Apache Storm is a free and open source distributed realtime computation system. This integration allows you to send logs from your Apache Storm server instances to your Layerlog account.

Step by step

Before you begin, you’ll need:

  • Filebeat 7 installed
  • Port 5015 open.
  • Root access
Download the Layerlog public certificate to your credentials server

For HTTPS shipping, download the Layerlog 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
Find Apache Storm log location

Run the following command to find your Apache Storm logs directory:

ps -o args= -C java | grep -Po -- '-Dstorm.log.dir=\K[^\s]+'
Add Apache Storm as an input

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

Replace <<LOG-SHIPPING-TOKEN>> with the token of the account you want to ship to. Replace <<LOGS_DIRECTORY>> with the path to your Apache Storm logs directory mentioned in the step above.

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

  paths:
    - <<LOGS_DIRECTORY>>/*.log
    - <<LOGS_DIRECTORY>>/workers-artifacts/*/*/*.log*

  exclude_files: ['.gz$']

  fields:
    logzio_codec: plain

    # You can manage your tokens at
    #  http://panel.layerlog.com/#/dashboard/settings/manage-tokens/log-shipping
    token: <<LOG-SHIPPING-TOKEN>>
    type: apache_storm
  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 and higher
filebeat.registry.path: /var/lib/filebeat
# The following processors are to ensure compatibility with version 7
processors:
- rename:
    fields:
    - from: "agent"
      to: "beat_agent"
    ignore_missing: true
- rename:
    fields:
    - from: "log.file.path"
      to: "source"
    ignore_missing: true
Set Layerlog as the output

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

Replace <<LISTENER-HOST>> with the host for your region. For example, listener.layerlog.com if your account is hosted on AWS US East, or listener-nl.layerlog.com 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 Layerlog for your logs

Give your logs some time to get from your system to ours, and then open Kibana. You can search for type:apache_storm to filter for your Apache Storm logs.
