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