Modifying Existing Measures

This page appears when the MODIFY button against a newly added measure name in the ADD MEASURES page is clicked. It allows users to modify the following measure details:

  • The MEASURE NAME field displays the name that was given to the measurement during its 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 user's selection will appear in this page. However, it can be changed by selecting a different UNIT from the list of units provided in the drop-down list.

  • 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 appear in this page. The user can alter the DATABASE COLUMN SIZE, by choosing a different size option from the associated drop-down 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 here. The user can change this specification, by selecting an alternate PROCESS METHOD from the associated drop-down 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.

  • If the test type is Perfmon, then the COUNTER NAME that corresponds to the displayed MEASURE NAME will also appear. The user 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 all the required modifications are made, click the MODIFY button in this page to update the changes.
