System information endpoints
InfluxDB 3 Clustered provides system endpoints for checking instance availability and retrieving version information.
| Endpoint | Method | Description |
|---|---|---|
/ping | GET, HEAD | Returns 204 if the querier is available. Response headers include X-Influxdb-Version and X-Influxdb-Build. Does not require authentication. Checks querier health only; does not check ingesters. |
To verify ingester availability before writing data, send a request to one of the write endpoints.
