### 6. Configure Grafana

After Prometheus is configured, you can use Grafana to visualize MinIO metrics. Refer the [document here to setup Grafana with MinIO prometheus metrics](https://github.com/minio/minio/blob/master/docs/metrics/prometheus/grafana/README.md).

                transport.disconnect(true);
                transport.connect(getConfig().getConnTimeout()); // Reconnect
                log.info("Successfully reconnected after witness notification");
            } catch (Exception e) {
                log.error("Failed to reconnect after witness notification", e);
            }
        });
    }

    /**
     * Schedule an address change
     *

        assertNotNull(result);
        assertTrue(result.startsWith("NtTransQuerySecurityResponse["));
        assertTrue(result.endsWith("]"));
    }

    @Test
    @DisplayName("Test getSecurityDescriptor after successful read")
    void testGetSecurityDescriptorAfterRead() throws Exception {
        byte[] buffer = createValidSecurityDescriptorBuffer();

        setErrorCode(response, 0);

            }

            length = (length << 8) + octet;
        } while (++octetsPos < octetsCount);

        if (length >= limit && !isParsing) // after all we must have read at least 1 byte
        {
            throw new IOException("corrupted stream - out of bounds length found: " + length + " >= " + limit);
        }

        return length;
    }

    @Test
    void testEngineReset() {
        // Test engineReset()
        HMACT64 hmac = new HMACT64(TEST_KEY);
        hmac.engineUpdate(TEST_DATA, 0, TEST_DATA.length);
        hmac.engineReset();
        // After reset, should be able to digest again
        byte[] result = hmac.engineDigest();
        assertNotNull(result);
    }

    @Test
    void testEngineGetDigestLength() {
        // Test engineGetDigestLength()

   *
   * Note: The time at which a [call][Call] is considered idle is different depending on whether it
   * was run [asynchronously][Call.enqueue] or [synchronously][Call.execute]. Asynchronous calls
   * become idle after the [onResponse][Callback.onResponse] or [onFailure][Callback.onFailure]
   * callback has returned. Synchronous calls become idle once [execute()][Call.execute] returns.

If you want to use your APIs' function names as `operationId`s, you can iterate over all of them and override each *path operation's* `operation_id` using their `APIRoute.name`.

You should do it after adding all your *path operations*.
