Abstract

Described is a method that provides a better way to track events that need to be logged (usually for servicability purposes). In addition to the specifics of the events and their related data being logged, the device's cumulative power-on time is also logged. This additional information creates the opportunity to correlate events (especially failure events) with the device's operating time and more accurately identify trends and patterns. This method considers two ways to use power-on-time time stamps: Have the accumulated power-on-time time stamp as the only time stamp Have the accumulated power-on-time time stamp in addition to a time-of-day time stamp. Some specific way to use these logs with their time stamps are:

ADVANCED HISTORICAL LOG IN A DEVICE

   Described is a method that provides a better way to track events that need to
be logged (usually for servicability purposes). In addition to the specifics
of the events and their related data being logged, the device's cumulative
power-on time is also logged. This additional information creates the
opportunity to correlate events (especially failure events) with the device's
operating time and more accurately identify trends and patterns.

This method considers two ways to use power-on-time time stamps:

Have the accumulated power-on-time time stamp as the only time stamp
Have the accumulated power-on-time time stamp in addition to a time-of-day
time stamp.

Some specific way to use these logs with their time stamps are:

Error logs displayed, printed, or otherwise shown to humans for their
examination and use
Error logs sent to other devices for processing
Error logs made accessible for reading by other devices which may process
them
Processing logs to discern trends and predict future events, based on the
accumulated power-on-time data
Scheduling maintenance actions based on such processing
