Time series data refers to the composition of metrics and tags.
A metric is an arrangement of numerical data in a successive time order,
consisting of a title and several time-value pairs.
Usually time series data is enriched by tags.

Regular – data that is sampled at regular intervals. For example every second, or every hour.

Irregular – for example, data that is only recorded when an event occurs, which might happen frequently, but always at completely random times.
