What is the sampling period of DCGM about dcgm HOT 1 CLOSED

@FlyHuss,

Update Frequency - how often DCGM will read the hardware counters (metric values)
Max Keep Age - how long will a metric value with a timestamp be kept in the internal cache. There is an API to get metric values since some timestamps in the past, not just the latest value.
Max Keep Samples - how many metric values should be kept in the internal cache.
The DCGM will compute how many metric values are kept in the cache based on those argument values and select the biggest/longest result.
For example, if you specify frequency = 1sec, maxKeepAge = 300sec, and maxKeepSamples = 500, then DCGM will keep 500 metric values, and with 1sec frequency, that will be 500sec of historical values.
On the other hand, if you specify maxKeepSamples = 1, then DCGM will keep 300sec of historical values, which at 1sec frequency corresponds to 300 metric values.

I hope that clarifies the meaning of the arguments.
