By default, Filebeat sends all its output to syslog. When you run Filebeat in
the foreground, you can use the
-e command line flag to redirect the output to
standard error instead. For example:
The default configuration file is filebeat.yml (the location of the file varies by
platform). You can use a different configuration file by specifying the
-c flag. For example:
filebeat -e -c myfilebeatconfig.yml
You can increase the verbosity of debug messages by enabling one or more debug
selectors. For example, to view publisher-related messages, start Filebeat
filebeat -e -d "publisher"
If you want all the debugging output (fair warning, it’s quite a lot), you can
*, like this:
filebeat -e -d "*"
