Shipping Jenkins logs with Filebeat
Before you begin, you’ll need:
- Filebeat 7 or Filebeat 6
- Root access
- Port 5015 open
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 Jenkins as an input
In the Filebeat configuration file (/etc/filebeat/filebeat.yml), add Jenkins to the filebeat.inputs section.
Replace <<LOG-SHIPPING-TOKEN>>
with the token of the account you want to ship to.
Replace <
# ...
filebeat.inputs:
- type: log
paths:
- /var/log/jenkins/jenkins.log
- /var/<<JENKINS-HOME>>/jobs/*/builds/lastFailedBuild/log
fields:
logzio_codec: plain
# You can manage your tokens at
# https://app.logz.io/#/dashboard/settings/manage-tokens/log-shipping

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 configuration assumes the following defaults:
- Log location -
/var/log/jenkins/jenkins.log
- Log type -
jenkins
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.
# ...
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:jenkins
to filter for your Jenkins 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.
