Port Number Display Mapping

LogZilla automatically maps port numbers to their respective IANA-Assigned names (see below for a list) to make it more human-friendly when creating UI widgets.

If there is an app or a rule assigned to handle the particular type of log message, LogZilla will read the numeric port number and determine the appropriate service name.

For example, when DstPort or similar user tags are set regarding the network port in the message, it will display the service name rather than the number in widgets on the dashboard.

Here's an example of a pie chart widget and a list widget showing how the port service names would be used rather than the port numbers.

Note that when drilling down into the actual message in the search results, the original log message will be left as-is, showing the numeric port number so that the original message is preserved.

Here's an example showing how the numeric port numbers are retained when examining the log message detail.

IANA-Assigned Ports

TCP and UDP port numbers are generally assigned to specific recipient services or purposes for the connection. Those port assignments are listed below. Please note that some of the port assignments are officially standardized by the Internet Assigned Numbers Authority (IANA), while some have become accepted as common use, but not "officially" assigned by IANA.

Port numbers that are listed twice, mean there are or have been multiple different uses of that same port number by various organizations.

LogZilla maps all of the following port numbers to their respective names. Anything outside of this port range is marked as a "Dynamic" port since there is no official (or unofficial) documentation on that port.
