IPMI Sensor Input Plugin

Get bare metal metrics using the command line utility 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

# 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 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:

KERNEL=="ipmi*", MODE="660", GROUP="telegraf"
