# 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.
|
|
#
|
|
# Environment variables can be used anywhere in this config file, simply prepend
|
|
# them with $. For strings the variable must be within quotes (ie, "$STR_VAR"),
|
|
# for numbers and booleans they should be plain (ie, $INT_VAR, $BOOL_VAR)
|
|
|
|
|
|
# Global tags can be specified here in key="value" format.
|
|
[global_tags]
|
|
# dc = "us-east-1" # will tag all metrics with dc=us-east-1
|
|
# rack = "1a"
|
|
## Environment variables can be used as tags, and throughout the config file
|
|
# user = "$USER"
|
|
|
|
|
|
# Configuration for telegraf agent
|
|
[agent]
|
|
## Default data collection interval for all inputs
|
|
interval = "{{ stat_collection_interval }}"
|
|
## Rounds collection interval to 'interval'
|
|
## ie, if interval="10s" then always collect on :00, :10, :20, etc.
|
|
round_interval = true
|
|
|
|
## Telegraf will send metrics to outputs in batches of at most
|
|
## metric_batch_size metrics.
|
|
## This controls the size of writes that Telegraf sends to output plugins.
|
|
metric_batch_size = 1000
|
|
|
|
## For failed writes, telegraf will cache metric_buffer_limit metrics for each
|
|
## output, and will flush this buffer on a successful write. Oldest metrics
|
|
## are dropped first when this buffer fills.
|
|
## This buffer only fills when writes fail to output plugin(s).
|
|
metric_buffer_limit = 10000
|
|
|
|
## 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"
|
|
|
|
## By default or when set to "0s", precision will be set to the same
|
|
## timestamp order as the collection interval, with the maximum being 1s.
|
|
## ie, when interval = "10s", precision will be "1s"
|
|
## when interval = "250ms", precision will be "1ms"
|
|
## Precision will NOT be used for service inputs. It is up to each individual
|
|
## service input to set the timestamp at the appropriate precision.
|
|
## Valid time units are "ns", "us" (or "µs"), "ms", "s".
|
|
precision = ""

## Logging configuration:
|
|
## Run telegraf with debug log messages.
|
|
debug = false

## Run telegraf in quiet mode (error log messages only).
|

quiet = true

## Specify the log file name. The empty string means to log to stderr.
