• determining, for a given data type pertaining to the first computer node of the network, a first pair of interim limit values usable for data normalization and including a first minimal interim value and a first maximal interim value, wherein at least one of the first minimal interim value and the first maximal interim value depends on computer hardware characteristics or computer software characteristics of the first computer node,
• determining, for said given data type pertaining to the second computer node of the network, a second pair of interim limit values usable for data normalization and including a second minimal interim value and a second maximal interim value, wherein at least one of the second minimal interim value and the second maximal interim value depends on computer hardware characteristics or computer software characteristics of the second computer node,
• wherein the first minimal interim value is different from the second minimal interim value or the first maximal interim value is different from the second maximal interim value,
• normalizing, for each period of time of a plurality of periods of time, a sample of the given data type pertaining to the first computer node, using the first pair of interim values, into a normalization range between a minimal normalization value and a maximal normalization value, to obtain a corresponding normalized sampled value,
• normalizing, for each period of time of a plurality of periods of time, a sample of the given data type pertaining to the second computer node using the second pair of interim values, into said normalization range, to obtain a corresponding normalized sampled value,
• for a given computer node of the first computer node and the second computer node, combining normalized sampled values of different data types of the given computer node into a set of combined node features, the set of combined features comprising a data structure or an image usable, after tagging, as input of the system,
• determining a performance tag indicative of a status related to the network of computer nodes based on said set of combined node features, thereby determining the functionality of said network of computer nodes.
