Deprecated

Use metrics() or single_metric() instead

get_metrics()

pytest_userver.client.ClientMonitor.get_metrics	(		self,
			prefix = None )

Deprecated

Use metrics() or single_metric() instead

metrics()

metric_module.MetricsSnapshot pytest_userver.client.ClientMonitor.metrics	(		self,
		*typing.Optional[str]	path = None,
		typing.Optional[str]	prefix = None,
		typing.Optional[typing.Dict[str, str]]	labels = None )

Returns a dict of metric names to Metric.

Parameters

path	Optional full metric path
prefix	Optional prefix on which the metric paths should start
labels	Optional dictionary of labels that must be in the metric

Definition at line 432 of file client.py.

metrics_diff()

'MetricsDiffer' pytest_userver.client.ClientMonitor.metrics_diff	(		self,
		*typing.Optional[str]	path = None,
		typing.Optional[str]	prefix = None,
		typing.Optional[typing.Dict[str, str]]	labels = None,
		bool	diff_gauge = False )

Creates a MetricsDiffer that fetches metrics using this client.

It's recommended to use this method over metrics to make sure the tests don't affect each other.

With diff_gauge off, only RATE metrics are differentiated. With diff_gauge on, GAUGE metrics are differentiated as well, which may lead to nonsensical results for those.

Parameters

path	Optional full metric path
prefix	Optional prefix on which the metric paths should start
labels	Optional dictionary of labels that must be in the metric
diff_gauge	Whether to differentiate GAUGE metrics

async with monitor_client.metrics_diff(prefix='foo') as differ:
    # Do something that makes the service update its metrics
assert differ.value_at('path-suffix', {'label'}) == 42

metrics_raw()

typing.Dict[str, Metric] pytest_userver.client.ClientMonitor.metrics_raw	(		self,
		str	output_format,
		*typing.Optional[str]	path = None,
		typing.Optional[str]	prefix = None,
		typing.Optional[typing.Dict[str, str]]	labels = None )

Low level function that returns metrics in a specific format.

Use metrics and single_metric instead if possible.

Parameters

output_format	Metric output format. See server::handlers::ServerMonitor for a list of supported formats.
path	Optional full metric path
prefix	Optional prefix on which the metric paths should start
labels	Optional dictionary of labels that must be in the metric

Definition at line 485 of file client.py.

single_metric()

typing.Optional[Metric] pytest_userver.client.ClientMonitor.single_metric	(		self,
		str	path,
		*typing.Optional[typing.Dict[str, str]]	labels = None )

Returns the Metric.

Parameters

path	Full metric path
labels	Optional dictionary of labels that must be in the metric

Exceptions

AssertionError

if more than one metric or no metric found

Definition at line 468 of file client.py.

single_metric_optional()

typing.Optional[Metric] pytest_userver.client.ClientMonitor.single_metric_optional	(		self,
		str	path,
		*typing.Optional[typing.Dict[str, str]]	labels = None )

Either return a Metric or None if there's no such metric.

Parameters

path	Full metric path
labels	Optional dictionary of labels that must be in the metric

Exceptions

AssertionError

if more than one metric returned
