Embodiment Construction

[0022] Described below are various embodiments of methods, systems, and computer program products for detecting excessive or abnormal amounts of work assigned to one or more backend servers in a cluster-based application processing environment , and / or detect when a request made on the backend server is incorrectly executed.

[0023] figure 1 is a schematic block diagram of a clustered application processing environment comprising: a plurality of nodes (typically, a physical machine comprising a single node); on each respective node one or more backend computer systems 101 to 105; a deployment manager 120 executing on the computer system 104 to provide a single point of management for the entire cluster; a workload manager 140 executing on the computer system 101 to assign dynamic routing weights to different nodes in the cluster; and Request router 130 , which executes on computer system 105 and acts as a proxy for routing requests to application servers 101 , 102 and 103 in...

Abstract

Methods, systems and computer program products for detecting a workload imbalance in a dynamically scheduled cluster of computer servers are disclosed. One such method comprises the steps of monitoring a plurality of metrics at each of the computer servers, detecting change points in the plurality of metrics, generating alarm points based on the detected change points, correlating the alarm points and identifying, based on an outcome of the correlation, one or more of the computer servers causing a workload imbalance. Systems and computer program products for practicing the above method are also disclosed.

Description

technical field [0001] The present invention relates to the detection of workload imbalances in a dynamically scheduled cluster-based environment, and more particularly to the identification of cluster members responsible for the imbalances. Background technique [0002] Workload scheduling in cluster-based application processing environments (often referred to as "application servers") is typically performed based on a weighted round robin. Typically, routing weights are statically assigned to the various backend servers when the cluster is created. In more recent application servers, route weights are assigned dynamically based on monitored runtime metrics. Dynamic workload scheduling typically considers metrics such as CPU usage on particular servers and response times observed from those servers when assigning routing weights to those servers. [0003] Sometimes, due to a failure in an application on a particular server, or due to an external situation (for example, cu...
