Abstract

The invention discloses a data sampling method and a device, electronic equipment and a storage medium, and relates to the field of data processing. The data sampling method comprises the steps of: dividing a data sequence into a plurality of data groups; for each data packet, calculating data in the data packet by adopting a preset algorithm, and taking a calculation result as sampling data of the data packet; and outputting the sampling data of each data group. According to the method of the invention, error data can be conveniently positioned.

Description

technical field [0001] The present application relates to a computer field, in particular to a data processing field. Background technique [0002] When performing data analysis on a large amount of data, data sampling is often used to sample a part of the data from the large amount of data, and display and / or analyze the sampled data. This random sampling method often ignores the problematic data, resulting in the inability to accurately locate the problematic data. [0003] For example, time series data (also called time series data) is a collection of data collected in chronological order by a certain indicator. The amount of time-series data generated by operation and maintenance monitoring is generally relatively large, especially when the selected time range is relatively large, and all the data cannot be displayed on a limited screen, so the original data needs to be sampled. For example, the current screen can only display 1000 data, but the original data transmitt...
