Specifi es the maximum number of image fi les (based on image fi le seg-
ment size, see Section 3.3.1) that are created on the destination disk. When the number is

’ to fi ll the disk until it reaches capacity.
•
NetCap Snap Size:
Allows you to capture up to the specifi ed amount of bytes of each packet
of data.
•
NetCap Pkt Log Inter:
Allows you to specify the time interval in minutes of how often the Net-
work Tap Module writes its accumulated dropped packet information to the Action log. Setting
this value to ‘0’ disables packet loss reporting.
•
Live Capture:
This service runs continuously in the background and streams captured data in
realtime over the network to a remote monitor using the third-party Wireshark network protocol
analyzer. See Section 3.1.2 for more information.
