Environment

Release : 10.7.0

Component : Integration with APM

Cause

The APM-ASM server doesn't have direct access to internet without proxy

This is a limitation (DE525498), by design we expect the APM-ASM monitor server to have internet access.

Resolution

Workaround

Contact Broadcom Support for access to a TEST fix available from DE525498

Solution:

This new feature will be part of the next release.
