Get Points TSDB Meta Data¶
Get the TSDB storage policy corresponding to the model measurement point. A measurement point may have multiple storage policies, depending on its data type and usage. This API returns all the TSDB storage policy metadata in the current OU for the specified measurement point.
Request Format¶
GET https://{apigw-address}/tsdb-policy/v2.0/policies?orgId={}&modelIds={}&measurepoints={}

Sample¶
The following sample shows that the measurement point opentsdb_ai_point_xxx has the storage policies AI_RAW (AI raw data) and AI_NORMALIZED (AI minute-level normalized data):
"opentsdb_ai_point_xxx": [
"AI_RAW",
"AI_NORMALIZED"
]
