Abstract
Data replication groups may be used to store data in a distributed computing environment. The data replication groups may include a set of nodes executing a consensus protocol to maintain data durably. In order to monitor and debug the operation of the data replication group a chaining mechanism may be utilized during log creation by the set of nodes of the data replication group. The chaining mechanism may cause entries in the log to indicate an operation being performed and an operation performed immediately prior to the operation being performed. In various embodiments, an outside observer receives the logs and checks the logs for errors indicated by the chaining mechanism.
