Monitoring using SyRule
SyRule is an innovative component of the SyDat tool suite that provides a unique facility to verify system behaviour in an intelligent way. By examining the interaction of system interfaces according to prescribed relationships born out of the overall system design, SyRule can give an indication of correct system operation.
SyRule measures both the relationship and the time it takes for the relationship to be computed, giving an indication of system performance.
Users create interface relationships (rules) using simple drag and drop, combined with an array of mathematical
functions. Using a C style notation. Rules can be designed to enable and disable other rules or simply use the result of or interface value used by another rule. This allows the user to build complex rule definitions when required.
Intellisense is used to simplify the selection of enumerated values.
At run time, the rules processor produces a summary of the execution of a rule showing the number of times it has passed or failed. Failures are annotated with the data used to evaluate the rule, allowing failure diagnosis.
To further enhance failure analysis SyRule sends commands to SyMon allowing it to bookmark the point of failure in a SyMon log file.
SyRule produces a log file in csv form, allowing it to be imported into Excel for further analysis.
