Techniques that enable a user or customer at a system site to review and, if desired, modify data identified at the system site for transmission to a diagnosis site prior to the transmission. The identified diagnostic data may be modified such that data that the user does not want to be sent to the diagnosis site (e.g., sensitive data) is excluded from the data communicated to the diagnosis site. The data may be modified by removing or excluding the sensitive data from the data that is communicated to the diagnosis site or replacing the sensitive data with non-sensitive data. The modified data may then be communicated from the system site to the diagnosis site in the form of a package.

Scrubbing and editing of diagnostic data

An infrastructure is provided for gathering diagnostic data that is relevant to an error or other conditions detected in a monitored system. A diagnosability framework is provided that automates the gathering of relevant diagnostic data upon occurrence of the condition in the monitored system. In one embodiment, context data is determined for the condition detected in the monitored system. A rule-based engine is provided that is configured to automatically determine one or more actions to be performed for the condition detected in the monitored system based on the determined context data. The actions may include performing tasks that gather diagnostic data that is relevant to the detected condition, store the gathered diagnostic data in a repository, recommend one or more diagnostic actions to a user, and other diagnostic related actions.

User-triggered diagnostic data gathering

Rule-based engine for gathering diagnostic data

Techniques for intelligently identifying diagnostic data to be communicated from a product or system site (e.g., a customer site) to a diagnosis site (e.g., a vendor site). An appropriate amount of diagnostic data is identified to facilitate efficient and quick diagnosis and error resolution. Techniques are also provided that enable a customer to review the data identified for transmission to the diagnosis site prior to the transmission.

Intelligent collection of diagnostic data for communication to diagnosis site

Techniques for controlling collection of diagnostic data in a monitored system. A set of flood control rules are configured for the monitored system for controlling the gathering of diagnostic data in the monitored system. The set of flood control rules may include one or more default flood control rules. The set of flood control rules are user-configurable enabling the user of the monitored system to set policies for dynamically controlling gathering of diagnostic data for the monitored system. In one embodiment, diagnostic data gathering is controlled based upon a number of previous occurrences of a condition in some predefined or user-configured time frame that triggers diagnostic data gathering and/or a number of previous executions of an action performed in some predefined or user-configured time frame responsive to the condition in the monitored system.

Diagnosability system: flood control

Gathering context information used for activation of contextual dumping

Techniques for systematically gathering, organizing, and storing diagnostic data related to multiple monitored systems (e.g., multiple instances of a product or multiple products). A centralized repository is provided that is organized in a hierarchical manner to facilitate proper organization of the diagnostic data related to multiple monitored systems. In one embodiment, a root directory comprising one or more subdirectories is provided for storing diagnostic data collected for each monitored system. Multiple root directories may be provided under a common base directory for storing diagnostic data corresponding to multiple monitored systems. This enables correlation of diagnostic data across multiple monitored systems.

Diagnostic data repository

Techniques for non-intrusive performance of diagnostic actions including actions that result in gathering of diagnostic data in response to a condition detected in a monitored system. In one embodiment, the diagnostic actions are performed asynchronously by processes or threads that are different from the failing process or thread that receives or detects the condition that triggers the diagnostic actions such that the failing process or thread can continue processing without being affected by the executions of the diagnostic actions. Multiple asynchronous processes or threads that are different from the failing process or thread may be spawned to perform multiple diagnostic actions in parallel. The asynchronous processes or threads may be monitored to ensure that they do not adversely impact the monitored system.

Non-intrusive gathering of diagnostic data using asynchronous mechanisms

Techniques for gathering information during runtime of a monitored system such that the information is available for facilitating diagnostics for the monitored system. In one embodiment, upon detection of a condition (such as an error condition) in the monitored system, a portion of the gathered information provides contextual information that facilitates gathering of diagnostic data that is relevant for the detected condition. This facilitates capturing of diagnostic data that is relevant for diagnosing the detected condition. The information gathered and stored during runtime may include information related to local variables, information related to tagged information (e.g., tagged functions/processes) executing in the monitored system, information related to potential impacts to the monitored system due to failures, metadata information, and other information.

Gathering information for use in diagnostic data dumping upon failure occurrence

A diagnosability system for automatically collecting, storing, communicating, and analyzing diagnostic data for one or more monitored systems. The diagnosability system comprises several components configured for the collection, storage, communication, and analysis of diagnostic data for a condition detected in monitored system. The diagnosability system enables targeted dumping of diagnostic data so that only diagnostic data that is relevant for diagnosing the condition detected in the monitored system is collected and stored. This in turn enables first failure analysis thereby reducing the time needed to resolve the condition detected in the monitored system.
