Protocol Monitor

The Monitor > Real Time Charts > Protocol Monitor page displays real-time charts showing ingress and egress traffic rates for the following protocols:

IPv4 Rate	Internet Protocol version 4
ARP Rate	Address Resolution Protocol, used by IPv4 to map IP network addresses to link layer hardware addresses
IPv6 Rate	Internet Protocol version 6
UDP Rate	User Datagram Protocol, a connection-less protocol used for example by DNS, SNMP, RIP, DHCP
TCP Rate	Transmission Control Protocol, a connection oriented protocol allowing bidirectional traffic once the connection is established, used for example by FTP, SSH, Telnet, and also by DNS
ICMP Rate	Internet Control Message Protocol, used by network devices to send error messages and operational information; ping uses ICMP to send echo request packets to a host
IGMP Rate	Internet Group Management Protocol, used by hosts and routers to establish multicast group memberships

The seven real-time charts displayed on the Protocol Monitor page are shown in the images below. The Ingres rate is displayed on the top half of each chart, and the Egress rate is displayed on the bottom.

A chart may be empty or blank if there are no recent data entries received within the viewing range.
