# Telegraf ipmi plugin
Get bare metal metrics using the command line utility `ipmitool`
see ipmitool(https://sourceforge.net/projects/ipmitool/files/ipmitool/)
The plugin will use the following command to collect remote host sensor stats:
ipmitool -I lan -H 192.168.1.1 -U USERID -P PASSW0RD sdr
## Measurements
- ipmi_sensor:
* Tags: `server`,`host`
* Fields:
- status
- value
## Configuration
```toml
[[inputs.ipmi]]
## specify servers via a url matching:
## [username[:password]@][protocol[(address)]]
## e.g.
## root:passwd@lan(127.0.0.1)
##
servers = ["USERID:PASSW0RD@lan(10.20.2.203)"]
```
## Output
> ipmi_sensor,host=10.20.2.203,inst=Ambient\ Temp status=1i,value=20 1458488465012559455
