In Elasticsearch, index templates are used to define settings and mappings that determine how fields should be analyzed.
The recommended index template file for APM Server is installed by the
APM Server packages. If you accept the default configuration in the
apm-server.yml config file, APM Server loads the template automatically
after successfully connecting to Elasticsearch. If the template already exists,
it’s not overwritten unless you configure APM Server to do so.
You can disable automatic template loading, or load your own template, by configuring template loading options in the APM Server configuration file.
You can also set options to change the name of the index and index template.
For more information, see:
By default, APM Server automatically loads the recommended template file,
fields.yml, if the Elasticsearch output is enabled. You can change the
defaults in the
apm-server.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 APM Server to do so.
Overwrite an existing template
Disable automatic template loading
If you disable automatic template loading, you need to load the template manually.
Change the index name
By default, APM Server writes events to indices named
yyyy.MM.ddis the date when the events were indexed. To use a different name, you set the
indexoption 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 the
setup.template.patternoptions to match the new name. For example:
If you plan to set up the Kibana dashboards, also set this option to overwrite the index name defined in the dashboards and index pattern.
See Load the Elasticsearch index template for the full list of configuration options.
To load the template manually, run the
setup command. A
connection to Elasticsearch is required.
If you are connecting to a secured Elasticsearch cluster, make sure you’ve configured credentials as described in Configuration file.
If the host running APM Server 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.
Open a PowerShell prompt as an Administrator (right-click the PowerShell icon and select Run As Administrator). If you are running Windows XP, you may need to download and install PowerShell.
From the PowerShell prompt, change to the directory where you installed APM Server, and run:
PS > .\apm-server setup --template -E 'output.elasticsearch.hosts=["localhost:9200"]'
If you’ve already used APM Server to index data into Elasticsearch,
the index may contain old documents. After you load the index template,
you can delete the old documents from
apm-server-* to force Kibana to look
at the newest documents. Use this command:
deb, rpm, and mac:
curl -XDELETE 'http://localhost:9200/apm-server-*'
PS > Invoke-RestMethod -Method Delete "http://localhost:9200/apm-server-*"
This command deletes all indices that match the pattern
Before running this command, make sure you want to delete all indices that match
If the host running APM Server 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.
Export the index template:
PS> .\apm-server.exe export template --es.version 6.3.0 | Out-File -Encoding UTF8 apm-server.template.json
Install the template:
deb, rpm, and mac:
curl -XPUT -H 'Content-Type: application/json' http://localhost:9200/_template/apm-server-6.3.0 -email@example.com
PS > Invoke-RestMethod -Method Put -ContentType "application/json" -InFile apm-server.template.json -Uri http://localhost:9200/_template/apm-server-6.3.0
