This disclosure has reference to verifying records of system change events in a distributed network system providing cloud services. In one embodiment, the methods and systems observe system update messages sent and received among components of the distributed network system, generate a record of the state of the object in response to the update messages, and compare the record of the state of the object with information from a periodic system status message to verify the accuracy of the periodic system status message. Advantageously, the present embodiments provide increased reliability for system status tracking, resource management, and billing for consumption of resources in distributed network systems. Additional benefits and advantages of the present embodiments will become evident in the following description.

Methods and systems of tracking and verifying records of system change events in a distributed network system

In one embodiment, the methods and systems may include receiving an Application Program Interface (API) request, assigning a unique identifier to the API request, recording, in association with the unique identifier, receipt time corresponding to a time at which the API request is received, and associating one or more system state changes with the unique identifier. Advantageously, the present embodiments provide a more accurate failure monitoring and associated metrics.
