An earlier post I made, ELK + Beats: Securing Communication with Logstash by using SSL, will have more information about this process for those interested. For the purpose of this guide, we will leave SSL out of it. NOTE: You can optionally configure SSL, which would require you to also un-comment out the “ ssl.certificate_authorities” line, however you will need to have a pre-configured certificate and key for this to work. Further down the file you will see a Logstash section – un-comment that out and add in the following: Make sure to replace the placeholder with your LS IP Reopen the configuration file and comment out the entire Elasticsearch section you just edited. Now that the templates are uploaded, you will now need to re-edit Filebeat’s configuration file to point it back at Logstash. By default, the files within this directory are all disabled, ending in “ yml.disabled.” When enabled, they become active “. You can also go to /etc/filebeat/modules.d and manually look through to see what modules are available and how they can be configured.

NOTE: A full list of modules within Filebeat can be found here. I will also use the NGINX module to monitor NGINX connections to my Kibana instance: filebeat setup -pipelines -modules system,nginx For my purposes, I know I will be utilizing the System module for grabbing authentication and system logs for my ELK nodes. You only need to do this ONCE from any node, as once it is uploaded Elasticsearch can handle the rest. Once saved, run the following command to upload the index templates for every module you want to use. Open it’s configuration file and add the following to the Elasticsearch section: nano /etc/filebeat/filebeat.yml Make sure to replace these placeholders with your ES IPs Go to the Filebeat installation directory: cd /etc/filebeat Now that we have Filebeat installed, we need to link it to your pre-existing Elasticsearch array and upload the templates for Elasticsearch to use.Įlevate to sudo if not done so already: sudo su

Update your repositories and install Filebeat: sudo apt-get update & sudo apt-get install filebeatĮnable Filebeat to run on system startup: systemctl enable filebeat Load default Index Templates Into Elasticsearch Grab dependencies if not already installed: sudo apt-get install apt-transport-httpsĪdd repository link to /etc/apt/: echo 'deb stable main' | sudo tee -a /etc/apt//elastic-6.x.list For the Filebeat-newbies, use the following commands to add the Elastic repo (if not already configured) and install Filebeat.ĭownload and install the Public Signing Key: wget -qO - | sudo apt-key add. If you already have Filebeat installed, you can skip this step. This guide will be based off Ubuntu, as my previous Filebeat post was CentOS.Current Filebeat Implementation OR Ability to Install Filebeat.As always, Multi-Node Stack is recommended for production.

This guide will explain how to do just that. You then need to configure Logstash to point to these templates when it recognizes a Filebeat module. To use the default ones for Filebeat, you first need to upload its module templates to Elasticsearch to be used. These templates can also be a neat way to apply Index Lifecycle Policies to groups of indices, which I hope to better understand and write a post on soon. For example, all indices that come from Logstash SHOULD have an index template attached to them known as “ logstash” unless one of your Logstash filters specifies otherwise. how do I use them?īased on my understanding, all index templates are normally applied in the background, which may be why some would have never dealt with them before. Changing a template will not affect pre-existing indices that use them. These templates are ONLY applied at index creation. Elasticsearch uses these templates to define settings and mappings that determine how fields should be analyzed and shown in Kibana. But what if you don’t want customization? Luckily, Filebeat has built in index templates you can use. This process utilized custom Logstash filters, which require you to manually add these in to your Logstash pipeline and filter all Filebeat logs that way. In one of my prior posts, Monitoring CentOS Endpoints with Filebeat + ELK, I described the process of installing and configuring the Beats Data Shipper Filebeat on CentOS boxes.
