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.
For details about the monitoring data retention period, see How Long Is Metric Data Retained?
Debugging
You can debug the API in API Explorer which supports automatic authentication. API Explorer can automatically generate and debug example SDK code.
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, AGT, or SRE, 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.
