From Pandora FMS version 5 onward, when creating fictitious Agents, you have to take into account that the nomenclature that the .data files that arrive to the Tentacle directory must follow must follow this pattern: name_agent.numbers.data
Example:
pandora_agent.3123278534.data
Any other format that follows can suppose that the data_server does not capture the information and leaves the XML stored in the directory.
