# Reference YAML
The Elastic Agent installation includes an `elastic-agent.reference.yml` file that describes all the settings available in a standalone configuration.
To ensure that you’re accessing the latest version, refer to the original [`elastic-agent.reference.yml` file](https://github.com/elastic/elastic-agent/blob/main/elastic-agent.reference.yml) in the `elastic/elastic-agent` repository. A copy is included here for your convenience.
Each section of the file and available settings are also described in [Structure of a config file](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/reference/fleet/structure-config-file).

#   #
#   # You can pass a `failon` parameter to the /liveness endpoint to determine what component state will result in a 500.
#   # For example: `curl 'localhost:6792/liveness?failon=degraded'` will return 500 if a component is in a degraded state.
#   # The possible values for `failon` are:
#   # `degraded`: return an error if a component is in a degraded state or failed state, or if the agent coordinator is unresponsive.
#   # `failed`: return an error if a unit is in a failed state, or if the agent coordinator is unresponsive.

# Logging

# There are four options for the log output: file, stderr, syslog, eventlog
# The file output is the default.

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

# Send all logging output to stderr. The default is false.
agent.logging.to_stderr: true

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

# Send all logging output to Windows Event Logs. The default is false.
#agent.logging.to_eventlog: false

# If enabled, Elastic-Agent 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. This setting is also passed
# to beats running under the agent. The default is true.
#agent.logging.metrics.enabled: true

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

# Logging to rotating files. Set logging.to_files to false to disable logging to
# files.
#agent.logging.to_files: true
#agent.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/elastic-agent

  # The name of the files where the logs are written to.
  #name: elastic-agent

  # Configure log file size limit. If limit is reached, log file will be
  # automatically rotated
  #rotateeverybytes: 20971520

  # 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

  # Enable log file rotation on time intervals in addition to size-based rotation.
  # Intervals must be at least 1s. Values of 1m, 1h, 24h, 7*24h, 30*24h, and 365*24h
  # are boundary-aligned with minutes, hours, days, weeks, months, and years as
  # reported by the local system clock. All other intervals are calculated from the
  # Unix epoch. Defaults to disabled.

  # file. Defaults to true.

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

#=============================== Events Logging ===============================
# Some outputs will log raw events on errors like indexing errors in the
# Elasticsearch output, to prevent logging raw events (that may contain
# sensitive information) together with other log messages, a different
# log file, only for log entries containing raw events, is used. It will
# use the same level, selectors and all other configurations from the
# default logger, but it will have it's own file configuration.
#
# Having a different log file for raw events also prevents event data
# from drowning out the regular log files.
#
# IMPORTANT: No matter the default logger output configuration, raw events
# will **always** be logged to a file configured by `agent.logging.event_data.files`.

# agent.logging.event_data:
# Logging to rotating files. Set agent.logging.to_files to false to disable logging to
# files.
