Logstash is a tool used for ingesting, transforming and shipping data. It is part of the Elastic Stack which also includes Elasticsearch and Kibana. In this tutorial, we will show you how to install Logstash on OpenBSD.
Before getting started, ensure that the following prerequisites are met:
Logstash requires Java to be installed on your system. For OpenBSD, you can install the OpenJDK package using the following command:
$ doas pkg_add openjdk
Next, download the latest version of Logstash from the Elastic website using the following command:
$ wget https://artifacts.elastic.co/downloads/logstash/logstash-{version}.tar.gz
Replace {version} with the version number of Logstash you want to install.
Next, extract the downloaded tarball using the following command:
$ tar -xzf logstash-{version}.tar.gz
Logstash can be configured using a configuration file. A sample configuration file is present in the config directory of the extracted tarball. Make a copy of the logstash-sample.conf file using the following command:
$ cd logstash-{version}/config
$ cp logstash-sample.conf logstash.conf
You can now edit the logstash.conf file to configure Logstash according to your requirements.
You can start Logstash using the following command:
$ cd ..
$ bin/logstash -f config/logstash.conf
This command will start Logstash using the configuration file specified in the -f option.
You have now successfully installed Logstash on OpenBSD. You can now start using Logstash to ingest, transform and ship your data.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
