Apache Logstash Configuration

To get started first follow the steps below:

• Install
• Root access
• Verify the required port is open

Older versions can be found here 7, 6, 5

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

deb/rpm

sudo filebeat modules list
sudo filebeat modules enable apache

macOS

cd <EXTRACTED_ARCHIVE>
./filebeat modules list
./filebeat modules enable apache

Windows

cd <EXTRACTED_ARCHIVE>
.\filebeat.exe modules list
.\filebeat.exe modules enable apache

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

Copy the configuration file below and overwrite the contents of filebeat.yml.

# ============================== Filebeat modules ==============================
filebeat.config.modules:
  path: ${path.config}/modules.d/*.yml
  reload.enabled: false
  #reload.period: 10s

# ================================== Outputs ===================================
# ------------------------------ Logstash Output -------------------------------
output.logstash:
    hosts: ["your-logstash-host:your-ssl-port"]
    loadbalance: true
    ssl.enabled: true

# ================================= Processors =================================
processors:
  - add_host_metadata:
      when.not.contains.tags: forwarded
  - add_cloud_metadata: ~
  - add_docker_metadata: ~
  - add_kubernetes_metadata: ~

If you’re running Filebeat 7 add this code block to the end. Otherwise, you can leave it out.

# ... For Filebeat 7 only ...
filebeat.registry.path: /var/lib/filebeat

If you’re running Filebeat 6 add this code block to the end. Otherwise, you can leave it out.

# ... For Filebeat 6 only ...
registry_file: /var/lib/filebeat/registry

Validate your YAML

It’s a good idea to run the configuration file through a YAML validator to rule out indentation errors, clean up extra characters, and check if your YAML file is valid. Yamllint.com is a great choice.

If you have issues starting in the next step, you can use these commands below to troubleshoot.

Let's check the configuration file is syntactically correct by running directly inside the terminal. If the file is invalid, will print an error loading config file error message with details on how to correct the problem.

deb/rpm

sudo  -e -c /etc//.yml

macOS

cd <EXTRACTED_ARCHIVE>
sudo ./ -e -c .yml

Windows

cd <EXTRACTED_ARCHIVE>
.\.exe -e -c .yml

Start or restart to apply the configuration changes.

Additional module configuration can be done using the per module config files located in the modules.d folder, most commonly this would be to read logs from a non-default location

deb/rpm /etc/filebeat/modules.d/apache.yml
mac/win <EXTRACTED_ARCHIVE>/modules.d/apache.yml

- module: apache
# Access logs
access:
  enabled: true

  # Set custom paths for the log files. If left empty,
  # Filebeat will choose the paths depending on your OS.
  var.paths: ["/custom/path/to/logs"]

# Error logs
error:
  enabled: true

  # Set custom paths for the log files. If left empty,
  # Filebeat will choose the paths depending on your OS.
  var.paths: ["/custom/path/to/logs"]

Now you should view your data:

Launch Dashboard

If you don't see logs take a look at How to diagnose no data in Stack below for how to diagnose common issues.

If you don't see data appearing in your Stack after following the steps, visit the Help Centre guide for steps to diagnose no data appearing in your Stack or Chat to support now.

The Apache module comes with predefined Kibana dashboards. To view your dashboards for any of your Logit.io stacks, launch Kibana and choose Dashboards.

Apache (also known as Apache HTTP Server) is a popular open-source web server that manages incoming HTTP requests. The first edition of Apache was launched over twenty years ago in 1995 & has grown to power over 40% of websites globally. Just one of the reasons for its widespread adoption is due to its highly flexible and powerful features.

Apache produces access & error logs and as a server that manages HTTP requests, the tool generates a high amount of log data when used to monitor high traffic websites. This can be difficult to efficiently analyse without an Apache log viewer.

The error log is characterised as the most important log data you’ll want to analyse as part of your audits. It contains a wealth of information beyond just errors & can be used for comprehensive diagnostic reporting. Access logs keep track of all access requests that have been sent to your web server and include data such as IP addresses, URLs & response times.

Logit.io provides a complete solution for fast Apache log viewing & analysis. Our platform’s built-in Apache log analyser saves on the need to configure numerous tools for the ingestion of Apache server logs as our hosted ELK Stack takes care of transforming, parsing, alerting, visualising & reporting in one centralised platform.
