Method: LogStash::Event#sprintf

Defined in:
lib/logstash/event.rb

#sprintf(format) ⇒ Object

sprintf. This could use a better method name. The idea is to take an event and convert it to a string based on any format values, delimited by %foo where ‘foo’ is a field or metadata member.

For example, if the event has type == “foo” and host == “bar” then this string:

"type is %{type} and source is %{host}"

will return

"type is foo and source is bar"

If a %name value is an array, then we will join by ‘,’ If a %name value does not exist, then no substitution occurs.
