Query Historical Measurement Point¶
Get the time series data of measurement points by object instance IDs.
Request Format¶
GET/POST https://{api-gateway}/cds-timeseries-service/v1.0/tsdb-detail?action=query
Request Parameters¶
Name |
Location |
Mandatory/Optional |
Data Type |
Description |
---|---|---|---|---|
orgId |
Query |
Mandatory |
String |
The organization ID which the measurement point belongs to. How to get orgId >> |
mdmIds |
Query/Form |
Mandatory |
String |
The object instance ID which the measurement point belongs to. Separate multiple IDs by commas. Up to 20000 object instances are allowed in a single query. To ensure query performance, it is recommended that you pass in no more than 100 object instances in a single query. |
pointIdsWithLogic |
Query/Form |
Mandatory |
String |
The measurement point ID with aggregation logic. Format: Function(pointId). Separate multiple IDs by commas, for example, sum(pointId1),sum(pointId2). Up to 100 measurement points are allowed in a single query. The supported aggregation calculation methods include count, avg, sum, max, min, first, last. The time range for the aggregation query is [startTime,endTime), that is, the aggregation operand contains the data at the time of “startTime”, but does not contain the data at the time of “endTime”.

startTime |
Query/Form |
Mandatory |
String |
The start time of the sampling data. Use this format when querying data in local time: yyyy-MM-dd HH:mm:ss; use this format when querying data in UTC time: yyyy-MM-ddTHH:mm:ssZ. For local time format, Common Data Service queries the data by the local time of where each asset is located. |
endTime |
Query/Form |
Mandatory |
String |
The end time of the sampling data. Its format must be consistent with “startTime”. Make sure the number of days between “startTime” and “endTime” is not greater than 90. |
interval |
Query/Form |
Mandatory |
Integer |
The time granularity by which the measurement point is aggregated. The following intervals are supported: RAW (raw data), 1m (1 minute), 5m (5 minutes), 10m (10 minutes), 15m (15 minutes), 30m (30 minutes), H (hour). Make sure the calculated value of this formula is not greater than 12000: (endTime-startTime) / interval, that is the number of the designated time granularity between “startTime” and “endTime” is not greater than 12000. |
pageSize |
Query/Form |
Optional |
Integer |
The number of the returned records on a single page for a single measurement point of a single device. Make sure the calculated value of this formula is not greater than 120000: mdmIds * pointIdsWithLogic * pageSize. |
autoInterpolate |
Query/Form |
Optional |
Boolean |
Whether to return the latest data in the past if no data is found. The default value is false. |
withQuality |
Query/Form |
Optional |
Boolean |
Whether to return the data quality tag. The default value is false. |
