ICMP module

The ICMP module processes ICMP traffic. It stores the amount of ICMP 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.

Common types

ICMP statistics common types section

Graphs of more common ICMP types

Traffic graphs for the most common ICMP packet types Destination unreachable, Time exceeded, Echo reply/request and Timestamp reply/request are shown.

Type counters

ICMP statistics type counters section

Distribution of all seen ICMP packets

Packet counters for all different ICMP packet types are shown in the table, with capture buttons for each type to download the specific traffic type as PCAP.

The following types are supported:

Echo Reply
Echo Request
Destination Unreachable
Source Quench
Redirect
Router Advertisment
Router Solicitation
Time Exceeded
Parameter Problem
Timestamp Request
Timestamp Reply
Information Request

Ping times

ICMP statistics ping times section

Ping latency

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

Ping sent from: The IP address that sent an ICMP 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 ICMP request and (usually) sends the ICMP 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 ICMP 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 ICMP requests and their replies in the selected time span.
