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
or with the version 2 schema:
ipmitool sdr elist
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"
##
## 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
##
## optionally force session privilege level. Can be CALLBACK, USER, OPERATOR, ADMINISTRATOR
# privilege = "ADMINISTRATOR"
##
## 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"
## Schema Version: (Optional, defaults to version 1)
metric_version = 2
Measurements
Version 1 schema:
- ipmi_sensor:
- tags:
- name
- unit
- host
- server (only when retrieving stats from remote servers)

Version 2 schema:
- ipmi_sensor:

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"
Alternatively, it is possible to use sudo. You will need the following in your telegraf config:
[[inputs.ipmi_sensor]]
use_sudo = true
You will also need to update your sudoers file:
$ visudo
# Add the following line:
Cmnd_Alias IPMITOOL = /usr/bin/ipmitool *
telegraf ALL=(root) NOPASSWD: IPMITOOL
Defaults!IPMITOOL !logfile, !syslog, !pam_session
