What does "Incorrect date format" mean with logs?

We are new to Dynatrace and for our log files (log4j and access), we see "(Incorrect date format)" on the Log Files screen. Does anyone know what that means and how we correct it? Our file names are like "FOO01.bar_8443.20180228.xml". We are unable to select the file in Dynatrace, presumably from this error.

not sure if dynamics means dynatrace in this post 😉 anyway, incorrect date format means that log structure contains unrecognized timestamps

Thanks for the reply. I fixed the typos. Any idea what format we would need to use to correct it?

It is most likely due to XML format that is not supported currently.

What are the supported log file formats? We were told some that are not supported, but none which is supported.

What are the
Dynatrace supported log formats? we are also facing the incorrect date format
issue with one of our application log. Log file name
is MSTRLog10042018_1.log but its contains XML tags(PFA screenshot).

Does dynatrace
support xml log entry format?


Ajit, the help topic Pawel mentioned in the first post is still valid. Unfortunately the XML structured files are not supported as of now.


  • Any plain text log file as long as it contains a timestamp that meets these basic requirements:
  • A timestamp must appear at the beginning of each log entry.
