|Compatibility||Incompatible - Manual interaction might be required|
This release comes with a major change to the Check_MK Appliance Firmware. It
migrates the operating system to a 64-bit architecture. This gives us benefits
in memory management and ensures the platform is ready for the future.
The migration of sites from other linux systems will also be faster since no
architecture migrations are needed anymore.
For standard environments the update procedure is straight forward, just like
other regular firmware updates. However, there are some things you should be
- Install the Check_MK Firmware 1.2.1 or newer first!
Before starting the firmware update to 1.3.0 (or newer) you need to update your
appliance to firmware 1.2.1 or newer to ensure a flawless update to the 64-bit
This is very important! If you try to update to 1.3.0 from a version older than
1.2.1 you may end up with a bricked device which can only be fixed by us.
- The Check_MK rail1 is not 64-bit ready
If you own a Check_MK rail1, you will need to stick with the 1.2.x releases,
because the hardware platform is 32-bit. All following 1.2.x releases we may
release in the future will be maintenance releases for the old 32-bit platform.
You will receive bug fixes and security patches with these releases.
A follow-up model for the Check_MK rail1, which will have a 64-bit architecture,
will be announced in the near future.
- Update of Check_MK sites
If you update your monitoring sites to versions which are shipped with the
firmware (currently 1.2.6p15), your sites will be fully migrated to 64-bit.
When your sites use any other version, they will not start after the firmware
update. To make them start again, you first need to upload matching 64-bit
Check_MK versions and eventually update your sites to a 64-bit version.
After completing this step, you will be able to start your site from the
Site Management page.
These are the first versions having 64-bit support on the appliance:
innovation / master branch:
The update procedure will show you a list of your sites and their versions
before the update is being started.
- Custom software
If you installed custom software on your device, which is not compatible
to the new 64-bit architecture, you will be warned about this before the
update is started. You will have to clean this up manually before you
