Querying Metrics in a Specified Period¶

Function¶

This API is used to query metrics of a function in a specified period.

URI¶

GET /v2/{project_id}/fgs/functions/{func_urn}/statistics/{period}

**Table 1** Path Parameters¶
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID. For details, see Obtaining a Project ID.
func_urn	Yes	String	Function URN. For details, see the function model description.
period	Yes	String	Time range specified to query function execution metrics.

Request Parameters¶

**Table 2** Request header parameters¶
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	User token. It can be obtained by calling the IAM API used to obtain a user token. The value of X-Subject-Token in the response header is the user token.
Content-Type	Yes	String	Message body type (format).

Response Parameters¶

Status code: 200

**Table 3** Response body parameters¶
Parameter	Type	Description
count	Array of SlaReportsValue objects	Function invocations.
duration	Array of SlaReportsValue objects	Average latency, in milliseconds.
fail_count	Array of SlaReportsValue objects	Number of errors.
max_duration	Array of SlaReportsValue objects	Maximum latency, in milliseconds.
min_duration	Array of SlaReportsValue objects	Minimum latency, in milliseconds.
reject_count	Array of SlaReportsValue objects	Number of throttles.
function_error_count	Array of SlaReportsValue objects	Number of function errors.
system_error_count	Array of SlaReportsValue objects	Number of system errors.
reserved_instance_num	Array of SlaReportsValue objects	Reserved instance metrics.
concurrency_num	Array of SlaReportsValue objects	Elastic instance metrics.

**Table 4** SlaReportsValue¶
Parameter	Type	Description
timestamp	Integer	Timestamp.
value	Double	Value. If the value is -1, the metric has no data in the current period. The possible cause is that the function is not executed.
