Abstract: Presented are concepts for processing an event log. Once such concept obtains an event log comprising a log of event occurrences for an executed process. It also obtains an events embedding model representative of relationships between a plurality of events of one or more processes. Based on the events embedding model, repeating events in the event log are clustered into one or more groups, and each of the one or more groups are associated with a respective identifier. Repeating events in the event log are then replaced with the identifier associated with the group that the repeating event is a member of.

Abstract: One example method includes performing failure recovery operations in a computing system using matrix clocks. Each node or process in a computing system is associated with a matrix clock. As events and transitions occur in the computing systems, the matrix clocks are updated. The matrix clocks provide a chronological and casual view of the computing system and allow a recovery line to be determined in the event of system failure.

Abstract: Described herein is a method, system, and non-transitory computer readable medium for helping customers in accessing data through an application from a replica database, detecting whether the replica database, zone of availability of the replica database, or geographical region encompassing the zone of availability is experiencing an outage or other failure, and re-routing traffic to a backup replica database accordingly. To assess the status of the database, metrics are pushed in a secure manner from a private subnet to a public-facing monitoring agent, achieving a clear segregation of private subnet and public facing components. Further, circuit-breaker logic is included for preventing failure during updating DNS addresses during the re-routing process.
