Enable Performance Logging

In the Confluence Administration → Logging and Profiling section add a new Entry with Package de.griffel.confluence.plugins.plantuml and Log Level INFO.



After that you should see the rendering performance for each plantuml macro in the confluence.home/logs/atlassian-confluence.log File:

2016-04-08 13:52:53,161 INFO [...] [confluence.plugins.plantuml.PlantUmlMacro] executeInternal Rendering UML diagram on page Foo:Bar took 375 ms.


"Error: dot cannot generated PNG file. Check your dot installation.

Check your installation using PlantUML Version Information.

Ensure that the correct version of Graphviz will be used either by setting the environment variable GRAPHVIZ_DOT or by adding dot to the search path.

German umlauts or other non ASCII characters are not shown correctly in generated graphs

Usually, this is a problem with the installation of Confluence or Graphviz.

  1. Check your graphviz installation.

    1. Create a file test.dot with the following content:

      digraph test {
   state [label="insert characters that are not shown correctly"]
}

    2. Let graphviz create a the image. Do this as user who runs Confluence and use the same Graphviz version as Confluence. You can check this as described in PlantUML Version Information.

      dot -Tpng test.dot -otest.png
    3. Check the created test.png. If the image is correct check Confluence. If not, you have to correct your Graphviz installatoin.
  2. Verify that all parts of your Confluence installation use the correct encoding which should be UTF-8.
    • Tomcat connector in conf/server.xml: URIEncoding="UTF-8"
    • Java command line argument: -Dfile.encoding=UTF-8
