# Telegraf configuration

# Telegraf is entirely plugin driven. All metrics are gathered from the
# declared inputs, and sent to the declared outputs.

# Plugins must be declared in here to be active.
# To deactivate a plugin, comment out the name and any variables.

# Use 'telegraf -config telegraf.conf -test' to see what metrics a config
# file would generate.

# Global tags can be specified here in key="value" format.
[global_tags]
  # location of the data centre
  location="{{LOCATION}}"
  # media service template id
  sfc="{{SFC_ID}}"
  # media service instance
  sfc_i="{{SFC_ID_INSTANCE}}"
  # service function type
  sf="{{SF_ID}}"
  # service function instance id
  sf_i="{{SF_ID_INSTANCE}}"
  # ipendpoint id aka surrogate instance
  ipendpoint="{{IP_ENDPOINT_ID}}"

# Configuration for telegraf agent
[agent]
  ## Default data collection interval for all inputs
  interval = "10s"
  ## Rounds collection interval to 'interval'
  ## ie, if interval="10s" then always collect on :00, :10, :20, etc.
  round_interval = true

  ## Telegraf will cache metric_buffer_limit metrics for each output, and will
  ## flush this buffer on a successful write.
  metric_buffer_limit = 1000
  ## Flush the buffer whenever full, regardless of flush_interval.
  flush_buffer_when_full = true

  ## Collection jitter is used to jitter the collection by a random amount.
  ## Each plugin will sleep for a random time within jitter before collecting.
  ## This can be used to avoid many plugins querying things like sysfs at the
  ## same time, which can have a measurable effect on the system.
  collection_jitter = "0s"

  ## Default flushing interval for all outputs. You shouldn't set this below
  ## interval. Maximum flush_interval will be flush_interval + flush_jitter
  flush_interval = "10s"
  ## Jitter the flush interval by a random amount. This is primarily to avoid
  ## large write spikes for users running a large number of telegraf instances.
  ## ie, a jitter of 5s and interval 10s means flushes will happen every 10-15s
  flush_jitter = "0s"

  ## Logging configuration:
  ## Run telegraf in debug mode
  debug = false
  ## Run telegraf in quiet mode
  quiet = false
  ## Specify the log file name. The empty string means to log to stdout.
  logfile = "/var/log/telegraf/telegraf.log"

  ## Override default hostname, if empty use os.Hostname()
  hostname = ""
