Chapter 7

Viewing and Analysis of Captured Data

52

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).
