Detailed Description

Represents a single data point for InfluxDB.

This structure models one point record compatible with the InfluxDB line protocol. Each point consists of a table name (measurement), a set of key–value tags, a set of numeric fields, and an optional timestamp with nanosecond precision.

Member Function Documentation

◆ ToLineProtocol()

std::string rtctk::componentFramework::InfluxPoint::ToLineProtocol ( ) const

Encodes data to InfluxDB line protocol format.

Converts the contents of this structure into a valid InfluxDB line protocol string.

Example output:

metrics,hostname=elthost,metric_type=frequency_estimate value_hz=0 1761206196967207602

Returns: A string containing the encoded line protocol.

Member Data Documentation

◆ fields

std::map<std::string, FieldValue> rtctk::componentFramework::InfluxPoint::fields

Fields hold the measured data values.

They are not indexed.

Example: { "value_hz": 3.2 }.

◆ table_name

std::string rtctk::componentFramework::InfluxPoint::table_name

Name of the table.

Example: metrics, state, cpu_usage.

◆ tags

std::map<std::string, std::string> rtctk::componentFramework::InfluxPoint::tags

Tags are indexed key–value pairs used for efficient filtering.

Example: { "hostname": "server01", "metric_type": "frequency_estimate" }.

◆ timestamp

std::optional<std::chrono::nanoseconds> rtctk::componentFramework::InfluxPoint::timestamp = std::nullopt

Optional timestamp of the measurement.

If not specified, the current server time will be used. Expressed in nanoseconds since the UNIX epoch.
