• Packets filtered
— number of filtered (discarded) packets — their source and target
address belongs to the same group or some of these addresses belongs to the
group Discard packet (see chapter 6.1 )
• Too big packets — number of packets that couldn’t be processed because their size
exceeded the maximum size of the cache of the low-level driver of Kerio Network
Monitor . Greater number of these packets can indicate a system error or a possible
attack.
• Transfer failures — number of packets that were not successfully copied from the
internal cache of the network adapter. This error should not occur under normal
circumstances (it can indicate a problem with an adapter or its driver).
• No resources — number of packets that were not successfully processed due to
the lack of system resources.
If this value is in the thousands, Kerio Network Monitor should be installed to a
more powerful computer or to a dedicated computer where no user works.
Disk space used by scanned data The size of disk volume occupied by captured data
from particular services. The number of objects ( Items ) and bytes ( Bytes ) is displayed.
The Sum column contains the total space occupied (sum of all services).
Note: Presented data doesn’t include the space occupied by a database of a volume
of transferred data (i.e. subfolders high and low ).
