Disclosed are various embodiments for a distributed code tracing system that provides code tracing as a service in a multi-tenant computing environment. In one embodiment, a code trace is received that is associated with a request submitted to a particular application hosted in a computing environment, where multiple applications are hosted in the computing environment. The code trace documents calls to multiple component services of the particular application in order to respond to the request. The code trace is then stored in a data store that is indexed by a unique identifier of the request.

Distributed code tracing system

A debugger core captures one or more inputs to a distributed application during live execution of the distributed application in a production environment. The debugger core applies the one or more inputs to the distributed application during replay execution of the distributed application in a debugging environment and performs debugging of the distributed application in the debugging environment.

Disclosed are various embodiments for a distributed code tracing system that provides code tracing as a service in a multi-tenant computing environment. In one embodiment, a code trace is received that is associated with a request submitted to a particular application hosted in a computing environment, where multiple applications are hosted in the computing environment. The code trace documents calls to multiple component services of the particular application in order to respond to the request. The code trace is compressed using time-based compression. The compressed code trace is then stored in a data store that is indexed by a unique identifier of the request.

Disclosed are various embodiments for sampling in a distributed code tracing system. A sampling service receives a segment of a code trace corresponding to a request submitted to a particular application of a plurality of applications hosted in a computing environment. The code trace documents at least one call to at least one component service of the particular application to respond to the request. The sampling service determines whether to forward the segment to a trace processing system or to discard the segment based at least in part on at least one sampling parameter.
