According to a sample embodiment, a method is provided for capturing context information about an event. A data collector is created comprising instructions to collect specific context data in response to specific conditions in a call stack, and the data collector is registered with a first failure data capture application. In a sample embodiment the first failure data capture application receives a registration for a context data collector. Then, in response to being called, the first failure data capture application looks for at least one of a class and a method defined in the context data collection registration that matches conditions of the call stack. In response to said call stack conditions being met, the first failure data capture application calls the data collector to collect context data from the call stack, receives context data from the context data collector; and presents the context data.

Capturing context information in a currently occurring event

Problem diagnostics may be obtained from components that log messages using a unique component identifier which is provided within each message so as to enable routing of callbacks to the component that originated the message. Similarly, problem diagnostics may be obtained from components that generate alerts, where the alerts contain the unique identifier of the component that generated the alert. Each component supports a diagnostic provider interface comprising operations which may be dynamically invoked, for example to solicit information from the component such as its configuration data, its state information, to execute self-diagnostic tests, and so forth. In addition or instead, operations may be provided that can be invoked to cause the component to alter its configuration data (such as notifying the component to change its level of message logging) or its behavior.
