Aquaero plugins for Munin

Aquaero My home servers are water cooled, I use the Aquaero device for monitoring the status of the cooling system. (fan speed, temperature and water flow).

The Aquaero is a monitoring system made by Aquacomputer, an German watercooling hardware manufacturer.

This monitoring system is working on Debian GNU/Linux and the source code of the monitoring program is available under the terms of the LGPL License.

You can find the command ligne monitoring system here : aquaero downloads.

I’ve wrote an C++ plugin for Munin, in order to get the watercooling status monitored.

Fan speed Water flow Temperature

Setup

Fallow thoses instructions in order to build and setup the plugin :

$ su
# cd /usr/src
# wget http://www.aqua-computer.de/download/aquaero_software/aeinfo-2.1-src.tar.gz
# tar xzf aeinfo-2.1-src.tar.gz
# cd aeinfo-2.1-src/
# wget http://svn.csquad.org/aquaero_munin/munin.cpp
# g++ -Wno-deprecated munin.cpp -lusb -o munin
# mv munin /usr/share/munin/plugins/aquaero
# cd /etc/munin/plugins
# ln -s /usr/share/munin/plugins/aquaero aquaero_fan
# ln -s /usr/share/munin/plugins/aquaero aquaero_temp
# ln -s /usr/share/munin/plugins/aquaero aquaero_flow
# echo < > /etc/munin/plugin-conf.d/munin-node
[aquaero_*]
user root
EOF
# /etc/init.d/munin-node restart

Enjoy and feel free to report bugs.

    I’m thinking about picking this device up. Does the software work well under linux? It’s all in German so I have no idea if it’s even up-to-date or working with the latest firmware. How has your experience been with it? Are you able to control each fan from the command line? Can you set it so that the fans change speed based on a temperature probe? Can you easily poll the device for Temp and RPM information for parsing to Gkrellm and the like?

    Thanks for your help!

    Hi Antioch,

    The software are working on Linux, two software are available :

    * aeinfo : command line interface ;
    * aquaerod : web user interface ;

    The CLI and the WebUI are very basic but works.

    The main problem with Aquaero is the awful mix between German and English.

    The Website/Shop is not always translated, information returned by the device is not translated and the manual is in German (you can grab a English version in PDF).
    Personally I don’t care because I can read (a little) German but many people are stopped by that.

    I did not try to update the firmware.

    You can set the fan speed by cli and webui.

    For monitoring, I use conky, and I read the values returned by the cli.
    You may do the same with gkrellm.

    Aquaero is a good monitoring device, there are other monitoring device like TMS-200 manifactured by Koolance.

    You can check the review made by OCTeam if you read French :
