Step 3: Load the index template in Elasticsearch
editStep 3: Load the index template in Elasticsearch
editA connection to Elasticsearch is required to load the index template. If the output is not Elasticsearch, you must load the template manually.
In Elasticsearch, index templates are used to define settings and mappings that determine how fields should be analyzed.
The recommended index template file for Functionbeat is installed by the
Functionbeat packages. If you accept the default configuration in the
functionbeat.yml
config file, Functionbeat loads the template automatically
after successfully connecting to Elasticsearch. If the template already exists,
it’s not overwritten unless you configure Functionbeat to do so.
Configure template loading
editBy default, Functionbeat automatically loads the recommended template file,
fields.yml
, if the Elasticsearch output is enabled. If you want to use the
default index template, no additional configuration is required. Otherwise, you
can change the defaults in the functionbeat.yml
config file
to:
-
Load a different template
setup.template.name: "your_template_name" setup.template.fields: "path/to/fields.yml"
If the template already exists, it’s not overwritten unless you configure Functionbeat to do so.
-
Overwrite an existing template
setup.template.overwrite: true
-
Disable automatic template loading
setup.template.enabled: false
If you disable automatic template loading, you need to load the template manually.
-
Change the index name
If you’re sending events to a cluster that supports index lifecycle management, see Index lifecycle management (ILM) to learn how to change the index name.
Functionbeat uses time series indices, by default, when index lifecycle management is disabled or unsupported. The indices are named
functionbeat-7.6.2-yyyy.MM.dd
, whereyyyy.MM.dd
is the date when the events were indexed. To use a different name, you set theindex
option in the Elasticsearch output. The value that you specify should include the root name of the index plus version and date information. You also need to configure thesetup.template.name
andsetup.template.pattern
options to match the new name. For example:output.elasticsearch.index: "customname-%{[agent.version]}-%{+yyyy.MM.dd}" setup.template.name: "customname" setup.template.pattern: "customname-*"
If index lifecycle management is enabled (which is typically the default),
setup.template.name
andsetup.template.pattern
are ignored.
Remember to change the index name when you load dashboards via the Kibana UI.
See Elasticsearch index template for the full list of configuration options.
Load the template manually
editTo load the template manually, run the setup
command. A
connection to Elasticsearch is required. If another output is enabled, you need
to temporarily disable that output and enable Elasticsearch by using the -E
option.
The examples here assume that Logstash output is enabled.
You can omit the -E
flags if Elasticsearch output is already enabled.
If you are connecting to a secured Elasticsearch cluster, make sure you’ve configured credentials as described in Step 2: Configure Functionbeat.
If the host running Functionbeat does not have direct connectivity to Elasticsearch, see Load the template manually (alternate method).
To load the template, use the appropriate command for your system.
mac:
./functionbeat setup --index-management -E output.logstash.enabled=false -E 'output.elasticsearch.hosts=["localhost:9200"]'
brew:
functionbeat setup --index-management -E output.logstash.enabled=false -E 'output.elasticsearch.hosts=["localhost:9200"]'
linux:
./functionbeat setup --index-management -E output.logstash.enabled=false -E 'output.elasticsearch.hosts=["localhost:9200"]'
win:
Open a PowerShell prompt as an Administrator (right-click the PowerShell icon and select Run As Administrator).
From the PowerShell prompt, change to the directory where you installed Functionbeat, and run:
PS > .\functionbeat.exe setup --index-management -E output.logstash.enabled=false -E 'output.elasticsearch.hosts=["localhost:9200"]'
Force Kibana to look at newest documents
editIf you’ve already used Functionbeat to index data into Elasticsearch,
the index may contain old documents. After you load the index template,
you can delete the old documents from functionbeat-*
to force Kibana to look
at the newest documents.
Use this command:
mac:
curl -XDELETE 'http://localhost:9200/functionbeat-*'
linux:
curl -XDELETE 'http://localhost:9200/functionbeat-*'
win:
PS > Invoke-RestMethod -Method Delete "http://localhost:9200/functionbeat-*"
This command deletes all indices that match the pattern functionbeat-*
.
Before running this command, make sure you want to delete all indices that match
the pattern.
Load the template manually (alternate method)
editIf the host running Functionbeat does not have direct connectivity to Elasticsearch, you can export the index template to a file, move it to a machine that does have connectivity, and then install the template manually.
To export the index template, run:
mac:
./functionbeat export template > functionbeat.template.json
brew:
functionbeat export template > functionbeat.template.json
linux:
./functionbeat export template > functionbeat.template.json
win:
PS > .\functionbeat.exe export template --es.version 7.6.2 | Out-File -Encoding UTF8 functionbeat.template.json
To install the template, run:
mac:
curl -XPUT -H 'Content-Type: application/json' http://localhost:9200/_template/functionbeat-7.6.2 -d@functionbeat.template.json
linux:
curl -XPUT -H 'Content-Type: application/json' http://localhost:9200/_template/functionbeat-7.6.2 -d@functionbeat.template.json
win:
PS > Invoke-RestMethod -Method Put -ContentType "application/json" -InFile functionbeat.template.json -Uri http://localhost:9200/_template/functionbeat-7.6.2
