        MetricPublisher.INSTANCE.queryWithMaxExecutionTime()
                .forEach((query, count) -> {
                    new MicrometerMetricsCaptor(meterRegistry)
                            .gaugeBuilder("sql_fetch_time", count, value -> count.intValue())
                            .tag("sql", query)
                            .build();
                });
    }
}

NOTE

The data is added to meter registry every 50 seconds and this will be later available in prometheus.
