Abstract: A system and method for generating a service topology graph for microservices in a computing environment uses traces collected from the microservices to generate the service topology graph. The traces are processed to create nodes and edges of the service topology graph. A new node is created when a current trace being processed is a trace being processed for a first time and an edge is created between a node that is associated with a parent span of a current span being processed when the current span is a first span being processed for the current trace and the current span includes a parent span identification.

Abstract: A system and method for managing logs from computing environments uses a rate change in a rate of occurrence of same event type logs from a base time window to a current time window for each of the event types to identify candidate event types for a particular tier log storage. The rate changes of the event types are checked against a threshold rate change range to identify the candidate event types. In response to selection of some of the candidate event types, the logs in the selected candidate event types are transferred to the particular tier log storage.
