Explanation
The Resource Monitoring preferences list a JAR file that is required for an instrumented application server type. This JAR file must be mapped to a new location and transferred to the cloud workbench. But this transaction failed, because the file could not be found locally.
System action
Execution in the cloud will continue but the instrumented application server types that require the listed JAR file might fail.
User response
Open the child preference page under Test -> Performance Resource Monitoring. Ensure that the listed files exist and can be found in a valid location.
