OpenTSDB

GreptimeDB supports ingesting OpenTSDB via HTTP API.

GreptimeDB also supports inserting OpenTSDB metrics via HTTP endpoints. We use the request and response format described in OpenTSDB's /api/put.

The HTTP endpoint in GreptimeDB for handling metrics is /opentsdb/api/put

Note: remember to prefix the path with GreptimeDB's http API version, v1.

Starting GreptimeDB, the HTTP server is listening on port 4000 by default.

Use curl to insert one metric point:

curl -X POST http://127.0.0.1:4000/v1/opentsdb/api/put -d '
{
    "metric": "sys.cpu.nice",
    "timestamp": 1667898896,
    "value": 18,
    "tags": {
       "host": "web01",
       "dc": "hz"
    }
}
'

Or insert multiple metric points:

curl -X POST http://127.0.0.1:4000/v1/opentsdb/api/put -d '
[
    {
        "metric": "sys.cpu.nice",
        "timestamp": 1667898896,
        "value": 1,
        "tags": {
           "host": "web02",
           "dc": "hz"
        }
    },
    {
        "metric": "sys.cpu.nice",
        "timestamp": 1667898897,
        "value": 9,
        "tags": {
           "host": "web03",
           "dc": "sh"
        }
    }
]
