What’s a Registry Trigger?

Log triggers are predetermined circumstances that signal a software application to create a log report of recent events on a system. They generate event logs that provide end users with a history of significant events within the software. Log triggers help computer specialists troubleshoot serious problems.

A log trigger is a predetermined circumstance or set of circumstances that signals a software application to create a log report of recent events on your system. Included in the software by its original programmers, log triggers typically assist the end user of a program by generating meaningful error reporting data, as well as providing other pertinent messages, including debugging and conflict information. While largely meaningless to those without at least a basic technical background, a registry trigger can typically help computer specialists when serious problems arise by allowing them to see exactly what has been going on within a program before a serious accident or other unforeseen event.

Log triggers generate event logs on computer hard drives. An event log is a file generated by a program to provide end users with a history of significant events within the software. Think of these as a list of minutes from a meeting: a summary of the most relevant issues is included. The end user can normally access the event log like any other file on the system, allowing him to review the day’s or week’s events.

Software programmers generally include a registry trigger within their crash sequences or error sequences. When a program encounters an error, it uses the crash sequence by default, aiming to shut down without causing significant damage to the computer or its files. At this point, it runs the trigger script, writing the root cause of the failure to a file so that the user can store the information for troubleshooting.

Without a working log trigger, it would be difficult to discover the root cause of an error. Using a log trigger, end users can rely on log files to detect patterns over a longer period of time, looking for commonalities behind program errors. For example, the end user might discover conflicts between two or more programs, pinpointing situations where crashes are much more likely to occur. In the absence of this level of dedicated analytics, however, log triggers aren’t overtly useful to software users.
