Abstract
A method for software performance analysis and debugging in a multi-tenant database network system is provided. In at least one embodiment, sampling is achieved using configuration files of each server cluster. Knowledge of the host names of each server in the cluster enables a profiler to target a single server for each sample, thereby facilitating a round-robin sample across a clustered server environment such that a CPU's load and processing cost associated to sampling is fairly and uniformly distributed across all servers in the cluster. As a result, in at least one embodiment of the analysis and debugging tool each sample is a complete stack trace dump of each thread running on the application server at that moment in time.
