Hi, 

My discovery schedules are getting cancelled and I need to findout defective IPs. previously, I find out through ECC Queue tab where processed column is empty but not discoveries are still getting canceled and processed have timings so unable to findout IP who is responsible. So, please let me know how should I find it in least time.
