Embodiments of the present disclosure provide a method, an electronic device, and a computer program product for tracing information. The method includes: receiving an information acquisition request from a work container, the information acquisition request comprising information about a workload of the work container; determining, based on the information about the workload, a group to which the workload belongs; determining tracing information corresponding to the group, the tracing information being used for associating a log of the workload with logs of related workloads of the workload; and sending the tracing information to the work container. With the method according to embodiments of the present disclosure, the work container does not need to save a tracing context for each workload. This can save storage space in the work container, even without taking up storage space in the work container.
