Post-deployment monitoring of server performance
First Claim
1. A system for monitoring a server from a plurality of locations on a computer network, the system comprising:
- a plurality of agent computers coupled to a computer network, each of the agent computers having an agent component installed thereon, the agent component including functionality for accessing server systems over the computer network as simulated users, and for monitoring and reporting performance of such server systems; and
a controller component that provides functionality for a user to define a monitoring session in which a selected group of the agent computers access and monitor a target server system, wherein the controller component includes a user interface through which the user can select individual agent computers from said plurality of agent computers to include in the group, and individually assign to each selected agent computer one or more transactions that specify simulated user actions, whereby the user of the controller component can define a monitoring session in which different agent computers simulate different user interactions with the target server system.

Abstract
A monitoring system allows users to monitor the performance of a web-based or other transactional server. The system includes an agent component (“agent”) which simulates the actions of actual users of the transactional server while monitoring the server'"'"'s performance. The agent may run on agent computers at a variety of locations. Using a controller component of the system, a user can preferably select a group of agent computers to include in a monitoring session, and assign transactions and execution schedules to such computers. Performance data collected from the agent computers is displayed by a web-based reports server that provides features for viewing the data as seen by agent computers having specific attributes or attribute sets. The system also includes features for capturing and displaying screens returned by the transactional server on failed transactions, and for measuring and reporting segment delays between an agent computer and the transactional server.

monitor a path delay between the first agent computer and the target server system; and
when the path delay satisfies a pre-specified condition, measure and report segment delays along a path between the first agent computer and the target server system.

14. A computer-implemented method of facilitating creation by a user of a monitoring session in which agent computers access and monitor a target server system over a computer network, the method comprising:
-
providing a user interface through which the user may select a group of agent computers to use for the monitoring session;
displaying the agent computers selected by the user as respective nodes within an expandable tree representation of the monitoring session;
presenting to the user a display of transactions, and an option to selectively assign one or more of the transactions to each agent computer in the group, wherein each transaction specifies one or more request messages for accessing the target server as a simulated user; and
in response to user assignment of a transaction to a selected agent computer, displaying the transaction within the expandable tree representation as a child of the selected agent computer. - View Dependent Claims (15, 16, 17)
providing a user interface through which the user may assign execution schedules to the agent computers in the group; and
in response to user assignment of an execution schedule to the selected agent computer, displaying the execution schedule within the expandable tree representation as a child of the selected agent computer.

17. A computer program stored on a computer readable medium which embodies the method of claim 14.
-
18. An agent component that is adapted to run on a networked computer to remotely monitor operation of a server system, the agent component stored on a computer readable medium and configured to:
-
execute a transaction as a simulated user of the server system;
store a sequence of screens displays returned by the transactional server during execution of the transaction;
determine whether the transaction completed successfully; and
if the transaction did not complete successfully, forward the sequence of screen displays to a repository for subsequent viewing. - View Dependent Claims (19, 20)

21. A method of facilitating user analysis of operation of a transactional server, the method comprising:
-
collecting performance data generated by a plurality of agent computers that are programmed to access the transactional server as simulated users that execute transactions, said performance data including transaction pass/fail data, and including screen displays returned by the transactional server; and
displaying the performance data, including the transaction pass/fail data, within an online report that provides a user option to drill down to view a sequence of said screen displays that correspond to a transaction failure, whereby a user can view a sequence of server responses associated with the transaction failure. - View Dependent Claims (22, 23)

24. An automated method of monitoring operation of a server system as seen from an agent computer at a remote location, the method comprising, on the agent computer:
-
accessing the server system as a simulated user while monitoring a path delay between the agent computer and the server system;
when the path delay satisfies a pre-specified condition, measuring a delay along each segment of a network path between the agent computer and the server system, to thereby generate a plurality of segment delay measurements; and
reporting the segment delay measurements to a central monitoring component that receives data reported by a plurality of agent computers. - View Dependent Claims (25, 26)

27. A system for monitoring performance of a server system, comprising:
-
a plurality of agent computers that access the server system over a computer network as simulated users and report performance data resulting therefrom, wherein the agent computers have assigned thereto attributes from each of a plurality of attribute categories; and
a reports server that collects the performance data reported by the plurality of agent computers, and displays the performance data in an aggregated form;
wherein the reports server (1) provides a user option to specify an attribute set that includes attributes from each of the plurality of attribute categories, whereby a user may specify an attribute-based subset of the plurality of agent computers, and (2) generates an attribute-filtered view of the performance data indicative of how the server system is collectively seen by the attribute-based subset of agent computers. - View Dependent Claims (28, 29, 30)
