Ship GitLab logs

GitLab is a DevOps platform that combines the ability to develop, secure, and operate software in a single application. This integration allows you to send logs from your GitLan platform to your Logz.io account.

Configuration

Before you begin, you’ll need:

GitLab locally installed
Filebeat installed
Port 5015 open

Download the Logz.io public certificate to your credentials server

For HTTPS shipping, download the Logz.io public certificate to your certificate authority folder.

sudo curl https://raw.githubusercontent.com/logzio/public-certificates/master/AAACertificateServices.crt --create-dirs -o /etc/pki/tls/certs/COMODORSADomainValidationSecureServerCA.crt

Add GitLab as an input

In the Filebeat configuration file (/etc/filebeat/filebeat.yml), add GitLab to the filebeat.inputs section.

GitLab has an advanced logging framework that ships a variety of different system logs. We recommend reading Log system from GitLab and modifying the Filebeat sample configuration according to your needs.

Replace <<LOG-SHIPPING-TOKEN>> with the token of the account you want to ship to.

Filebeat requires a file extension specified for the log input.

# ...

  - /var/log/gitlab/gitlab-rails/production_json.log

Preconfigured log types

Production logs in JSON format: gitlab-production-json
Production logs in plain text: gitlab-production
API logs: gitlab-api-json
Application logs: gitlab-application

The log type is used to apply the appropriate Logz.io preconfigured parsing pipeline so that your logs will be automatically parsed.

The default path to the logs differs, depending on how you’ve installed GitLab:

If installed from Omnibus packages, the default path is: /var/log/gitlab/...
If installed from source: /home/git/gitlab/log/...

Refer to GitLab Docs to learn more about the Log system.

Set Logz.io as the output

If Logz.io is not an output, add it now. Remove all other outputs.

Replace <<LISTENER-HOST>> with the host for your region. For example, listener.logz.io if your account is hosted on AWS US East, or listener-nl.logz.io if hosted on Azure West Europe. The required port depends whether HTTP or HTTPS is used: HTTP = 8070, HTTPS = 8071.

# ...
output.logstash:
  hosts: ["<<LISTENER-HOST>>:5015"]
  ssl:
    certificate_authorities: ['/etc/pki/tls/certs/COMODORSADomainValidationSecureServerCA.crt']

Start Filebeat

Start or restart Filebeat for the changes to take effect.

Check Logz.io for your logs

Give your logs some time to get from your system to ours, and then open Kibana.

If you still don’t see your logs, see Filebeat troubleshooting.
