UDP
gnmic
supports exporting subscription updates to a UDP server
A UDP output can be defined using the below format in gnmic
config file under outputs
section:
outputs:
output1:
# required
type: udp
# a UDP server address
address: IPAddress:Port
# maximum sending rate, e.g: 1ns, 10ms
rate: 10ms
# number of messages to buffer in case of sending failure
buffer-size:
# export format. json, protobuf, prototext, protojson, event
format: json
# string, one of `overwrite`, `if-not-present`, ``
# This field allows populating/changing the value of Prefix.Target in the received message.
# if set to ``, nothing changes
# if set to `overwrite`, the target value is overwritten using the template configured under `target-template`
# if set to `if-not-present`, the target value is populated only if it is empty, still using the `target-template`
add-target:
# string, a GoTemplate that allow for the customization of the target field in Prefix.Target.
# it applies only if the previous field `add-target` is not empty.
# if left empty, it defaults to:
# {{- if index . "subscription-target" -}}
# {{ index . "subscription-target" }}
# {{- else -}}
# {{ index . "source" | host }}
# {{- end -}}`
# which will set the target to the value configured under `subscription.$subscription-name.target` if any,
# otherwise it will set it to the target name stripped of the port number (if present)
target-template:
# boolean, valid only if format is `event`.
# if true, arrays of events are split and marshaled as JSON objects instead of an array of dicts.
split-events: false
# boolean, if true the message timestamp is changed to current time
override-timestamps: false
# time duration to wait before re-dial in case there is a failure
retry-interval:
# NOT IMPLEMENTED boolean, enables the collection and export (via prometheus) of output specific metrics
enable-metrics: false
# list of processors to apply on the message before writing
event-processors:
A UDP output can be used to export data to an ELK stack, using Logstash UDP input
