Step 3: Loading the Index Template in Elasticsearchedit

Before starting Packetbeat, you need to load the index template, which lets Elasticsearch know which fields should be analyzed in which way.

The recommended template file is installed by the Packetbeat packages. You can either configure Packetbeat to load the template automatically, or you can run a shell command to load the template:

Configuring Packetbeat to Load the Templateedit

To configure Packetbeat to load the template, you must enable the elasticsearch output. In the Packetbeat configuration file, uncomment the template part under elasticsearch output. By default the template is named packetbeat. Adjust the path to your template file.

    hosts: ["localhost:9200"]

    # A template is used to set the mapping in Elasticsearch
    # By default template loading is disabled and no template is loaded.
    # These settings can be adjusted to load your own template or overwrite existing ones

      # Template name. By default the template name is packetbeat.
      #name: "packetbeat"

      # Path to template file
      path: "packetbeat.template.json"

      # Overwrite existing template
      #overwrite: false

The template is loaded when you start Packetbeat. By default, if a template already exists in the index, it is not overwritten. To overwrite an existing template, set overwrite: true in the configuration file.

Running a Shell Command to Load the Templateedit

You can load the template by running the following command:

deb or rpm:

curl -XPUT 'http://localhost:9200/_template/packetbeat' -d@/etc/packetbeat/packetbeat.template.json


cd packetbeat-1.2.3-darwin
curl -XPUT 'http://localhost:9200/_template/packetbeat' -d@packetbeat.template.json


PS C:\Program Files\Packetbeat> Invoke-WebRequest -Method Put -InFile packetbeat.template.json -Uri http://localhost:9200/_template/packetbeat?pretty

where localhost:9200 is the IP and port where Elasticsearch is listening.

If you’ve already used Packetbeat to index data into Elasticsearch, the index may contain old documents. After you load the index template, you can delete the old documents from packetbeat-* to force Kibana to look at the newest documents. Use this command:

curl -XDELETE 'http://localhost:9200/packetbeat-*'
