Counting Events and Alarms

Function

This API is used to count events and alarms that meet specified conditions.

Calling Method

For details, see Calling APIs.

URI

POST /v2/{project_id}/events/statistic

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

Project ID obtained from IAM. Generally, a project ID contains 32 characters.

Table 2 Query Parameters

Parameter

Mandatory

Type

Description

type

No

String

Type of information to be queried. active_alert: Active alarms are to be queried. history_alert: Historical alarms are to be queried. If this parameter is not transferred or other values are transferred, information that meets the specified search criteria will be returned.

Enumeration values:

  • history_alert

  • active_alert

Request Parameters

Table 3 Request header parameters

Parameter

Mandatory

Type

Description

X-Auth-Token

Yes

String

User token obtained from IAM.

Content-Type

Yes

String

Content type, which is application/json.

Enumeration values:

  • application/json

Table 4 Request body parameters

Parameter

Mandatory

Type

Description

time_range

Yes

String

Time range specified to query data of the last N minutes when the client time is inconsistent with the server time. It can also be used to accurately query the data of a specified period.

Example:

  • -1.-1.60: indicates that the data of the latest 60 minutes is queried. This query is based on the server time regardless of the current client time.

  • 1650852000000.1650852300000.5: indicates the five minutes from 10:00:00 to 10:05:00 on April 25, 2022 GMT+08:00.

Format:

startTimeInMillis.endTimeInMillis.durationInMinutes

Parameter description:

  • startTimeInMillis: Start time of the query, in milliseconds. If this parameter is set to -1, the server calculates the start time as follows: endTimeInMillis – durationInMinutes x 60 x 1000. For example, -1.1650852300000.5 is equivalent to 1650852000000.1650852300000.5.

  • endTimeInMillis: End time of the query, in milliseconds. If this parameter is set to -1, the server calculates the end time as follows: startTimeInMillis + durationInMinutes x 60 x 1000. If the calculated end time is later than the current system time, the current system time is used. For example, 1650852000000.-1.5 is equivalent to 1650852000000.1650852300000.5.

  • durationInMinutes: Time span, in minutes. The value must be greater than 0 and greater than or equal to the result of "(endTimeInMillis – startTimeInMillis)/(60 x 1000) – 1". If both the start time and end time are set to -1, the system sets the end time to the current UTC time (in milliseconds) and calculates the start time as follows: endTimeInMillis – durationInMinutes x 60 x 1000. For example, -1.-1.60 indicates the latest 60 minutes.

Constraint:

In a single request, the following condition must be met: durationInMinutes x 60/period ≤ 1440

step

Yes

Long

Statistical step (unit: ms). For example, if the statistical step is one minute, set this parameter to 60,000.

search

No

String

Field specified for fuzzy query, which can be left blank. If this field is not left blank, the system will return metadata's mandatory fields that are fuzzily matched.

sort

No

sort object

Sorting order, which can be left blank.

metadata_relation

No

Array of RelationModel objects

Combination of search criteria, which can be left blank.

Table 5 sort

Parameter

Mandatory

Type

Description

order_by

No

Array of strings

List of sorted fields. Fields in this list are sorted based on the specified order.

order

No

String

Sorting order. asc: ascending order. desc: descending order.

Enumeration values:

  • asc

  • desc

Table 6 RelationModel

Parameter

Mandatory

Type

Description

key

No

String

Key specified for query, which corresponds to the key in the metadata.

value

No

Array of strings

Value of the specified key in the search criterion.

relation

No

String

Relationship between search criteria. Values: AND: All criteria must be met. OR: One of the criteria needs to be met. NOT: None of the criteria can be met.

Enumeration values:

  • AND

  • OR

  • NOT
