OpenTSDB API Introduction
OpenTSDB provides HTTP-based or HTTPS-based APIs. A request method is to send a standard HTTP request containing the GET and POST methods to a path of a resource. The API is the same as that of the open source OpenTSDB. For details, visit https://opentsdb.net/docs/build/html/api_http/index.html.
The request and response entity type is application/JSON.
The code of the request and response entity is ISO-8859-1.
HTTP has security risks and HTTPS is a secure protocol. You are advised to use HTTPS for connection.
Common OpenTSDB APIs are as follows:
- Writing Data
- Querying Data
- Querying the First Piece of Data
- Querying the Last Piece of Data
- Managing the Data Lifecycle
