Issue/Introduction

 Issue/Problem/Symptoms: 

 Seeing an issue with CA CEM when trying to use the transaction discovery, I get the following message: "Limit exceeded adding new components to Discovered  Transactions."

 

 Environment:  

 Linux. APM 10.x.

 

 Cause: 

 By default, up to 50 non-identifying components can be discovered per transaction. After 50 have been discovered, the oldest ones are deleted to allow new ones to  be added. A CA CEM event called "Limit" exceeded adding new components is logged each time a new non-identifying component replaces an old one.

 

 Resolution/Workaround:

 To change the maximum number of non-identifying components, edit the Autogen.Max.NonIdentifying.Components property in tess-customer.properties.

 *tess-customer.properties file should be created as following:

 1. Locate the file:

  <EM_Home>/config/tess-default.properties

 2. Create a copy of the tess-default.properties file in the same directory, and name it tess-customer.properties.

3. Modify the created tess-customer.properties file, adding only the properties needed to modify for your CA CEM environment.

  a. Edit this new properties file.

      For example, using the vi editor:

      vi tess-customer.properties

 

 Important! The tess-customer.properties file should contain only those properties with values that differ from the CA CEM system defaults.

 If you leave all the properties in your tess-customer.properties file, then system upgrades might not take advantage of future system performance or  tuning updates to the properties.

 

b. Save the tess-customer.properties file.

 

4. Copy the tess-customer.properties file to all the Enterprise Managers in the cluster.

 

5. Restart each Enterprise Manager in the cluster.
