+## Common Issues
+
+> ### When I look at fluentd logs, everything looks fine but no journal logs are read
+
+This is commonly caused when the user running fluentd does not have enough permisions
+to read the systemd journal.
+
+Acording to the [systemd documentation](https://www.freedesktop.org/software/systemd/man/systemd-journald.service.html):
+> Journal files are, by default, owned and readable by the "systemd-journal" system group but are not writable. Adding a user to this group thus enables her/him to read the journal files.
+
+
 ## Dependencies
 
 This plugin depends on libsystemd
 
 ## Running the tests
 
 To run the tests with docker on several distros simply run `rake`
 
 For systems with systemd installed you can run the tests against your installed libsystemd with `rake test`
