# IPMI Sensor Input Plugin
This plugin gathers metrics from the
[Intelligent Platform Management Interface][ipmi_spec] using the
[`ipmitool`][ipmitool] command line utility.
> [!IMPORTANT]
> The `ipmitool` requires access to the IPMI device. Please check the
> [permission section](#permissions) for possible solutions.
⭐ Telegraf v0.12.0
🏷️ hardware, system
💻 all
[ipmi_spec]: https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/ipmi-intelligent-platform-mgt-interface-spec-2nd-gen-v2-0-spec-update.pdf
[ipmitool]: https://github.com/ipmitool/ipmitool
## Global configuration options <!-- @/docs/includes/plugin_config.md -->
In addition to the plugin-specific configuration settings, plugins support
additional global and plugin configuration settings. These settings are used to
modify metrics, tags, and field or create aliases and configure ordering, etc.
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.
[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins
## Configuration
```toml @sample.conf
# Read metrics from the bare metal servers via IPMI
[[inputs.ipmi_sensor]]
## Specify the path to the ipmitool executable
# path = "/usr/bin/ipmitool"
## Use sudo
## Setting 'use_sudo' to true will make use of sudo to run ipmitool.
## Sudo must be configured to allow the telegraf user to run ipmitool
## without a password.
# use_sudo = false
## Servers
## Specify one or more servers via a url. If no servers are specified, local
## machine sensor stats will be queried. Uses the format:
## [username[:password]@][protocol[(address)]]
## e.g. root:passwd@lan(127.0.0.1)
# servers = ["USERID:PASSW0RD@lan(192.168.1.1)"]
## Session privilege level
## Choose from: CALLBACK, USER, OPERATOR, ADMINISTRATOR
# privilege = "ADMINISTRATOR"
## Timeout
## Timeout for the ipmitool command to complete.
# timeout = "20s"
## Metric schema version
## See the plugin readme for more information on schema versioning.
# metric_version = 1
## Sensors to collect
## Choose from:
## * sdr: default, collects sensor data records
## * chassis_power_status: collects the power status of the chassis
## * dcmi_power_reading: collects the power readings from the Data Center Management Interface
# sensors = ["sdr"]
## Hex key
## Optionally provide the hex key for the IMPI connection.
# hex_key = ""
## Cache
## If ipmitool should use a cache
## Using a cache can speed up collection times depending on your device.
# use_cache = false
## Path to the ipmitools cache file (defaults to OS temp dir)
## The provided path must exist and must be writable
# cache_path = ""
```
If no servers are specified, the plugin will query the local machine sensor
stats via the following command:
```sh
ipmitool sdr
```
or with the version 2 schema:
```sh
ipmitool sdr elist
```
When one or more servers are specified, the plugin will use the following
command to collect remote host sensor stats:
```sh
ipmitool -I lan -H SERVER -U USERID -P PASSW0RD sdr
```
Any of the following parameters will be added to the aforementioned query if
they're configured:
```sh
-y hex_key -L privilege
```
## Sensors
By default the plugin collects data via the `sdr` command and returns those
values. However, there are additonal sensor options that be call on:
- `chassis_power_status` - returns 0 or 1 depending on the output of
`chassis power status`
- `dcmi_power_reading` - Returns the watt values from `dcmi power reading`
These sensor options are not affected by the metric version.
## Metrics
Version 1 schema:
- ipmi_sensor:
- tags:
- name
- unit
- host
- server (only when retrieving stats from remote servers)
- fields:
- status (int, 1=ok status_code/0=anything else)
- value (float)
Version 2 schema:
- ipmi_sensor:
- tags:
- name
- entity_id (can help uniquify duplicate names)
- status_code (two letter code from IPMI documentation)
- status_desc (extended status description field)
- unit (only on analog values)
- host
- server (only when retrieving stats from remote)
- fields:
- value (float)
### Permissions
When gathering from the local system, Telegraf will need permission to the
ipmi device node. When using udev you can create the device node giving
`rw` permissions to the `telegraf` user by adding the following rule to
`/etc/udev/rules.d/52-telegraf-ipmi.rules`:
```sh
KERNEL=="ipmi*", MODE="660", GROUP="telegraf"
```
Alternatively, it is possible to use sudo. You will need the following in your
telegraf config:
```toml
[[inputs.ipmi_sensor]]
use_sudo = true
```
You will also need to update your sudoers file:
```bash
$ visudo
# Add the following line:
Cmnd_Alias IPMITOOL = /usr/bin/ipmitool *
telegraf ALL=(root) NOPASSWD: IPMITOOL
Defaults!IPMITOOL !logfile, !syslog, !pam_session
```
## Example Output
### Version 1 Schema
When retrieving stats from a remote server:
```text
