Telegraf metrics

Telegraf metrics are the internal representation used to model data during processing. These metrics are closely based on InfluxDB’s data model and contain four main components:

• Measurement name: Description and namespace for the metric.
• Tags: Key/Value string pairs and usually used to identify the metric.
• Fields: Key/Value pairs that are typed and usually contain the metric data.
• Timestamp: Date and time associated with the fields.

Telegraf metrics exist only in memory and must be converted to a concrete representation to be transmitted or viewed. Telegraf provides output data formats (also known as serializers) for these conversions. Telegraf’s default serializer converts to InfluxDB line protocol, which provides a high performance and one-to-one direct mapping from Telegraf metrics.
