Load Statistics graph weird encoding #javamelody #font #font_issue


Problem:

If we deploy our application (*.war) on a customer's infrastructure, all texts in graphs are broken. The very same montioring of the application works when deployed in our local infrastructure. All "plain" texts are rendered corretly.
  • Only graphs are affected
  • The problem seems to be environment specific
I've no clue what we need to do/install/change on the customers environment to be able to have proper texts in graphs again. When we first installed the application the graphs worked. Our customers administrators have updated the system / installed patches since then but cannot tell what they've done exactly. I've never seen java melody showing broken graphs before.
Broken Dashboard:
javamelody_charset_graph_error
Betriebssystem: | Linux, 3.10.0-693.2.2.el7.x86_64 , amd64/64 (16 Kerne)
Java: | Java(TM) SE Runtime Environment, 1.8.0_111-b14
JVM: | Java HotSpot(TM) 64-Bit Server VM, 25.111-b14, mixed mode
Server: | Apache Tomcat/8.0.36
Same Application works fine in our local test environment:
Betriebssystem: | Linux, 4.4.0-78-generic , amd64/64 (16 Kerne)
Java: | Java(TM) SE Runtime Environment, 1.8.0_121-b13
JVM: | Java HotSpot(TM) 64-Bit Server VM, 25.121-b13, mixed mode

Solution:

fc-list
yum install dejavu-sans-fonts.noarch dejavu-sans-mono-fonts.noarch
After installation, restart application.
