+# This file configures the New Relic Agent.  New Relic monitors

+# For more information, visit www.newrelic.com.

+
+
+# Here are the settings that are common to all environments
+common: &default_settings
+  # ============================== LICENSE KEY ===============================
+
+  # You must specify the license key associated with your New Relic
+  # account.  This key binds your Agent's data to your account in the
+  # New Relic service.
+  license_key: 'replaced by env var'
+
+  # Agent Enabled (Ruby/Rails Only)
+  # Use this setting to force the agent to run or not run.
+  # Default is 'auto' which means the agent will install and run only
+  # if a valid dispatcher such as Mongrel is running.  This prevents
+  # it from running with Rake or the console.  Set to false to
+  # completely turn the agent off regardless of the other settings.
+  # Valid values are true, false and auto.
+  #
+  # agent_enabled: auto
+
+  # Application Name Set this to be the name of your application as
+  # you'd like it show up in New Relic. The service will then auto-map
+  # instances of your application into an "application" on your
+  # dashboard page. If you want to map this instance into multiple
+  # apps, like "AJAX Requests" and "All UI" then specify a semicolon
+  # separated list of up to three distinct names, or a yaml list.
+  # Defaults to the capitalized RAILS_ENV or RACK_ENV (i.e.,
+  # Production, Staging, etc)
+  #
+  # Example:
+  #
+  #   app_name:
+  #       - Ajax Service
+  #       - All Services
+  #
+  app_name: Steno
+
+  # When "true", the agent collects performance data about your
+  # application and reports this data to the New Relic service at
+  # newrelic.com. This global switch is normally overridden for each
+  # environment below. (formerly called 'enabled')
+  monitor_mode: true
+
+  # Developer mode should be off in every environment but
+  # development as it has very high overhead in memory.
+  developer_mode: false
+
+  # The newrelic agent generates its own log file to keep its logging
+  # information separate from that of your application. Specify its
+  # log level here.
+  log_level: info
+
+  # Optionally set the path to the log file This is expanded from the
+  # root directory (may be relative or absolute, e.g. 'log/' or
+  # '/var/log/') The agent will attempt to create this directory if it
+  # does not exist.
+  # log_file_path: 'log'
+
+  # Optionally set the name of the log file, defaults to 'newrelic_agent.log'
+  # log_file_name: 'newrelic_agent.log'
+
+  # The newrelic agent communicates with the service via https by default.  This
+  # prevents eavesdropping on the performance metrics transmitted by the agent.
+  # The encryption required by SSL introduces a nominal amount of CPU overhead,
+  # which is performed asynchronously in a background thread.  If you'd prefer
+  # to send your metrics over http uncomment the following line.
+  # ssl: false
+
+  #============================== Browser Monitoring ===============================
+  # New Relic Real User Monitoring gives you insight into the performance real users are
+  # experiencing with your website. This is accomplished by measuring the time it takes for
+  # your users' browsers to download and render your web pages by injecting a small amount
+  # of JavaScript code into the header and footer of each page.
+  browser_monitoring:
+      # By default the agent automatically injects the monitoring JavaScript
+      # into web pages. Set this attribute to false to turn off this behavior.
+      auto_instrument: false
+
+  # Proxy settings for connecting to the New Relic server.
+  #
+  # If a proxy is used, the host setting is required.  Other settings
+  # are optional. Default port is 8080.
+  #
+  # proxy_host: hostname
+  # proxy_port: 8080
+  # proxy_user:
+  # proxy_pass:
+
+  # The agent can optionally log all data it sends to New Relic servers to a
+  # separate log file for human inspection and auditing purposes. To enable this
+  # feature, change 'enabled' below to true.
+  # See: https://newrelic.com/docs/ruby/audit-log
+  audit_log:
+    enabled: false
+
+  # Tells transaction tracer and error collector (when enabled)
+  # whether or not to capture HTTP params.  When true, frameworks can
+  # exclude HTTP parameters from being captured.
+  # Rails: the RoR filter_parameter_logging excludes parameters
+  # Java: create a config setting called "ignored_params" and set it to
+  #     a comma separated list of HTTP parameter names.
+  #     ex: ignored_params: credit_card, ssn, password
+  capture_params: false
+
+  # Transaction tracer captures deep information about slow
+  # transactions and sends this to the New Relic service once a
+  # minute. Included in the transaction is the exact call sequence of
+  # the transactions including any SQL statements issued.
+  transaction_tracer:
+
+    # Transaction tracer is enabled by default. Set this to false to
+    # turn it off. This feature is only available at the Professional
+    # and above product levels.
+    enabled: true
+
+    # Threshold in seconds for when to collect a transaction
+    # trace. When the response time of a controller action exceeds
+    # this threshold, a transaction trace will be recorded and sent to
+    # New Relic. Valid values are any float value, or (default) "apdex_f",
+    # which will use the threshold for an dissatisfying Apdex
+    # controller action - four times the Apdex T value.
+    transaction_threshold: apdex_f
+
+    # When transaction tracer is on, SQL statements can optionally be
+    # recorded. The recorder has three modes, "off" which sends no
+    # SQL, "raw" which sends the SQL statement in its original form,
+    # and "obfuscated", which strips out numeric and string literals.
+    record_sql: obfuscated
+
+    # Threshold in seconds for when to collect stack trace for a SQL
+    # call. In other words, when SQL statements exceed this threshold,
+    # then capture and send to New Relic the current stack trace. This is
+    # helpful for pinpointing where long SQL calls originate from.
+    stack_trace_threshold: 0.500
+
+    # Determines whether the agent will capture query plans for slow
+    # SQL queries.  Only supported in mysql and postgres.  Should be
+    # set to false when using other adapters.

+
+    # Threshold for query execution time below which query plans will
+    # not be captured.  Relevant only when `explain_enabled` is true.
+    # explain_threshold: 0.5
+
+  # Error collector captures information about uncaught exceptions and
+  # sends them to New Relic for viewing
+  error_collector:
+
+    # Error collector is enabled by default. Set this to false to turn
+    # it off. This feature is only available at the Professional and above
+    # product levels.
+    enabled: true
+
+    # Rails Only - tells error collector whether or not to capture a
+    # source snippet around the place of the error when errors are View
+    # related.
+    capture_source: true
+
+    # To stop specific errors from reporting to New Relic, set this property
+    # to comma-separated values.  Default is to ignore routing errors,
+    # which are how 404's get triggered.
+    ignore_errors: "ActionController::RoutingError,Sinatra::NotFound"
+
+  # If you're interested in capturing memcache keys as though they
+  # were SQL uncomment this flag. Note that this does increase
+  # overhead slightly on every memcached call, and can have security
+  # implications if your memcached keys are sensitive
+  # capture_memcache_keys: true
+
+# Application Environments
+# ------------------------------------------
+# Environment-specific settings are in this section.
+# For Rails applications, RAILS_ENV is used to determine the environment.
+# For Java applications, pass -Dnewrelic.environment <environment> to set
+# the environment.
+
+# NOTE if your application has other named environments, you should
+# provide newrelic configuration settings for these environments here.
+
+development:
+  <<: *default_settings
+  # Turn off communication to New Relic service in development mode (also
+  # 'enabled').
+  # NOTE: for initial evaluation purposes, you may want to temporarily
+  # turn the agent on in development mode.
+  monitor_mode: false
+
+  # Rails Only - when running in Developer Mode, the New Relic Agent will
+  # present performance information on the last 100 transactions you have
+  # executed since starting the mongrel.
+  # NOTE: There is substantial overhead when running in developer mode.
+  # Do not use for production or load testing.
+  developer_mode: true
+
+  # Enable textmate links
+  # textmate: true
+
+test:
+  <<: *default_settings
+  # It almost never makes sense to turn on the agent when running
+  # unit, functional or integration tests or the like.
+  monitor_mode: false
+
+# Turn on the agent in production for 24x7 monitoring. NewRelic
+# testing shows an average performance impact of < 5 ms per
+# transaction, you can leave this on all the time without
+# incurring any user-visible performance degradation.
+production:
+  <<: *default_settings
+  monitor_mode: true
+
+# Many applications have a staging environment which behaves
+# identically to production. Support for that environment is provided
+# here.  By default, the staging environment has the agent turned on.
+staging:
+  <<: *default_settings
+  monitor_mode: true
+  # app_name: My Application (Staging)
