Configure the outputedit
You configure APM Server to write to a specific output by setting options
in the Outputs section of the apm-server.yml
config file. Only a single
output may be defined.
The following topics describe how to configure each supported output. If you’ve secured the Elastic Stack, also read Secure for more about security-related configuration options.
Sourcemapsedit
Sourcemaps can be uploaded through all outputs but must eventually be stored in Elasticsearch.
When using outputs other than Elasticsearch, source_mapping.elasticsearch
must be set for source maps to be applied.
Be sure to update source_mapping.index_pattern
if sourcemaps are stored in the non-default location.
See source_mapping.elasticsearch
for more details.
fields
edit
Fields are optional tags that can be added to the documents that APM Server outputs.
They are defined at the top-level in your configuration file, and will apply to any configured output.
Fields can be scalar values, arrays, dictionaries, or any nested combination of these.
By default, the fields that you specify here will be grouped under a fields
sub-dictionary in the output document.
Example using the Elasticsearch output:
fields: {project: "myproject", instance-id: "574734885120952459"} #-------------------------- Elasticsearch output -------------------------- output.elasticsearch: hosts: ["localhost:9200"]
To store the custom fields as top-level fields, set the fields_under_root
option to true.
This is not recommended as when new fields are added to APM documents backward compatibility cannot be ensured.
