Log forwarding helpers.
|
|
|
|
DECNET is agnostic to what receives logs — any TCP/UDP listener works
|
|
(Logstash, Splunk, Graylog, netcat, etc.).
|
|
|
|
Each service plugin handles the actual forwarding by injecting the
|
|
LOG_TARGET environment variable into its container. This module provides
|
|
shared utilities for validating and parsing the log_target string.
