TAMI II for System Logs

  1. Problem and Motivation

Log files can be viewed as a systematic record keeping of activities perform on a particular computer system, these logs can be examined to monitor, or audit subsystems, users and networks, files transfer, network activities, intrusion detection, hardware and software errors. All Linux and Unix servers possess logging capability and generate log messages that informs the user of server health and used to help diagnose the server whenever problems arise or has the potential to, and also used to help in the prognosis to determine the corrective action. Considering how thorough a log management system can perform, it can collect more data than can be reasonably analyzed by human effort and in many situations, analysis is only performed after some computer problem has occurred. Log management and log analysis is an integral part of maintaining server health. The volume, quantity, and variety of logs aforementioned can become so large on just one server that it could take hours, days, and even weeks to manually parse to adjudicate the server’s condition.

What’s more, if that in an enterprise environment there’s a multitude of servers, some with multiple roles. These servers run day and night nonstop, which means logs are generated on a continuous basis. This makes the adjudication process even more problematic. This may often require external data-mining and analytics as the only feasible course for analysis. In many situations, whatever analysis is performed is done only after some computer problem has occurred. 

  1. S.O.S (System Operational Status) Histories


(Fitness  Assessment in Computing Environment)

F.A.C.E. is software that analyzes the state of the devices and applications of a computer system. It determines whether the devices and applications are in warning, bad or serious working condition within a user defined interval. An icon FACE will indicate the general state of the computer system.  The FACE will be in the state of:

  1. FINE (Fitness In Normal Environment) and its various states

  2. FROWN (Fitness as the Result  Of Working Negatively) and its various states

in a Unix and MAC personal computer systems environments. MAC or TUX (Linux) FACE will then report to the user which devices and apps are in a FROWN state. The user will be presented with a visual summary or can examine the log messages directly.

(Transcript Analysis Mining Interpretation Software System)

We perform content analysis on digital transcripts of structured and semi-structured documents such as trial transcripts, surveys, hearings, interviews, interrogations, emails, and system logs (Epistemic Logging). By using text and data mining, concept/entity identification, sophisticated natural language processing, and knowledge representation methods, our TAMI software systems extract propositional knowledge, relationships and classifications then creates high quality visual summaries and visualizations.
