Modifying Existing Measures

The MODIFY PARAMETER DETAILS pop up window appears when you click the Modify button available below the measure name in the Measure tab of the NEW TEST DETAILS page. This page allows users to modify the details of the measures that were added earlier:

  • The MEASURE NAME field displays the name that was given to the measurement during creation. The user is permitted to change the name, if required.

  • While adding the measure, the user would have chosen the UNIT (whether %, seconds, requests/sec, etc.) in which the measurement's value is to be reported. The selection made by the user will be displayed in the Unit list, by default. However, you can choose a different unit from the UNIT drop down list.

  • By default, the database column size (i.e. the size of each database record corresponding to a measurement value) chosen by the user while creating the measure, will be listed in the DATABASE COLUMN SIZE list. You can alter the DATABASE COLUMN SIZE, by choosing a different option from this list.

  • If the test type is Script/Batch File, SQL Query or Perfmon, then additionally, the PROCESS METHOD chosen by the user while adding the measure, will also appear. You can change this specification, by selecting an alternate PROCESS METHOD from this list.

  • Sometimes, administrators may want to convert the unit of measurement of a performance metric before displaying the same in the eG monitoring console. For instance, a test may extract an ‘MB’ value from the target server as a measure, but while reporting it in the eG monitoring console the administrators may want the unit of the measure to be changed to ‘KB’ instead. Similarly, a duration value originally available in ‘minutes’, may have to be changed to ‘Secs’ before it is displayed in the console. If you want the unit of the measure being added to be so converted at test run time, then select a Conversion Factor from the list. For example, if a value in ‘Bytes’ needs to be converted to ‘MB’, then select /1048576 (Bytes to MB) as the conversion factor. By default, 1 is chosen as the Conversion Factor; this implies that, by default, unit conversion does not take place for a new measure at test run time. You may modify this Conversion Factor, too using this page.

  • If the test type is Perfmon, then the COUNTER NAME that corresponds to the displayed MEASURE NAME will also appear. You can change the COUNTER NAME, if required. The name of the perfmon counter should be the same as that which appears in the Add Counters dialog box of the Performance console in a Microsoft Windows server.

  • Similarly, if the test type is Snmp, then the OBJECT OID of the measure that was specified during measure creation, will appear here. The user can alter this specification too.

  • Similarly, if the test type is Snmp, then the OBJECT OID of the measure that was specified during measure creation, will appear here. The user can alter this specification too.

  • Likewise, if the test type is Jmx, and the option chosen from the MEASURE SELECTION OPTIONS page is MBean Auto Discovery or Load MBeans From File, then the MBean name and the Attribute name that maps to the measure being modified will automatically be displayed here. If need be, the user can alter these specifications by selecting a different MBean name and Attribute name from the corresponding drop-down lists. On the other hand, if the test type is Jmx, and the option chosen from the MEASURE SELECTION OPTIONS page is Manual Entry, then only the Attribute name that was previously configured for the measure will be displayed here. The user can alter this specification by manually specifying a different attribute name.

  • Once you have modified the required fields, click the MODIFY button in this page to update the changes.
