[Zeek] Zeek with ELK

[Darren S.]

I read OP question as "I have Zeek running on FreeBSD, what is a
sensible option for shipping logs from the sensor to an Elastic
Stack?" Apologies if it's the wrong read.

In that case I wouldn't want to install either the whole stack nor
even Logstash on the sensor as it alone tends to consume an excessive
amount of memory, not what you want on a sensor. Filebeat (a small
footprint data collector/shipper) is the way to go if you're shipping
remotely.

If Filebeat isn't an option on the platform, maybe explore Fluent Bit:

https://github.com/fluent/fluent-bit
https://fluentbit.io/

Fluent Bit can output directly to Elasticsearch:
https://fluentbit.io/documentation/0.14/output/elasticsearch.html

Even a Fluentd can run with typically lower memory consumption than
Logstash, so perhaps worth exploring both/either:

https://github.com/fluent/fluentd
https://www.fluentd.org/

Fluentd can also output to Elasticsearch:
https://docs.fluentd.org/output/elasticsearch

There are other options for shippers too, such as Syslog-ng:
