# IPMI Sensor Input Plugin
Get bare metal metrics using the command line utility
[`ipmitool`](https://sourceforge.net/projects/ipmitool/files/ipmitool/).
If no servers are specified, the plugin will query the local machine sensor stats via the following command:
```
ipmitool sdr
```
When one or more servers are specified, the plugin will use the following command to collect remote host sensor stats:
```
ipmitool -I lan -H SERVER -U USERID -P PASSW0RD sdr
```
### Configuration
```toml
# Read metrics from the bare metal servers via IPMI
[[inputs.ipmi_sensor]]
## optionally specify the path to the ipmitool executable
# path = "/usr/bin/ipmitool"
#
## optionally specify one or more servers via a url matching
## [username[:password]@][protocol[(address)]]
## e.g.
## root:passwd@lan(127.0.0.1)
##
## if no servers are specified, local machine sensor stats will be queried
##
# servers = ["USERID:PASSW0RD@lan(192.168.1.1)"]
## Recomended: use metric 'interval' that is a multiple of 'timeout' to avoid
## gaps or overlap in pulled data
interval = "30s"
## Timeout for the ipmitool command to complete. Default is 20 seconds.
timeout = "20s"
```
### Measurements
- ipmi_sensor:
- tags:
- name
- unit
- server (only when retrieving stats from remote servers)
- fields:
- status (int)
- value (float)
#### Permissions
When gathering from the local system, Telegraf will need permission to the
impi 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`:
```
KERNEL=="ipmi*", MODE="660", GROUP="telegraf"
```
### Example Output
When retrieving stats from a remote server:
```
