The value is a number that is sampled at a point in time, but it is reported as a maximum Gauge value to the backend. This ensures that only the maximum value observed during a reporting interval is sent to the backend, thus over-riding the last-write-wins semantics of standard Gauges. Unlike standard Gauges, Max Gauges do not continue to report to the backend, and there is no TTL.

Call Set() with a value:

```cpp

include

int main() { auto config = Config(WriterConfig(WriterTypes::UDP)); auto r = Registry(config);

// Option 1: Directly create a Max Gauge
auto serverQueueSize = r.CreateMaxGauge("server.queueSize");
serverQueueSize.Set(10);

// Option 2: Create a Gauge from a MeterID
auto serverQueueMeter = r.CreateNewId("server.queueSize");
r.CreateMaxGauge(serverQueueMeter).Set(10);

} ```
