Great news, there is an official commitment to add support for certain ARM architectures by Checkmk: Checkmk – our road to ARM support. This could mean, that at some point the Raspberry Pi 5 and subsequent models could use native Checkmk packages. In the meantime, you can continue to vote for the feature request: https://features.checkmk.com/suggestions/297317/arm-support-for-the-cee-and-cme.

Unfortunately, due to native ARM support on the horizon we have decided to retire this project (thank you @martux69 for all your hard work supporting arm64 over all the years). This decision was based on the fact that keeping up with upstream changes has recently become increasingly time-consuming, additionally other (personal) things have become more important, so that there is no longer enough time.

There is, however, a fork of the project being maintained on a "best effort" basis at https://github.com/FloTheSysadmin/check-mk-arm.

If anyone would like to take over, please reach out.

Checkmk

Tips & General Information

Errors during installation
dpkg: error processing package check-mk-raw-* (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 check-mk-raw-*

That's perfectly fine. Run apt-get install -f and the installation should complete successfully.

Raspberry Pi: use an HDD/SSD when running Checkmk

The rrdcached issues many small write requests which may harm your SD card, see: https://forum.checkmk.com/t/checkmk-on-raspberry-pi/27760/4

Raspberry Pi: reduce the number of apache processes

Go to Setup > General > Global settings > Site Management and reduce the number at Apache process tuning to 5.

Oracle Cloud Infrastructure: access web interface

In case of issues accessing the Checkmk web interface, check the pre-defined iptables rules, see: https://blog.meinside.dev/When-Oracle-Clouds-Ubuntu-Instance-Doesnt-Accept-Connections-to-Ports-Other-than-22/

Build Checkmk from sources

# build a specific version of Checkmk targeting Debian 32-bit, e.g.: 2.2.0p1
INSTALL_DEPENDENCIES=1 bash build_check_mk_debian_32bit.sh <version>

# build a specific version of Checkmk targeting Ubuntu 64-bit, e.g.: 2.1.0p21
INSTALL_DEPENDENCIES=1 bash build_check_mk_ubuntu_64bit.sh <version>

Install Checkmk to your device

Build or get a deb package that targets your system and install it as shown below, then follow the official user guide to set everything up.

dpkg -i check-mk-raw-*.deb
apt-get update && apt-get install -f
