Enhanced distributed tracing

A computer system for enhanced distributed tracing, the computer system comprising:

• a communication fabric;
• one or more computer-readable storage media connected to the communication fabric, wherein the one or more computer-readable storage media collectively store program instructions;
• and
• one or more processors connected to the communication fabric, wherein the one or more processors execute the program instructions to:
• identify a set of microservices in a sequence of microservices preceding a preselected microservice in the sequence of microservices;
• identify each tracing data sample received from the set of microservices preceding the preselected microservice in the sequence of microservices;
• and
• delete each tracing data sample corresponding to a set of selected transactions received from the set of microservices preceding the preselected microservice in the sequence of microservices that was dropped during rate-limiting sampling performed by the preselected microservice based on analysis of a result of the rate-limiting sampling of the set of selected transactions received from the preselected microservice thereby retaining a subset of tracing data samples corresponding to the set of selected transactions collected during head-based sampling.

A computer program product for enhanced distributed tracing, the computer program product comprising one or more computer-readable storage media having program instructions collectively stored therein, the program instructions executable by one or more processors to cause the one or more processors to:

• identify a set of microservices in a sequence of microservices preceding a preselected microservice in the sequence of microservices;
• identify each tracing data sample received from the set of microservices preceding the preselected microservice in the sequence of microservices;
• and
• delete each tracing data sample corresponding to a set of selected transactions received from the set of microservices preceding the preselected microservice in the sequence of microservices that was dropped during rate-limiting sampling performed by the preselected microservice based on analysis of a result of the rate-limiting sampling of the set of selected transactions received from the preselected microservice thereby retaining a subset of tracing data samples corresponding to the set of selected transactions collected during head-based sampling.
