to ignore. To
-configure it, edit `/etc/netdata/netdata.conf` and set:
-
-```
-[plugin:freeipmi]
- command options = ignore 1,2,3,4,...
-```
-
-To find the IDs to ignore, run the command `ipmimonitoring`. The first column is the wanted ID:
-
-```
-ID | Name | Type | State | Reading | Units | Event
-1 | Ambient Temp | Temperature | Nominal | 26.00 | C | 'OK'
-2 | Altitude | Other Units Based Sensor | Nominal | 480.00 | ft | 'OK'
-3 | Avg Power | Current | Nominal | 100.00 | W | 'OK'
-4 | Planar 3.3V | Voltage | Nominal | 3.29 | V | 'OK'
-5 | Planar 5V | Voltage | Nominal | 4.90 | V | 'OK'
-6 | Planar 12V | Voltage | Nominal | 11.99 | V | 'OK'
-7 | Planar VBAT | Voltage | Nominal | 2.95 | V | 'OK'
-8 | Fan 1A Tach | Fan | Nominal | 3132.00 | RPM | 'OK'
-9 | Fan 1B Tach | Fan | Nominal | 2150.00 | RPM | 'OK'
-10 | Fan 2A Tach | Fan | Nominal | 2494.00 | RPM | 'OK'
-11 | Fan 2B Tach | Fan | Nominal | 1825.00 | RPM | 'OK'
-12 | Fan 3A Tach | Fan | Nominal | 3538.00 | RPM | 'OK'
-13 | Fan 3B Tach | Fan | Nominal | 2625.00 | RPM | 'OK'
-14 | Fan 1 | Entity Presence | Nominal | N/A | N/A | 'Entity Present'
-15 | Fan 2 | Entity Presence | Nominal | N/A | N/A | 'Entity Present'
-...
-```
-
-## Debugging
-
-You can run the plugin by hand:
-
-```sh
-# become user netdata
-sudo su -s /bin/sh netdata
-
-# run the plugin in debug mode
-/usr/libexec/netdata/plugins.d/freeipmi.plugin 5 debug
-```
-
-You will get verbose output on what the plugin does.
-
-## kipmi0 CPU usage
-
-There have been reports that kipmi is showing increased CPU when the IPMI is queried. To lower the CPU consumption of
-the system you can issue this command:
-
-```sh
-echo 10 > /sys/module/ipmi_si/parameters/kipmid_max_busy_us
-```
-
-You can also permanently set the above setting by creating the file `/etc/modprobe.d/ipmi.conf` with this content:
-
-```sh
-# prevent kipmi from consuming 100% CPU
-options ipmi_si kipmid_max_busy_us=10
-```
-
-This instructs the kernel IPMI module to pause for a tick between checking IPMI. Querying IPMI will be a lot slower
-now (e.g. several seconds for IPMI to respond), but `kipmi` will not use any noticeable CPU. You can also use a higher
-number (this is the number of microseconds to poll IPMI for a response, before waiting for a tick).
-
-If you need to disable IPMI for Netdata, edit `/etc/netdata/netdata.conf` and set:
-
-```
-[plugins]
- freeipmi = no
-```
