This functionality is in beta and is subject to change. The design and
code is considered to be less mature than official GA features. Elastic will
take a best effort approach to fix any issues, but beta features are not
subject to the support SLA of official GA features.

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