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:
shell
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"
}
}
'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:
shell
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"
}
}
]
