Filebeat configuration
Before you begin, you’ll need:
- Filebeat 7 or Filebeat 6
- Root access
- Port 5015 open
Configure OSSEC to output JSON alerts
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 public certificate to your Filebeat 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 OSSEC as an input
In the Filebeat configuration file (/etc/filebeat/filebeat.yml), add OSSEC to the filebeat.inputs section.
Replace <<LOG-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: <<LOG-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
The above assumes the following defaults:
- Log locations (JSON format) -
/var/ossec/logs/alerts/alerts.json
- Log locations (plain text format) -
/var/ossec/logs/alerts/alerts.log
Set Logz.io as the output
If Logz.io is not an output, add it now. Remove all other outputs.
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.
You can search for type:ossec
to filter for your logs. Your logs should be already parsed thanks to the Logz.io preconfigured parsing pipeline.
If you still don’t see your logs, see log shipping troubleshooting.
