• These instructions are specific to our environment
• Messages, system, install and Filebeat logs will be sent
• If you have other services to log, contact CLS for details and a custom template
• Prerequisites: Terminal, vi or plain text editor, administrative account with root access

Installing Beats

1. Open Terminal and switch to root
   sudo su -
2. Download filebeat with this command:
   sudo curl -L -O curl -L -O

   curl -L -O https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-8.6.2-darwin-x86_64.tar.gz tar xzvf filebeat-8.6.2-darwin-x86_64.tar.gz
   

3. Rename the new directory and move it to /Applications/Utilities with this command:
   sudo mv filebeat-8.6.2-darwin-x86_64 /Applications/Utilities/filebeat/
4. Delete the compressed filebeat:
   sudo rm filebeat-8.6.2-darwin-x86_64.tar.gz
5. Using a web browser, download this certificate and copy to the /Applications/Utilities/filebeat folder:
   
   1. incommon_tls_chain.pem (from www.pki.vt.edu)

Configuring Beats

1. Download and copy this config file (filebeat.yml) into Applications/Utilities/filebeat, replacing the existing file
2. Open the filebeat.yml file you downloaded from /Applications/Utilities/filebeat/ with a plain text editor or vi
3. There are two changes you need to make to filebeat.yml
   
   1. This line appears twice and must be edited in both locations: index: "vt_logstash"
   2. Replace "vt_logstash" with the index name that was created in your consultation with CLS
   3. Do not change the indenting in the yml file
4. Save and close filebeat.yml
5. Set root as the owner for this file:
   
   1. sudo chown root /Applications/Utilities/filebeat/filebeat.yml

Testing Beats

1. In the Terminal in the /Applications/Utilities/filebeat directory
2. Check the configuration file is syntactically correct with this command:
   sudo /Applications/Utilities/filebeat/filebeat -c /Applications/Utilities/filebeat/filebeat.yml test config
3. Terminal should return "Config OK." Otherwise, correct errors and test again

Starting Beats

1. In the Terminal in the /Applications/Utilities/filebeat directory
2. Start the daemon:
   sudo ./filebeat -e -c filebeat.yml
