Parameter Additional Explanation

Query Description

  1. Parameter Description
Parameter Name type Required Description
queries array Y Multi-command query, its content is a list composed of query objects
fieldTagDescNeeded boolean Whether to need field or tag description information
  1. Structure Description of queries[*] Member Parameters *** Note, the async_id parameter has been added based on the "DQL Data Query" interface ***
Parameter Name type Required Description
async_id string N Asynchronous query task ID, this value comes from the content.data[*].async_id in the previous DQL query result; if the previous query response contains this value, then this query must include this value
qtype string Y Type of the query statement
dql: Indicates a DQL type query statement;
promql: Indicates a PromQl type query statement
query json Y Query structure
query.q string Query statement consistent with the qtype type, such as DQL or PromQL query statements
query.ignore_cache boolean Whether to disable cache for the query, default is false, which means using cache
query.promqlType enum Effective when qtype=promql, PromQL query type, optional values are instantQuery and rangeQuery, default value is rangeQuery
query.highlight boolean Whether to display highlighted data
query.timeRange array List of timestamps for the time range
query.disableMultipleField bool Whether to enable single-column mode, default is true
query.showLabel bool Whether to display object labels, default is none
query.funcList array Further aggregate and modify the return values of DQL, note that this parameter is invalid when disableMultipleField=False
query.slimit integer Time series grouping size, only effective for Metrics queries
query.soffset integer Time series grouping offset
query.limit integer Page size
query.offset integer Page offset
query.orderby array Sorting list, {fieldName:method} , note that sorting for Measurement queries only supports fieldName=time; method in ["desc", "asc"]; note that sorting for Measurement queries only supports fieldName=time
query.sorderby array Sorting list, sorderby's column is an expression supporting all aggregation functions that return a single value: min max last avg p90 p95 count, {fieldName:method}, structure is consistent with orderby
query.order_by array Sorting list, structure is [{"column": "field", "order": "DESC"}], Doris engine compatible field
query.sorder_by array Sorting list, structure is [{"column": "field", "order": "DESC"}], Doris engine compatible field
query.density string Point density of the response, priority is less than autoDensity and greater than the density set in the DQL statement
query.interval integer Unit is seconds, time slice interval used to calculate the number of response points; if the calculated number of points is less than or equal to the number of points when density=high, it is valid, otherwise invalid
query.search_after array Pagination query marker. Use the search_after value from the previous request's response as the parameter for this request with identical parameters.
query.maxPointCount integer Maximum number of points
query.workspaceUUID string UUID of the workspace to be queried
query.workspaceUUIDs array UUIDs of the workspaces to be queried, takes precedence over query.workspaceUUID
query.output_format string lineprotocol: Line protocol output, default remains unchanged if not specified
query.cursor_time integer Segment query threshold: When performing the first segment query, set cursor_time to end_time; for subsequent segment queries, set cursor_time to the next_cursor_time in the response
query.disable_sampling bool Sampling disable switch, default value is false
  1. Description of Response Point Density density Parameter Values
Optional Value Description
lower Lower, 60 points
low Low, 180 points
medium Medium, 360 points
high Low, 720 points

  • Note the priority of point density parameters, maximum density density[high] * maxPointCount > interval > density > control parameters in the DQL statement

  • Unrecovered Event Query Note: When performing data queries using the openapi interface, the default role is Administrator. Be aware that data access rules may apply restrictions.
