Monitoring node usage in a distributed system

摘要

One or more service call chains in a distributed service system are identified, each service call chain including one or more service nodes that are sequentially called by clients of the distributed service system. A service call model corresponding to a particular service call chain is generated from the one or more service call chains. Calls to the particular service call chain by the clients of the distributed service system are identified. Performance statistics in the service call model are updated for the particular service call chain, wherein the performance statistics is updated based on the identified calls to the particular service call chain. A performance problem associated with the particular service call chain is identified based on the updated performance statistics. In response to identifying the performance problem associated with the particular service call chain, corrective action for the identified performance problem is initiated.
