telegraf <flags>
telegraf <flags>
The flags are:
-config <file> configuration file to load
-test gather metrics once, print them to stdout, and exit
-sample-config print out full sample configuration to stdout
-config-directory directory containing additional *.conf files
-input-filter filter the input plugins to enable, separator is :
-output-filter filter the output plugins to enable, separator is :
-usage print usage for a plugin, ie, 'telegraf -usage mysql'
