Install Logstash

Logstash is an open source data collection engine. It's designed to ingest data, usually logs. It can enhance or filter the data, and then forward it to a permanent back-end storage facility.

Make sure that all of the latest patches are installed.

sudo apt update
sudo apt dist-upgrade
sudo reboot

Configure Firewall:

sudo ufw allow ssh
sudo ufw allow 5044/tcp
sudo ufw enable

Install Install Java

Add the Elastic Search Key and Software:

wget -qO - | sudo apt-key add -
cat > /tmp/elastic-7.x.list << EOF
deb stable main
sudo mv /tmp/elastic-7.x.list /etc/apt/sources.list.d/
sudo apt update
sudo apt install -y logstash

If you are using ElasticSearch as the back-end storage, create the following configuration file:

cat > /tmp/beats.conf << EOF
input {
    beats {
        port => "5044"
output {
    elasticsearch {
        hosts => [""]
        manage_template => false
        index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
sudo cp /tmp/beats.conf /etc/logstash/conf.d/

Then enable and start the service:

sudo systemctl enable logstash
sudo service logstash start
