Types

type AgentConfig 

type AgentConfig struct {
	// Interval at which to gather information
	Interval Duration

	// RoundInterval rounds collection interval to 'interval'.
	//     ie, if Interval=10s then always collect on :00, :10, :20, etc.
	RoundInterval bool

	// Collected metrics are rounded to the precision specified. Precision is
	// specified as an interval with an integer + unit (e.g. 0s, 10ms, 2us, 4s).
	// Valid time units are "ns", "us" (or "µs"), "ms", "s".
	//
	// 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.
	Precision Duration

	// CollectionJitter 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.
	CollectionJitter Duration

	// CollectionOffset is used to shift the collection by the given amount.
	// This can be used to avoid many plugins querying constraint devices
	// at the same time by manually scheduling them in time.
	CollectionOffset Duration

	// FlushInterval is the Interval at which to flush data
	FlushInterval Duration

	// FlushJitter Jitters 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
	FlushJitter Duration

	// MetricBatchSize is the maximum number of metrics that is written to an
	// output plugin in one call.
	MetricBatchSize int

	// MetricBufferLimit is the max number of metrics that each output plugin
	// will cache. The buffer is cleared when a successful write occurs. When
	// full, the oldest metrics will be overwritten. This number should be a
	// multiple of MetricBatchSize. Due to current implementation, this could
	// not be less than 2 times MetricBatchSize.
	MetricBufferLimit int

	// FlushBufferWhenFull tells Telegraf to flush the metric buffer whenever
	// it fills up, regardless of FlushInterval. Setting this option to true
	// does _not_ deactivate FlushInterval.
	FlushBufferWhenFull bool `toml:"flush_buffer_when_full" deprecated:"0.13.0;1.30.0;option is ignored"`

	// TODO(cam): Remove UTC and parameter, they are no longer
	// valid for the agent config. Leaving them here for now for backwards-
	// compatibility
	UTC bool `toml:"utc" deprecated:"1.0.0;option is ignored"`

	// Debug is the option for running in debug mode
	Debug bool `toml:"debug"`

	// Quiet is the option for running in quiet mode
	Quiet bool `toml:"quiet"`

	// Log target controls the destination for logs and can be one of "file",
	// "stderr" or, on Windows, "eventlog".  When set to "file", the output file
	// is determined by the "logfile" setting.
	LogTarget string `toml:"logtarget"`

	// Name of the file to be logged to when using the "file" logtarget.  If set to
	// the empty string then logs are written to stderr.
	Logfile string `toml:"logfile"`

	// The file will be rotated after the time interval specified.  When set
	// to 0 no time based rotation is performed.
	LogfileRotationInterval Duration `toml:"logfile_rotation_interval"`

	// The logfile will be rotated when it becomes larger than the specified
	// size.  When set to 0 no size based rotation is performed.
	LogfileRotationMaxSize Size `toml:"logfile_rotation_max_size"`

	// Maximum number of rotated archives to keep, any older logs are deleted.
	// If set to -1, no archives are removed.
	LogfileRotationMaxArchives int `toml:"logfile_rotation_max_archives"`

	// Pick a timezone to use when logging or type 'local' for local time.
	LogWithTimezone string `toml:"log_with_timezone"`

	Hostname     string
	OmitHostname bool

	// Method for translating SNMP objects. 'netsnmp' to call external programs,
	// 'gosmi' to use the built-in library.
	SnmpTranslator string `toml:"snmp_translator"`

	// Name of the file to load the state of plugins from and store the state to.
	// If uncommented and not empty, this file will be used to save the state of
	// stateful plugins on termination of Telegraf. If the file exists on start,
	// the state in the file will be restored for the plugins.
	Statefile string `toml:"statefile"`

	// Flag to always keep tags explicitly defined in the plugin itself and
	// ensure those tags always pass filtering.
	AlwaysIncludeLocalTags bool `toml:"always_include_local_tags"`

	// Flag to always keep tags explicitly defined in the global tags section
	// and ensure those tags always pass filtering.
	AlwaysIncludeGlobalTags bool `toml:"always_include_global_tags"`
