Troubleshooting: Failure to Create Vendor Certification

Symptom:

I tried to create a vendor certification and received an error message that it failed.

Solution:

Open the karaf log files in the Data Aggregator installation directory, and follow these steps:

1. Look for the MIB name string or the name of the metric family you selected.
2. Review the stack trace of the exception and look for the CertManagerException and the reason for the error. The reason for the error follows the exception.

   Example: The expression parser did not expect the token after ++, as shown:

   Caused by: com.ca.im.dm.certmgr.interfaces.CertManagerException: Tech Cert: {http://im.ca.com/normalizer}NormalizedCPUInfo, Unable to compile expression: [Error: expected end of statement but encountered: e]
   [Near : {... stemID ++ extremeSystemBoardID ....}]
   

3. Fix the error based on the reason provided. Verify that the following requirements are met:
   • The expression group must not contain a mix of scalar and table entries.
   • Expressions must contain valid syntax.
   • At least one expression is defined for a metric family variable.
   • At least two metric family variables are defined; specifically Names and Indexes are required (except for scalar-only metrics).
   • The vendor certification variable used in the expression must be from the chosen MIB table (valid in the user interface).
