Datadog computes an aggregation (whether it is a mean, a sum, a percentile, etc.) by using the set of logs included in the targeted time frame.
Let’s illustrate this on a fictive bar timeline where each bar represents a time interval. In this example, Datadog creates one aggregation for each of the time intervals for the entire set of logs. Note that log events are not necessarily uniformly time-distributed, so you can not necessarily create aggregations for the same amount of logs.
In the following example, each dot represents one log event. The X-axis is the timestamp of the log, and the Y-axis is the value of a duration attribute borne by logs. The timeseries displays a maximum-aggregation. Datadog displays a timeline with a rollout parameter; for example, there are 4 bars for the whole time frame.
