I am trying to run logstash on Windows.
Just installed Java. Then ran logstash as descirbed here.
Also validated the java install as described in the same page.
And then when I run logstash manually, it first started, but then immediately shutdown, spitting this right on my face.
What am I missing?

The message "No config files found in path" indicates that when logstash had finished reading all the configuration files it did not have any configuration. That could because your syslog.conf is empty, or it contains invalid UTF-8 characters (so it was skipped), or possibly logstash was unable to read it.
If you add --log.level debug to the command line you should get a "Reading config file" message for that file. If you do not then logstash was unable to find it (e.g. it does not exist or the directory is not readable by the user running logstash).
