Beat script processor to filter out IPv6
View beat.yml
- script:
# This uses a Beat script processor to include only ipv4 addresses
# in the host.ip field. This would need to placed after the add_host_metadata
# processor.
# It would be a lot more efficient to have add_host_metadata allow controlling
# what addresses were included because this has to execute for every event.

Routing Filebeat data to a Fleet integration data stream

DRAFT: Routing Filebeat data to a Fleet integration data stream

This is an unofficial tutorial that may be useful to users that are in the process of migrating to to Elastic Agent and Fleet. It explains the steps to route some Filebeat data into a data stream managed by a Fleet integration package.

Install the Fleet integration

Installing a Fleet integration sets up all of its data streams and dashboards. There are two methods to install. In these examples we install the Hashicorp Vault 1.3.1 integration.

Use Kibana (easiest)

Adding event.ingested and lag calculations to Winlogbeat events

Adding event.ingested and lag calculations to Winlogbeat events

Create an Ingest Pipeline that will add four fields:

  • event.ingested - Time when the event was processed by Elasticsearch.
  • - Time difference in milliseconds between @timestamp and event.created. This measures how long it took for Winlogbeat read the event from the event log (for WEC this includes the delivery time from forwarder to collector).
  • event.lag.ingest - Time difference in milliseconds between event.created and event.ingested. This measures the time between Winlogbeat reading the event (time when it "created" the document) to when it was written to Elasticsearch.
