These actions are unsupported since the changes are to the OS, not the Checkmk software. This behavior was observed only on SUSE Linux Enterprise Server 15 (SLES15) with Service Pack 4. |
Problem
You may encounter an issue where the characters in their your Checkmk service graphs appear incorrect and are displayed as follows:
This issue occurs due to the fonts located in the /usr/share/ directory of both openSUSE and SUSE Linux Enterprise (SLE) distributions.
. This is caused by the default font pack that SLES15 SP4 uses.
Solution
To resolve this, you can execute the following commands either as a normal Linux user or as root:
Stop the site
Code Block language bash theme RDark
...
root@mylinuxhost# omd stop
...
<mysite>.
Change directory to /usr/share/
Code Block language bash theme RDark root@mylinuxhost# cd /usr/share
...
/.
Create a backup of the original fonts file
Code Block language bash theme RDark root@mylinuxhost:/usr/share# mv fonts fonts.bak
...
.
Install zypper
Code Block language bash theme RDark root@mylinuxhost:/usr/share# zypper install -f google-opensans-fonts
...
.
Start the site
Code Block language bash theme RDark root@mylinuxhost:/usr/share# omd start
...
<mysite>.
After the Checkmk site has been restarted, the service graphs should display as expected.
