ICMP module

The ICMP module processes ICMP and ICMPv6 traffic. It stores the amount of ICMP/ICMPv6 traffic and extracts information about the type.

Generic

ICMP statistics module

ICMP generic graph

The ICMP generic traffic graph shows the amount of all ICMP packets and throughput in bit/s over time. Global counters show the corresponding aggregated numerical values.

ICMPv6 generic graph

The ICMPv6 generic traffic graph shows the amount of all ICMPv6 packets and throughput in bit/s over time. Global counters show the corresponding aggregated numerical values.

Ping times

ICMP statistics ping times section

Ping latency

Here are all seen ping peers stored. A ping peer is an IP address (either IPv4 or IPv6 address) sending Echo request(s) and the corresponding destination IP address sending the Echo reply/replies.

• Ping sent from: The IP address that sent an Echo request (see Common table columns - IP).
• Latest request time: This is the time, when the request packet was seen. If more than one packet has been seen, the latest timestamp is shown.
• Ping sent to: The IP address that receives the Echo request and (usually) sends the Echo reply (see Common table columns - IP).
• Latest reply time: This is the time, when the reply packet was seen. If more than one packet has been seen, the latest timestamp is shown.
• Ping latency (min/avg/max): This is the statistical minimum/average/maximum latency between Echo requests and their replies in the selected time span.
• Number of ping requests: This is the total amount of ping requests sent from the requesting IP to the receiving IP address.
• Number of ping replies: This is the total amount of ping replies sent from the IP, that received a request, to the requesting IP address.
• Graph: This graph shows the response time latency history between Echo requests and their replies in the selected time span.
