 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."



 Linux. APM 10.x.



 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.



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

 * file should be created as following:

 1. Locate the file:


 2. Create a copy of the file in the same directory, and name it

3. Modify the created 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:



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

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


b. Save the file.


4. Copy the file to all the Enterprise Managers in the cluster.


5. Restart each Enterprise Manager in the cluster.
