Statistics are metric data aggregations over specified periods of time. When you graph or retrieve the statistics for a metric, you specify the Period of time, such as five minutes, to use to calculate each statistical value. For example, if the Period is five minutes, the Sum is the sum of all sample values collected during the five-minute period, while the Minimum is the lowest value collected during the five-minute period. Percentile (p) indicates the relative standing of a value in a dataset. For example, p95 is the 95th percentile and means that 95 percent of the data within the period is lower than this value and 5 percent of the data is higher than this value. Percentiles help you get a better understanding of the distribution of your metric data.

Create a metric filter on the log data. Percentile (p) indicates the relative standing of a value in a dataset. For example, p95 is the 95th percentile and means that 95 percent of the data within the period is lower than this value and 5 percent of the data is higher than this value.
