Adding Monitoring Data

Function

This API is used to add one or more pieces of custom metric monitoring data to solve the problem that the system metrics cannot meet specific service requirements.

URI

POST /V1.0/{project_id}/metric-data

Parameter description

**Table 1** Parameter description
Parameter	Mandatory	Description
project_id	Yes	Specifies the project ID. For details about how to obtain the project ID, see Obtaining a Project ID.

Example

POST https://{Cloud Eye endpoint}/V1.0/{project_id}/metric-data

For details about Cloud Eye endpoints, go to Endpoints to query the URL of each region.

Request

The size of a POST request cannot exceed 512 KB. Otherwise, the request will be denied.
The period for sending POST requests must be shorter than the minimum aggregation period. Otherwise, the aggregated data will be noncontinuous. For example, if the aggregation period is 5 minutes and the POST request sending period is 7 minutes, the data will be aggregated every 10 minutes, rather than 5 minutes.
Timestamp (collect_time) in the POST request body value must be within the period that starts from three days before the current time to 10 minutes after the current time. If it is not in this range, you are not allowed to insert the metric data.

Request parameters

**Table 2** Parameter description
Parameter	Type	Mandatory	Description
Array elements	Array of objects	Yes	Specifies whether to add one or more pieces of custom metric monitoring data. For details, see Table 3.

**Table 3** Array elements
Parameter	Mandatory	Type	Description
metric	Yes	Object	Specifies the metric data. For details, see Table 4.
ttl	Yes	Integer	Specifies the data validity period. The unit is second. Supported range: 1 to 604800 If the validity period expires, the data will be automatically deleted.
collect_time	Yes	long	Specifies when the data was collected. The time is UNIX timestamp (ms) format. NOTE: Since there is a latency between the client and the server, the data timestamp to be inserted should be within the period that starts from three days before the current time plus 20s to 10 minutes after the current time minus 20s. In this way, the timestamp will be inserted to the database without being affected by the latency.
value	Yes	double	Specifies the monitoring metric data to be added, which can be an integer or a floating point number.
unit	No	String	Specifies the data unit. Enter a maximum of 32 characters.
type	No	String	Specifies the enumerated type. Possible types: int float

**Table 4** **metric** data structure description
Parameter	Mandatory	Type	Description
namespace	Yes	String	Specifies the customized namespace. For details, see Services Interconnected with Cloud Eye. The namespace must be in the service.item format and contain 3 to 32 characters. service and item each must start with a letter and contain only letters, digits, and underscores (_). In addition, service cannot start with SYS and AGT, and namespace cannot be SERVICE.BMS because this namespace has been used by the system. You can leave this parameter blank when you set alarm_type to (EVENT.SYS\| EVENT.CUSTOM).
dimensions	Yes	Array of objects	Specifies the metric dimension. A maximum of three dimensions are supported. For details, see Table 5.
metric_name	Yes	String	Specifies the metric ID. For example, if the monitoring metric of an ECS is CPU usage, metric_name is cpu_util. For details, see Services Interconnected with Cloud Eye.

**Table 5** **dimensions** data structure description
Parameter	Mandatory	Type	Description
name	Yes	String	Specifies the dimension. For example, the ECS dimension is instance_id. For details about the dimension of each service, see the key column in Services Interconnected with Cloud Eye. Start with a letter. Enter 1 to 32 characters. Only letters, digits, underscores (_), and hyphens (-) are allowed.
value	Yes	String	Specifies the dimension value, for example, an ECS ID. Start with a letter or a digit. Enter 1 to 256 characters. Only letters, digits, underscores (_), and hyphens (-) are allowed.
