![]() Something else I had to take into consideration when setting up Filebeat was data security. If you want to output to multiple places (for example directly to Elasticsearch, but also to Logstash) you need to add a second configuration file, effectively calling another instance of the Beat. The configuration file can only output to one place.YAML (by design) is very specific about formatting, so if you’re getting errors consider using a YAML tester website to ensure your syntax is correct. If you haven’t worked with YAML before, you should go and read up on what you need to do to ensure that your configuration file is correct. All of the configuration files are in YAML format. ![]() Get the Beat working initially by calling it directly, and once everything is working you can start it as a daemon. Beats can be run directly as an executable, or as a daemon.You should start the Beat with the -e flag while getting your configuration correct so that you can see what the Beat is doing. Beats doesn’t output errors to the console by default.I’ve listed them below in the hope that you may save some time if you’re trying this yourself: Using the starter template and documentation I was able to get Filebeat to upload data to Elasticsearch, however, there were a few gotchas that I had to learn about along the way. The configuration file is a YAML file that is interpreted by Filebeat on starting the application. This was done through the configuration file. The next step was to configure Filebeat to pick up my log file and pass it through to Elasticsearch. Filebeat can be installed using a binary or by using a package manager such as apt or yum in Linux from the Elastic OSS Download Page. As I was creating a log file the right choice was Filebeat, which is designed to check a log file for new lines and upload to Elasticsearch. I first decided which of the Beats I should use. To get a feel for Elastic Beats, I wanted to see if I could use the same ISS data API to upload to Elasticsearch, and how the process compared to Logstash. In my last blog post, I created a log of the International Space Station (ISS) coordinates which I had manipulated using Logstash and added to Elasticsearch. Read: OpenSearch and Elasticsearch Architecture How to Install Elastic Beats and Configure It to Upload My ISS Data Using the open source versions allow for maximum flexibility when deploying long term. Elastic also offers a developer kit called Libbeat to help build your own Beat if you have the technical knowledge.Įlastic Beats are offered under an Open Source Apache 2.0 Licence (OSS), which I will be using with Instaclustr’s Managed Elasticsearch to ensure compatibility with our open source offering. This means they can be installed wherever they are needed so that data and metrics can be sent to Elasticsearch instead of being stuck in the logs on the machine.Įlastic Beats are written in the Go programming language and there are many open source Beats available in the Elasticsearch community that are outside of the ones maintained by Elastic. The benefit of the Beats doing very little processing and data manipulation is that it makes them extremely light on system resources. ![]() Some potential use cases for Elastic Beats. This is about all it does-there is very little configuration and very little data manipulation you can do in a Beat-it just sends the data somewhere else for processing. ![]() contents of a log file, metrics on a system, network activity, etc.) to Elasticsearch or Logstash in real time. So what is a data shipper I hear you say? A data shipper is exactly what it sounds like: The shipper (a Beat) ships data (e.g. There are many different Beats out there, as they are often created for specific use cases by the Elasticsearch community, but the ones offered and maintained by Elastic are Metricbeat, Winlogonbeat, Filebeat, Packetbeat, Auditbeat, and Heartbeat. What Is Elastic Beats (or More Correctly, What ARE Elastic Beats)?Įlastic Beats are a series of different data shippers that are set up and configured to send data from a server or computer into Elasticsearch-either directly, or via Logstash. In this blog, I’ll take a deeper look at Beats to understand how it works, what you might use it for, and how it compares with Logstash. After my last blog post about Logstash, Elasticsearch, and Kibana, I wanted to investigate something else I kept coming across during my Logstash research: Elastic Beats.īeats initially appeared to me to be a way to send data to Elasticsearch, the same as Logstash, leading me to wonder how Beats is different and where it fits in the ELK stack.
