Guided configuration

Before you begin, you’ll need: Filebeat 7 or Filebeat 6, root access

Configure OSSEC for JSON alert output

In the OSSEC configuration file (/var/ossec/etc/ossec.conf), find the <global> tag. Add the <jsonout_output> property and set to yes.

<global>
  <jsonout_output>yes</jsonout_output>
</global>

Restart OSSEC.

sudo /var/ossec/bin/ossec-control restart
Download the Logz.io certificate

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

sudo wget https://raw.githubusercontent.com/logzio/public-certificates/master/COMODORSADomainValidationSecureServerCA.crt -P /etc/pki/tls/certs/
Add OSSEC as an input

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

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

# ...
filebeat.inputs:
- type: log

  paths:
  - /var/ossec/logs/alerts/alerts.json

  fields:
    logzio_codec: json

    # Your Logz.io account token. You can find your token at
    #  https://app.logz.io/#/dashboard/settings/manage-accounts
    token: <<SHIPPING-TOKEN>>
    type: ossec
  fields_under_root: true
  encoding: utf-8
  ignore_older: 3h

If you’re running Filebeat 7, paste this code block. Otherwise, you can leave it out.

# ... For Filebeat 7 only ...
filebeat.registry.path: /var/lib/filebeat
processors:
- rename:
    fields:
    - from: "agent"
      to: "filebeat_agent"
    ignore_missing: true
- rename:
    fields:
    - from: "log.file.path"
      to: "source"
    ignore_missing: true

If you’re running Filebeat 6, paste this code block.

# ... For Filebeat 6 only ...
registry_file: /var/lib/filebeat/registry
Add Logz.io as an output

If Logz.io is not an output, add it now.

Replace <<LISTENER-HOST>> with your region’s listener host (for example, listener.logz.io). For more information on finding your account’s region, see Account region.

# ...
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 log shipping troubleshooting.
