Build

Build beats

go build -o filebeat filebeat/filebeat.go
go build -o functionbeat functionbeat/functionbeat.go
go build -o winlogbeat winlogbeat/winlogbeat.go
go build -o packetbeat packetbeat/packetbeat.go

Usage

In this section, you can use the sample config file in the directory [./sample/config/], or you can create it as follow steps.

example

Add following configuration to beat.yml

output.pulsar:
  url: "pulsar://localhost:6650"
  topic: my_topic
  name: test123

Start filebeat

./filebeat modules enable system
./filebeat modules list
./filebeat -c filebeat.yml -e

Build and test with docker

Requirements

• Docker

Build Beat images

docker build -t pulsar-beat .

Create network

docker network create pulsar-beat

Start Pulsar service

docker run -d -it --network pulsar-beat -p 6650:6650 -p 8080:8080 -v $PWD/data:/pulsar/data --name pulsar-beat-standalone apachepulsar/pulsar:2.7.0 bin/pulsar standalone

Add following configuration to filebeat.yml

output.pulsar:
  url: "pulsar://pulsar-beat-standalone:6650"
  topic: my_topic
  name: test123

Start Filebeat

docker pull golang:1.17
docker run -it --network pulsar-beat --name filebeat golang:1.17 /bin/bash
git clone https://github.com/streamnative/pulsar-beat-output
cd pulsar-beat-output
go build -o filebeat filebeat/filebeat.go
chown -R root:root filebeat.yml test_module/modules.d/system.yml test_module/module/system
cp test_module/module/system/auth/test/test.log /var/log/messages.log
cp filebeat/filebeat filebeat.yml test_module
cd test_module
./filebeat modules enable system
./filebeat -c filebeat.yml -e

New open a window for consumer message

docker cp pulsar-client.py pulsar-beat-standalone:/pulsar
docker exec -it pulsar-beat-standalone /bin/bash
python pulsar-client.py

Now you can see the information collected from filebeat.
