Abstract: One embodiment of the present invention provides a system for identifying undesirable features in a network of computers. During operation, the system detects an anomaly associated with a node in the network. Next, the system identifies one or more features which are associated with the anomaly. The system then updates the identified features. Next, the system communicates the information corresponding to updated features to at least one other node in the network. The system then receives information indicating a correlation between the updated features and the anomaly from at least one other node in the network. Next, the system correlates the updated features with the anomaly based on the received information. The system subsequently produces a result which indicates a correlation between the updated features and the anomaly.

Abstract: A selected time interval of previously stored events generated by a number of computer network devices are replayed and cross-correlated according to rules. Meta-events are generated when the events satisfy conditions associated with one or more of the rules. The rules used during replay may differ from prior rules used at a time when the events occurred within a computer network that included the computer network devices. In this way, new rules can be tested against true event data streams to determine whether or not the rules should be used in a live environment (i.e., the efficacy of the rules can be tested and/or debugged against actual event data).

Abstract: Item values associated with an execution state of a program executed on a computer are collected in detail while suppressing the computer load.

If the computer load is increased, an interval of at least one item is increased. Moreover, there is provided an upper limit for the number of items whose intervals can be reduced simultaneously. Moreover, when varying the interval of the item according to the values of the respective items, the interval variation range is varied according to the item state and the computer load.

Abstract: Embodiments of the present invention provide a system profiler that can be used on any processor architecture. In particular, instead of copying an entire stack every time, the stack is divided into blocks of a fixed size. For each block, a hash value is computed. As stack blocks are sent out of the kernel, the hash value and a copy of the block contents is kept in a user space cache. In the kernel, the hash codes of sent stack blocks are tracked in a table. During system profiling, the kernel module sampling the call stack determines if that stack block was previously sent by checking for the hash value in the kernel table. If the hash matches an entry in the kernel table, then only the hash value is sent. If the hash value is not in the table, the entire block and the hash value is sent.

Abstract: Techniques are described herein that are capable of monitoring activity with respect to a distributed application. A server system includes logical tiers, each including processing system(s) configured to process messages in accordance with a respective protocol (e.g., an ASP.net® protocol, WCF protocol, SQL protocol, etc.). When a user initiates an activity with respect to a distributed application, hops are performed between the logical tiers and/or between components of the distributed application to complete the requested activity. A hop is a transfer of a message or a procedure call from one processing system to another processing system. A common identifier may be assigned to each of the hops that are performed with regard to the activity. If a failure occurs with respect to the activity, the common identifier may be used to gather information regarding the hops. For instance, the information may be used to determine a source of the failure.

Abstract: An example embodiment of the present invention provides processes relating to self-initiated end-to-end monitoring for an authentication gateway. In one particular implementation, the authentication gateway periodically creates and stores a temporary logon for access to a network and then sends a message including the temporary logon over a secure connection to a client. When the client receives the temporary logon, the client responds to the message by attempting to access a configurable network site. The authentication gateway redirects the client to a captive portal which prompts the client for a logon and the client enters the temporary logon at the captive portal. Then upon validating the temporary logon against the stored temporary logon, the authentication gateway authorizes access to the network. If the client successfully accesses the site, the client sends a verification report to the authentication gateway indicating successful access. Otherwise, the client reports on the failed access.

Abstract: An improved method is provided for identifying a cause of a performance problem experienced by an application in a computing environment. To help a user find and isolate the problem quicker, the method proposes a unified performance analysis report that presents the most likely indicators of the source of the performance problem. The report presents performance metrics for the software services used by the application and charts the metric values over time since it is often the change in a metric that indicates a problem. Each metric chart should also include an indicator for the state of service for the application. This will help the user correlate metrics from multiple sources to the time period in which the application experienced a problem.

Abstract: A solution is proposed for implementing a self-adapting reconciliation process. Multiple user accounts are defined on different endpoints for accessing protected resources thereof; a server centralizes the definition of the user accounts on a single point of control which is then synchronized with user account definitions on the endpoints. A dynamic reconciliator, interposed between the server and the endpoints, receives any request from the server for a reconciliation process to be completed in a predefined time-frame. The reconciliator collects the required information from the endpoints and determines an optimal time pattern for the processing of the information by the server over the time-frame according to an estimated amount of information expected to be received and an estimated workload distribution of the server in the time-frame. The reconciliator transmits the information to the server according to this time pattern.
