a. Definition – Statistic Collectors user definable rules that capture a data point at a given period of time. The result of the analysis rule is chart a graphical view the data point over time. The results of the Statistic can also be used in analysis rules.
i. Name – User defined name
ii. Description – User defined description of the statistic
iii. Type – Currently Perl is the only supported statistic type. Required.
iv. Execution Interval – Choose a period for a Statistic from 1 minute to 1 week. The time that passes between intervals should be accurate to one second of the last run execution.
v. Active – Only active Statistic collectors will be executed. Rules are set to Inactive by the system if they have an execution error, including syntax problems or exceeding the execution interval.
vi. Rule Definition – Text Area where the statistic is defined. See appendix B, statistic definition guide, for the rules and conventions of writing statistics.
Error – The Error field is filled out when an error
occurs executing the statistic. When a
user corrects the error, and clicks the
Active flag on the analysis rule, the Error field filled out by the system is removed.
viii. Launch Debugger – This option executes the debugger.exe. debugger.exe should reside in the path pointed to by the Virtual Administrator option – Edit System Settings > System Variables > Install Path. If there is no debugger.exe in that install path on the machine which the button is clicked, the debugger can not be used. Since the install path variable is also used to point to the lib directory for the Central Server, most users find it most convenient to only debug analysis rules and statistics on the same machine that Central Server is installed on. See appendix C, debugger options, for more information about using the debugger.
i. Add – Creates new Analysis Rule
ii. Import – Opens dialog box to browse for an Analysis Rule defined in XML format.
iii. Export – Selected analysis rule will be exported to a XML file. Multiple analysis rules can be selected for export by pressing shift or ctrl.
