To modify the mapping of normalized metric family variables, edit the vendor certification expressions.
Consider the following information when you edit expressions:
  • Use delimiters to separate vendor certification variables.
  • MVEL functions and custom functions are valid.
  • The Names and Indexes metric names require an expression. The remaining metric names are optional.
For a vendor certification created with the Vendor Certification wizard,
CA Performance Management
automatically provides the Indexes metric expression for your selected MIB table.
 
Example: Change the Value for Averages
Cisco router CPU statistics are mapped to the normalized variable 'CPU Utilization', as shown in the following expression:
cpmCPULoadAvg5min+cpmCPUUseravg5min
You can change the 5-minute average to a 1-minute average by editing the expression as follows:
cpmCPULoadAvg
1min
+cpmCPUUseravg
1min
Example: Use an Advanced Expression
The following expression verifies whether hrStorageSize < 0, and returns the value of hrStorageSize converted to an Unsigned value, and multiplied by 100. Otherwise, the expression returns the following value: hrStorageUsed/hrStorageSize * 100.
(hrStorageSize &lt; 0) ? (hrStorageUsed/convertSignedIntToUnsignedDecimal(hrStorageSize)) * 100 : hrStorageUsed/hrStorageSize * 100
