#================================= 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


#================================ Logging ======================================
#
# There are three options for the log output: syslog, file, stderr.
# Under Windows systems, the log files are per default sent to the file output,
# under all other system per default to syslog.

# Sets log level. The default log level is info.
# Available log levels are: error, warning, info, debug
#logging.level: info

# Enable debug output for selected components. To enable all selectors use ["*"]
# Other available selectors are "beat", "publish", "service"
# Multiple selectors can be chained.
#logging.selectors: [ ]

# Send all logging output to syslog. The default is false.
#logging.to_syslog: true

# If enabled, apm-server periodically logs its internal metrics that have changed
# in the last period. For each metric that changed, the delta from the value at
# the beginning of the period is logged. Also, the total values for
# all non-zero internal metrics are logged on shutdown. The default is true.
logging.metrics.enabled: false

# The period after which to log the internal metrics. The default is 30s.
#logging.metrics.period: 30s

# Logging to rotating files. Set logging.to_files to false to disable logging to
# files.
#logging.to_files: true
#logging.files:
  # Configure the path where the logs are written. The default is the logs directory
  # under the home path (the binary location).
  #path: /var/log/apm-server

  # The name of the files where the logs are written to.
  #name: apm-server

  # Configure log file size limit. If limit is reached, log file will be
  # automatically rotated
  #rotateeverybytes: 10485760 # = 10MB

  # Number of rotated log files to keep. Oldest files will be deleted first.
  #keepfiles: 7

  # The permissions mask to apply when rotating log files. The default value is 0600.
  # Must be a valid Unix-style file permissions mask expressed in octal notation.
  #permissions: 0600

# Set to true to log messages in json format.
#logging.json: false


#================================ HTTP Endpoint ======================================
#
# Each beat can expose internal metrics through a HTTP endpoint. For security
# reasons the endpoint is disabled by default. This feature is currently experimental.
# Stats can be access through http://localhost:5066/stats . For pretty JSON output
# append ?pretty to the URL.

# Defines if the HTTP endpoint is enabled.
#http.enabled: false

# The HTTP endpoint will bind to this hostname or IP address. It is recommended to use only localhost.
#http.host: localhost

# Port on which the HTTP endpoint will bind. Default is 5066.
#http.port: 5066

#============================== Xpack Monitoring ===============================
# APM server can export internal metrics to a central Elasticsearch monitoring
# cluster.  This requires xpack monitoring to be enabled in Elasticsearch.  The
# reporting is disabled by default.

# Set to true to enable the monitoring reporter.
#xpack.monitoring.enabled: false

# Uncomment to send the metrics to Elasticsearch. Most settings from the
# Elasticsearch output are accepted here as well. Any setting that is not set is
# automatically inherited from the Elasticsearch output configuration, so if you
# have the Elasticsearch output configured, you can simply uncomment the
# following line.
#xpack.monitoring.elasticsearch:
#  username: "apm_system"
#  password: ""
