PSU Energy AC - IPMI machine

What it does

This metric provider uses the IPMI protocol to get sensor data from the current power draw of the system. This can either come from a sensor that is accessible via ACPI or via other means through the libsensors.

Install

You will need sudo apt-get install freeipmi-tools ipmitool installed on a Debian based distro. This installation step will automatically happen if you normally install the tool with the ./install_linux.sh script.

The install script will also set a sudoers.d entry so that the underlying program /usr/sbin/ipmi-dcmi --get-system-power-statistics can execute without password request.

On some systems you will need to run the detect program first sudo sensors-detect which looks at all the chips in your computer and creates the config file.

Classname

  • PsuEnergyAcIpmiMachineProvider

Input Parameters

  • -i: interval in milliseconds. By default the measurement interval is 100 ms.
> ./ipmi-get-machine-energy-stat.sh -i 100

Output

This metric provider prints to stdout a continuous stream of data every interval milliseconds till it is stopped with sigkill or sigint (Ctrl-c). The format of the data is as follows:

TIMESTAMP READING

Where:
