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