ipmimonitoring 0.1.1

A python wrapper for libipmimonitoring from freeipmi

Python ipmimonitoring

This module is a Python wrapper for libipmimonitoring from https://www.gnu.org/software/freeipmi/ .

Requirements

libipmimonitoring must be installed, on debian install it with:

sudo apt install -y libipmimonitoring6

Install ipmimonitoring either from source or via PyPi:

pip install impimonitoring

Test application

ipmimonitoring/__main__.py contains a simple tool which reads sensor data, similar to ipmi-sensors from the freeipmi-tools package which can be run like this:

python -m ipmimonitoring [arguments]

The output will look like this:

Reading in-band sensors from the local BMC

Read sensors from the local machine using /dev/impiN. Normally opening that device requires root permissions:

sudo python -m ipmimonitoring

alternately, change the permissions so that your user can access the device:

sudo chown $USER /dev/impi*
python -m ipmimonitoring

Reading out-of-band sensors from a remote BMC

It's also possible to access a remote BMC over the network. You need to provide a hostname, username and password.

python -m ipmimonitoring --hostname=host --username=user --password=password

Flags

Most parameters supported by libipmimonitoring should be possible to set using the command line. A few additional ones are listed below.

Keep reading IPMI data forever. Optionally specify how many seconds to wait between each read. Default 1 second.

python -m ipmimonitoring --follow[=seconds]

The table output is produced using the prettytable module (https://github.com/prettytable/prettytable). Any format supported by prettytable (currently text, html, json, csv, latex and mediawiki) can be used with this tool.

python -m ipmimonitoring --table[=format]]

Output JSON format with the field names as the keys instead of the table headings. Optionally pass the number of spaces to indent the JSON data for a prettier readout.

python -m ipmimonitoring --json[=indent]

License

All the code written by me is licensed under the MIT license.

Note that libimpimonitoring itself is licensed under GPLv2 or later, but since libipmonitoring is distributed as a Debian package it should be ok to use it the way this Python module does without tainting it. Or that is how I read this paragraph from the GPLv2 license:

However, as a special exception, the source code distributed need
not include anything that is normally distributed (in either
source or binary form) with the major components (compiler,
kernel, and so on) of the operating system on which the executable
runs, unless that component itself accompanies the executable

Also, as far as I know APIs are not copyrightable, so the headers and APIs in wrapper.py and all enums should be ok to distribute under a MIT license.
