apache_beam.metrics.monitoring_infos.int64_user_gauge(namespace, name, metric, ptransform=None)

Return the gauge monitoring info for the URN, metric and labels.

Parameters:

• namespace – User-defined namespace of counter.
• name – Name of counter.
• metric – The GaugeData containing the metrics.
• ptransform – The ptransform id used as a label.

apache_beam.metrics.monitoring_infos.int64_gauge(urn, metric, ptransform=None)

Return the gauge monitoring info for the URN, metric and labels.

Parameters:

• urn – The URN of the monitoring info/metric.
• metric – An int representing the value. The current time will be used for the timestamp.
• ptransform – The ptransform id used as a label.

apache_beam.metrics.monitoring_infos.create_monitoring_info(urn, type_urn, payload, labels=None)

Return the gauge monitoring info for the URN, type, metric and labels.

Parameters:

• urn – The URN of the monitoring info/metric.
• type_urn – The URN of the type of the monitoring info/metric. i.e. beam:metrics:sum_int_64, beam:metrics:latest_int_64.
• payload – The payload field to use in the monitoring info.
• labels – The label dictionary to use in the MonitoringInfo.

apache_beam.metrics.monitoring_infos.is_counter(monitoring_info_proto)

Returns true if the monitoring info is a coutner metric.

apache_beam.metrics.monitoring_infos.is_gauge(monitoring_info_proto)

Returns true if the monitoring info is a gauge metric.

apache_beam.metrics.monitoring_infos.is_distribution(monitoring_info_proto)

Returns true if the monitoring info is a distrbution metric.

apache_beam.metrics.monitoring_infos.is_user_monitoring_info(monitoring_info_proto)

Returns true if the monitoring info is a user metric.

apache_beam.metrics.monitoring_infos.extract_metric_result_map_value(monitoring_info_proto)

Returns the relevant GaugeResult, DistributionResult or int value.

These are the proper format for use in the MetricResult.query() result.

apache_beam.metrics.monitoring_infos.parse_namespace_and_name(monitoring_info_proto)

Returns the (namespace, name) tuple of the URN in the monitoring info.

apache_beam.metrics.monitoring_infos.get_step_name(monitoring_info_proto)

Returns a step name for the given monitoring info or None if step name cannot be specified.

apache_beam.metrics.monitoring_infos.to_key(monitoring_info_proto)

Returns a key based on the URN and labels.

This is useful in maps to prevent reporting the same MonitoringInfo twice.
