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, which can be obtained from the console or by calling an API. For details, see Obtaining a Project ID.

**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. For details, see Obtaining a Token.
Content-Type	Yes	String	Message body type or format. 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 (UTC) of the query, in milliseconds. If this parameter is set to -1, the server calculates the start time as follows: endTimeInMillis – durationInMinutes × 60 × 1000. For example, -1.1650852300000.5 is equivalent to 1650852000000.1650852300000.5. endTimeInMillis: end time (UTC) of the query, in milliseconds. If this parameter is set to -1, the server calculates the end time as follows: startTimeInMillis + durationInMinutes × 60 × 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: query time span, in minutes. The value must be greater than 0 and greater than or equal to the result of (endTimeInMillis – startTimeInMillis)/(60 ×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 × 60 × 1000. For example, -1.-1.60 indicates the latest 60 minutes. Constraint: In a single request, the following condition must be met: durationInMinutes × 60/period ≤ 1,440
step	No	Long	Statistical step. Unit: ms. For example, if an alarm is cleared after 1 minute, set this parameter to 60000. Min.: 1 minute.
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	Yes	String	Key specified for query, which corresponds to the key in the metadata. This parameter is mandatory if metadata_relation is not empty.
value	No	Array of strings	Value of the specified key in the search criterion.
relation	No	String	Relationship between search criteria. 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
