A customer may run into an issue where the characters in their Checkmk graphs are incorrect and display like this:
This is caused by the fonts located in /usr/share/ of both openSUSE and SUSE Linux Enterprise (SLE) distributions.
To fix this, you run the following commands as a normal Linux user, or as root.
sudo omd stop <SITENAME> cd /usr/share/ sudo mv fonts fonts.bak sudo zypper install -f google-opensans-fonts sudo omd start <SITENAME>
