Debug
editDebug
editBy default, APM Server sends all its output to syslog. When you run APM Server in
the foreground, you can use the -e command line flag to redirect the output to
standard error instead. For example:
apm-server -e
The default configuration file is apm-server.yml (the location of the file varies by
platform). You can use a different configuration file by specifying the -c flag. For example:
apm-server -e -c myapm-serverconfig.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 APM Server
with the publish selector like this:
apm-server -e -d "publish"
If you want all the debugging output (fair warning, it’s quite a lot), you can
use *, like this:
apm-server -e -d "*"
