- JSON Structure Parameter Description in body
| Parameter Name | type | Required | Description |
|---|---|---|---|
| queries | array | Y | Multi-command query, its content is a list of query objects |
| fieldTagDescNeeded | boolean | Whether field or tag description information is needed |
- Member Parameter Structure Description of queries[*]
| Parameter Name | type | Required | Description |
|---|---|---|---|
| qtype | string | Y | Query statement type 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 statement | |
| query.ignore_cache | boolean | Whether to disable cache for the query, default is false, meaning use cache | |
| query.promqlType | enum | Effective when qtype=promql, promql query type, optional values instantQuery and rangeQuery, default value is rangeQuery |
|
| query.highlight | boolean | Whether to display highlighted data | |
| query.timeRange | array | Timestamp list for 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 | Re-aggregate modifiers for dql return values, 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 | Pagination size | |
| query.offset | integer | Pagination offset | |
| query.orderby | array | Sort 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.density | string | Response point density, priority 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 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 it is invalid | |
| query.search_after | array | Pagination marker, returned by the current interface as a pagination marker for the next request | |
| 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, higher priority than query.workspaceUUID | |
| query.output_format | string | lineprotocol: Line protocol output, if not filled by default, the existing output format remains unchanged | |
| query.cursor_time | integer | Segment query threshold: When performing the first segment query, cursor_time should be set to end_time; For subsequent segment queries, cursor_time should be set to the next_cursor_time in the response | |
| query.disable_sampling | bool | Sampling disable switch, default value is false |
- Response Point Density
densityParameter Value Description
| Optional Values | Description |
|---|---|
| lower | Lower, 60 points |
| low | Low, 180 points |
| medium | Medium, 360 points |
| high | High, 720 points |
-
Note the priority of the point density parameter, maximum density
density[high]maxPointCount > interval > density > control parameters in the dql statement -
Common Query Description
Note: When performing data queries using the openapi interface, the default role is Administrator. Be aware that data access rules may apply limitations.
