    List of metrics to be logged. Available values are described under Metrics.

    • name

      string required Must be one of: kong_latency, latency, request_count, request_per_user, request_size, response_size, status_count, status_count_per_user, unique_users, upstream_latency, status_count_per_workspace, status_count_per_user_per_route, shdict_usage, cache_datastore_hits_total, cache_datastore_misses_total

    • stat_type

      string required Must be one of: counter, gauge, histogram, meter, set, timer

    • sample_rate

      number

    • consumer_identifier

      string Must be one of: consumer_id, custom_id, username

    • service_identifier

      string Must be one of: service_id, service_name, service_host, service_name_or_host

    • workspace_identifier

      string Must be one of: workspace_id, workspace_name

  • allow_status_codes

    array of type string

    List of status code ranges that are allowed to be logged in metrics.

  • udp_packet_size

    number default: 0 between: 0 65507

    Combine UDP packet up to the size configured. If zero (0), don’t combine the UDP packet. Must be a number between 0 and 65507 (inclusive).

  • use_tcp

    boolean default: false

    Use TCP instead of UDP.

  • hostname_in_prefix

    boolean default: false

    Include the hostname in the prefix for each metric name.

  • consumer_identifier_default

    string required default: custom_id Must be one of: consumer_id, custom_id, username

    The default consumer identifier of metrics. This takes effect when a metric’s consumer identifier is omitted. Allowed values are custom_id, consumer_id, username.

  • service_identifier_default

    string required default: service_name_or_host Must be one of: service_id, service_name, service_host, service_name_or_host

    The default service identifier of metrics. This takes effect when a metric’s service identifier is omitted. Allowed values are service_name_or_host, service_id, service_name, service_host.

  • workspace_identifier_default

    string required default: workspace_id Must be one of: workspace_id, workspace_name

    The default workspace identifier of metrics. This will take effect when a metric’s workspace identifier is omitted. Allowed values are workspace_id, workspace_name.

  • retry_count

    integer

    Number of times to retry when sending data to the upstream server.

  • queue_size

    integer

    Maximum number of log entries to be sent on each message to the upstream server.

  • flush_timeout

    number

    Optional time in seconds. If queue_size > 1, this is the max idle time before sending a log with less than queue_size records.

  • tag_style

    string Must be one of: dogstatsd, influxdb, librato, signalfx

    The tag style configurations to send metrics with tags. Defaults to nil, which doesn’t add any tags to the metrics. Allowed values are dogstatsd, influxdb, librato, and signalfx.

  • queue

    record required
    • max_batch_size

      number default: 1 between: 1 1000000

      Maximum number of entries to be processed together as a batch.

    • max_coalescing_delay

      number default: 1 between: 0 3600

      Maximum number of seconds (as a fraction) that can elapse after the first entry was queued before the queue starts processing entries. This parameter has no effect when batch_max_size is one because queued entries will be sent immediately in that case.

    • max_entries

      number default: 10000 between: 1 1000000

      Maximum number of entries that can be waiting on the queue. Once this number of requests is reached, the oldest entry is deleted from the queue before a new one is added.

    • max_bytes

      number

      Maximum number of bytes that can be waiting on a queue. Once this many bytes are present on a queue, old entries up to the size of a new entry to be enqueued are deleted from the queue.

    • max_retry_time

      number default: 60

      Time (in seconds) before the queue gives up trying to send a batch of entries. Once this time is exceeded for a batch, it is deleted from the queue without being sent. If his parameter is set to -1, no retries will be made for a failed batch.

    • initial_retry_delay

      number default: 0.01

      Maximum time (in seconds) between retries sending a batch of entries. The interval between retries follows an exponential back-off algorithm capped at this number of seconds.

    • max_retry_delay

      number default: 60
