OpenTelemetry Task Metrics Setup.

Module

Functions

get_installation_uuid

def get_installation_uuid(    storage_path: pathlib.Path = PosixPath('/Users/merlin/.bitfount'),) ‑> str:

Return the installation UUID.

get_task_meter

def get_task_meter() ‑> TaskMeter:

Fetch global TaskMeter.

setup_opentelemetry_metrics

def setup_opentelemetry_metrics(    *, session: BitfountSession,) ‑> None:

Setup Open Telemetry metrics exporter and TaskMeter.

Global variables

• task_meter : Optional[TaskMeter] - The OpenTelemetry Python SDK doesn't seem to have a way to unregister callbacks, (https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/api.md#asynchronous-gauge-operations) so to avoid creating a new gauge and registering a new callback that will have a reference kept my OpenTelemetry (memory leak) every time we instantiate a Protocol we have this global Meter that can be used by all Protocol instances.

Classes

BitfountOLTPMetricsExporter

class BitfountOLTPMetricsExporter(    *,    session: BitfountSession,    endpoint: str,    insecure: bool,):

OTLPMetricExporter that sends Bitfount session headers.

The BitfountSession message_service_metadata property may change over time so we need to ensure we have it fresh when we export metrics.
