+# Check GreptimeDB Status
+
+GreptimeDB provides a series of HTTP endpoints to query the operational status of GreptimeDB.
+The following HTTP requests assume that GreptimeDB is running on node `127.0.0.1` with the HTTP service listening on the default port `4000`.
+
+## Check if GreptimeDB is running normally
+
+You can use the `/health` endpoint to check if GreptimeDB is running normally.
+An HTTP status code `200 OK` indicates that GreptimeDB is running normally.
+
+Example:
+
+```bash
+curl -i -X GET http://127.0.0.1:4000/health
+HTTP/1.1 200 OK
+content-type: application/json
+content-length: 2
+date: Tue, 31 Dec 2024 02:15:22 GMT
+
+{}
+```
+
+For more information about the health check endpoint, please refer to [the Health endpoint](/reference/http-endpoints.md#health-check).
+
+## Check GreptimeDB status
+
+You can use the `/status` endpoint to check the deployment status of GreptimeDB.
+
+```bash
+curl -X GET http://127.0.0.1:4000/status | jq
