# 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 surround # 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 = "27s" ## 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 ## Maximum number of unwritten metrics per output. 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. 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.
