This is a problem of DB design and it should be solved. It is also not possible to combine reports like in V5.
@ Failed / Trace message - some trace messages like "Task failed in the security product" are not telling us why this task failed. You should take more closer look on this.
I will add also something:
Description: LOG deletion uppon Computer deletion
Detail: When I delete computer from ERA console, all coresponding logs in "Threats" are deleted too. This is a "no way" for security product.
