Is there the documents about built-in variables on Logstash configuration?

(Takeo Fujiwara) #1

I need the IP address of source host that send data to Logstash input.
I wonder if there is the documents about some built-in(?) variables that can be used input plug-in on Logstash configuration.
Is there that somewhere? where?

Sometimes the documentation of input plugins describes which fields are set, but don't count on it. You can make experiments, read the source code, or ask specific questions here.
