Filebeat System

Ship system logs to Logstash using Filebeat

Follow the steps below to send your observability data to Logit.io

Logs

Filebeat is an open source shipping agent that lets you ship logs from local files to one or more destinations, including Logstash.

Install Integration

Please click on the Install Integration button to configure your stack for this source.

Install Filebeat

To get started you will need to install filebeat. To do this you have two main options:

Choose the AMD / Intel file (x86_64) or
Choose the ARM file (arm64)

You can tell if you have a Linux PC with an AMD / Intel CPU (kernel) architecture by opening a terminal and running the uname -m command. If it displays x86_64 you have AMD / Intel architecture.

To successfully install filebeat you will need to have root access.

If you have an x86_64 system download and extract the contents of the file using the following commands:

curl -L -O https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-8.15.2-linux-x86_64.tar.gz
tar xzvf filebeat-8.15.2-linux-x86_64.tar.gz

If you have an arm64 system download and extract the contents of the file using the following commands:

curl -L -O https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-8.15.2-linux-arm64.tar.gz
tar xzvf filebeat-8.15.2-linux-arm64.tar.gz

Enable The System Module

There are several built in filebeat modules you can use. You will need to enable the system module.

Change directory to the location where filebeat was extracted and run the following commands:

sudo chown root filebeat.yml
sudo chown root modules.d/*.yml
sudo ./filebeat modules list
sudo ./filebeat modules enable system
sudo chown root module/system/syslog/*.yml
sudo chown root module/system/auth/*.yml

Navigate to the modules.d folder, copy the snippet below and replace the contents of the system.yml module file:

# Module: system
# Docs: https://www.elastic.co/guide/en/beats/filebeat/8.12/filebeat-module-system.html
 
- module: system
  syslog:
    enabled: true
 
    # Set custom paths for the log files. If left empty,
    # Filebeat will choose the paths depending on your OS.
    #var.paths: ["/path/to/log/syslog*"]
 
  # Authorization logs
  auth:
    enabled: true
 
    # Set custom paths for the log files. If left empty,
    # Filebeat will choose the paths depending on your OS.
    #var.paths: ["/path/to/log/auth.log*"]

Update your configuration file

The configuration file below is pre-configured to send data to your Logit.io Stack via Logstash.

Copy the configuration file below (making the above changes as necessary) and overwrite the contents of filebeat.yml (this file can be found in the location where you installed Filebeat in the previous step).

Filebeat modules offer the quickest way to begin working with standard log formats. If you opt to configure Filebeat manually rather than utilizing modules, you'll do so by listing inputs in the filebeat.inputs section of filebeat.yml. These inputs detail how Filebeat discovers and handles input data.

  ###################### Logit.io Filebeat Configuration ########################
  # ============================== Filebeat inputs ==============================

Validate Configuration

sudo ./@beatname test config -c @beatname.yml --strict.perms=false

You'll be running as root, so you need to change ownership of the configuration file and any configurations enabled in the modules.d directory, or run with --strict.perms=false as shown above. Read more about how to change ownership.

If the yml file is invalid, @beatname will print a description of the error. For example, if the output.logstash section was missing, @beatname would print no outputs are defined, please define one under the output section

Start filebeat

To start Filebeat, run:

sudo chown root filebeat.yml 
sudo chown root modules.d/system.yml 
sudo ./filebeat -e

You'll be running filebeat as root, so you need to change ownership of the configuration file and any configurations enabled in the modules.d directory, or run filebeat with --strict.perms=false as shown above.

Read more about how to change ownership (opens in a new tab).
