apm-server:
  # Defines the host and port the server is listening on
  host: "{{ apm_interface }}:{{ apm_port }}"

  # Maximum permitted size in bytes of an unzipped request accepted by the server to be processed.
  #max_unzipped_size: 52428800
  # Maximum permitted size in bytes of a request's header accepted by the server to be processed.
  #max_header_size: 1048576

  # Maximum permitted duration in seconds for reading an entire request.
  #read_timeout: 2s
  # Maximum permitted duration in seconds for writing a response.
  #write_timeout: 2s

  # Maximum duration in seconds before releasing resources when shutting down the server.
  #shutdown_timeout: 5s

  # Maximum number of requests permitted to be sent to the server concurrently.
  #concurrent_requests: 40

  # Authorization token to be checked. If a token is set here the agents must
  # send their token in the following format: Authorization: Bearer <secret-token>.
  # It is recommended to use an authorization token in combination with SSL enabled.
  secret_token: {{ apm_token }}
  #ssl.enabled: false

  # Please be aware that frontend support is an experimental feature at the moment!
  frontend:
    # To enable experimental frontend support set this to true.
    enabled: true

    # Rate limit per second and IP address for requests sent to the frontend endpoint.
    #rate_limit: 10

    # Comma separated list of permitted origins for frontend. User-agents will send
    # a origin header that will be validated against this list.
    # An origin is made of a protocol scheme, host and port, without the url path.
    # Allowed origins in this setting can have * to match anything (eg.: http://*.example.com)
    # If an item in the list is a single '*', everything will be allowed
    #allow_origins : ['*']

    # Regexp to be matched against a stacktrace frame's `file_name` and `abs_path` attributes.
    # If the regexp matches, the stacktrace frame is considered to be a library frame.
    #library_pattern: "node_modules|bower_components|~"

    # Regexp to be matched against a stacktrace frame's `file_name`.
    # If the regexp matches, the stacktrace frame is not used for calculating error groups.
    # The default pattern excludes stacktrace frames that have
    # - a filename starting with '/webpack'
    #exclude_from_grouping: "^/webpack"

    # If a source map has previously been uploaded, source mapping is automatically applied
    # to all error and transaction documents sent to the frontend endpoint.
    #source_mapping:

      # Source maps are are fetched from Elasticsearch and then kept in an in-memory cache for a certain time.
      # The `cache.expiration` determines how long a source map should be cached before fetching it again from Elasticsearch.
      # Note that values configured without a time unit will be interpreted as seconds.
      #cache:
        #expiration: 5m

      # Source maps are stored in the same index as transaction and error documents.
      # If the default index pattern at 'outputs.elasticsearch.index' is changed,
      # a matching index pattern needs to be specified here.
      #index_pattern: "apm-*"

#================================ General ======================================

# Internal queue configuration for buffering events to be published.
#queue:
  # Queue type by name (default 'mem')
  # The memory queue will present all available events (up to the outputs
  # bulk_max_size) to the output, the moment the output is ready to server
  # another batch of events.
  #mem:
    # Max number of events the queue can buffer.
    #events: 4096

    # Hints the minimum number of events stored in the queue,
    # before providing a batch of events to the outputs.
    # A value of 0 (the default) ensures events are immediately available
    # to be sent to the outputs.
    #flush.min_events: 2048

    # Maximum duration after which events are available to the outputs,
    # if the number of events stored in the queue is < min_flush_events.
    #flush.timeout: 1s

# Sets the maximum number of CPUs that can be executing simultaneously. The
# default is the number of logical CPUs available in the system.
#max_procs:

#================================ Outputs ======================================

# Configure what output to use when sending the data collected by the beat.

#----------------------------- Logstash output ---------------------------------

#================================= Paths ======================================

# The home path for the apm-server installation. This is the default base path
# for all other path settings and for miscellaneous files that come with the
# distribution (for example, the sample dashboards).
# If not set by a CLI flag or in the configuration file, the default for the
# home path is the location of the binary.
#path.home:

# The configuration path for the apm-server installation. This is the default
# base path for configuration files, including the main YAML configuration file
# and the Elasticsearch template file. If not set by a CLI flag or in the
# configuration file, the default for the configuration path is the home path.
#path.config: ${path.home}

# The data path for the apm-server installation. This is the default base path
# for all the files in which apm-server needs to store its data. If not set by a
# CLI flag or in the configuration file, the default for the data path is a data
# subdirectory inside the home path.
#path.data: ${path.home}/data

# The logs path for a apm-server installation. This is the default location for
# the Beat's log files. If not set by a CLI flag or in the configuration file,
# the default for the logs path is a logs subdirectory inside the home path.
#path.logs: ${path.home}/logs
