Performance of server that is managing a group of servers, such as in a cloud, is analyzed by identifying patterns of threads executed in the server. A command is issued, repeatedly over a time period, to an operating system of the server to return a resource consumption value representative of the amount of computing resources consumed by one or more threads. The returned resource consumption values are stored and used to generate points on a graph which depicts the amount of computing resources consumed by the one or more threads over the time period and provide task breakdowns and latency information for each of the tasks.

Diagnosis of application server performance problems via thread level pattern analysis

A computer implemented method for efficiently allocating resources for an enterprise server system through a proportional integral derivative scheme is provided. The method includes defining a set point parameter for a resource being allocated and defining a proportional gain parameter, a proportional integral (PI) gain parameter and a proportional integral derivative (PID) gain parameter in terms of the proportional gain parameter. The method further includes calculating an initial maximum allocation for the resource based on a product of the proportional gain parameter with a difference of an initial operating parameter and the set point parameter and adjusting the initial operating parameter to the initial maximum allocation. A next allocation of the resource is calculated based on a product of the proportional gain parameter with the difference of an initial operating parameter and the set point parameter and a difference of the set point with a current operating parameter. The initial maximum allocation is adjusted with a next allocation.
