Diagnosis (artificial intelligence) As a subfield in artificial intelligence, diagnosis is concerned with the development of algorithms and techniques that are able to determine whether the behaviour of a system is correct. If the system is not functioning correctly, the algorithm s ...

Event correlation Event correlation is a technique for making sense of a large number of events and pinpointing the few events that are really important in that mass of information. This is accomplished by looking for and analyzing relationships between events. Hi ...

Fault management In network management, fault management is the set of functions that detect, isolate, and correct malfunctions in a telecommunications network, compensate for environmental changes, and include maintaining and examining error logs, accepting and ...

Fault tree analysis Fault tree analysis (FTA) is a type of failure analysis in which an undesired state of a system is examined. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the ...

Grey problem In IT, a grey problem (or, gray problem) is a problem where the causing technology is unknown or unconfirmed. Common grey problems are: * Intermittent errors; * Intermittent incorrect output, or; * Transient performance problems. Because the cau ...

RPR problem diagnosis Rapid problem resolution diagnosis (or RPR diagnosis) is a method of problem diagnosis designed to determine the root cause of IT problems. History The method was originally developed by Advance7 in 1990 as Advanced Network Troubleshooting, with ...

Remote diagnostics Remote diagnostics is the act of diagnosing a given symptom, issue or problem from a distance. Instead of the subject being co-located with the person or system done diagnostics, with remote diagnostics the subjects can be separated by physical di ...

Root cause analysis In science and engineering, root cause analysis (RCA) is a method of problem solving used for identifying the root causes of faults or problems. It is widely used in IT operations, manufacturing, telecommunications, industrial process control, ...

Troubleshooting Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process ope ...

Unified Diagnostic Services Unified Diagnostic Services (UDS) is a diagnostic communication protocol used in electronic control units (ECUs) within automotive electronics, which is specified in the ISO 14229-1. It is derived from ISO 14230-3 ( KWP2000) and the now obsolete ...
