wavefront

Wavefront Output Plugin

This plugin writes to a Wavefront instance or a Wavefront Proxy instance over HTTP or HTTPS.

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Secret-store support

This plugin supports secrets from secret-stores for the token option. See the secret-store documentation for more details on how to use them.

Configuration

[[outputs.wavefront]]
  ## Url for Wavefront API or Wavefront proxy instance.
  ## Direct Ingestion via Wavefront API requires authentication. See below.
  url = "https://metrics.wavefront.com"

  ## Maximum number of metrics to send per HTTP request. This value should be higher than the `metric_batch_size`. Default is 10,000. Values higher than 40,000 are not recommended.
  # http_maximum_batch_size = 10000

  ## prefix for metrics keys
  # prefix = "my.specific.prefix."

  ## whether to use "value" for name of simple fields. default is false
  # simple_fields = false

  ## character to use between metric and field name.  default is . (dot)
  # metric_separator = "."

  ## Convert metric name paths to use metricSeparator character
  ## When true will convert all _ (underscore) characters in final metric name. default is true
  # convert_paths = true

  ## Use Strict rules to sanitize metric and tag names from invalid characters
  ## When enabled forward slash (/) and comma (,) will be accepted
  # use_strict = false

  ## Use Regex to sanitize metric and tag names from invalid characters
  ## Regex is more thorough, but significantly slower. default is false
  # use_regex = false

  ## point tags to use as the source name for Wavefront (if none found, host will be used)
  # source_override = ["hostname", "address", "agent_host", "node_host"]

  ## whether to convert boolean values to numeric values, with false -> 0.0 and true -> 1.0. default is true
  # convert_bool = true

  ## Truncate metric tags to a total of 254 characters for the tag name value. Wavefront will reject any
  ## data point exceeding this limit if not truncated. Defaults to 'false' to provide backwards compatibility.
  # truncate_tags = false

  ## Flush the internal buffers after each batch. This effectively bypasses the background sending of metrics
  ## normally done by the Wavefront SDK. This can be used if you are experiencing buffer overruns. The sending
  ## of metrics will block for a longer time, but this will be handled gracefully by the internal buffering in
  ## Telegraf.
  # immediate_flush = true

  ## Send internal metrics (starting with `~sdk.go`) for valid, invalid, and dropped metrics. default is true.
  # send_internal_metrics = true

  ## Optional TLS Config
  ## Set to true/false to enforce TLS being enabled/disabled. If not set,
  ## enable TLS only if any of the other options are specified.
  # tls_enable =
  ## Trusted root certificates for server
  # tls_ca = "/path/to/cafile"
  ## Used for TLS client certificate authentication
  # tls_cert = "/path/to/certfile"
  ## Used for TLS client certificate authentication
  # tls_key = "/path/to/keyfile"
  ## Send the specified TLS server name via SNI
  # tls_server_name = "kubernetes.example.com"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

  ## HTTP Timeout
  # timeout="10s"

  ## MaxIdleConns controls the maximum number of idle (keep-alive)
  ## connections across all hosts. Zero means no limit.
  # max_idle_conn = 0

  ## MaxIdleConnsPerHost, if non-zero, controls the maximum idle
  ## (keep-alive) connections to keep per-host. If zero,
  ## DefaultMaxIdleConnsPerHost is used(2).
  # max_idle_conn_per_host = 2

  ## Idle (keep-alive) connection timeout.
  ## Maximum amount of time before idle connection is closed.
  ## Zero means no limit.
  # idle_conn_timeout = 0

  ## Authentication for Direct Ingestion.
  ## Direct Ingestion requires one of: `token`,`auth_csp_api_token`, or `auth_csp_client_credentials`
  ## See https://docs.wavefront.com/csp_getting_started.html to learn more about using CSP credentials with Wavefront.
  ## Not required if using a Wavefront proxy.

  ## Wavefront API Token Authentication. Ignored if using a Wavefront proxy.
  ## 1. Click the gear icon at the top right in the Wavefront UI.
  ## 2. Click your account name (usually your email)
  ## 3. Click *API access*.
  # token = "YOUR_TOKEN"

  ## Optional. defaults to "https://console.cloud.vmware.com/"
  ## Ignored if using a Wavefront proxy or a Wavefront API token.
  # auth_csp_base_url=https://console.cloud.vmware.com

  ## CSP API Token Authentication for Wavefront. Ignored if using a Wavefront proxy.
  # auth_csp_api_token=CSP_API_TOKEN_HERE

  ## CSP Client Credentials Authentication Information for Wavefront. Ignored if using a Wavefront proxy.

Convert Path & Metric Separator

If the convert_path option is true any _ in metric and field names will be converted to the metric_separator value. By default, to ease metrics browsing in the Wavefront UI, the convert_path option is true, and metric_separator is . (dot). Default integrations within Wavefront expect these values to be set to their defaults, however if converting from another platform it may be desirable to change these defaults.

Use Regex

Most illegal characters in the metric name are automatically converted to -. The use_regex setting can be used to ensure all illegal characters are properly handled, but can lead to performance degradation.

Source Override

Often when collecting metrics from another system, you want to use the target system as the source, not the one running Telegraf. Many Telegraf plugins will identify the target source with a tag. The tag name can vary for different plugins. The source_override option will use the value specified in any of the listed tags if found. The tag names are checked in the same order as listed, and if found, the other tags will not be checked. If no tags specified are found, the default host tag will be used to identify the source of the metric.

Wavefront Data format

The expected input for Wavefront is specified in the following way:

<metric> <value> [<timestamp>] <source|host>=<sourceTagValue> [tagk1=tagv1 ...tagkN=tagvN]

More information about the Wavefront data format is available here

Allowed values for metrics

Wavefront allows integers and floats as input values. By default it also maps bool values to numeric, false -> 0.0, true -> 1.0. To map strings use the enum processor plugin.
