IS Freeware NOW!!!

Multiple Interface Watcher
MIW is a graph utility that shows the utilisation of up to 20 different network interfaces. The data is requested from the devices using SNMP. MIW is an advanced development of Interface Traffic Indicator that focuses more on the utilization overview of many interfaces than on much information of one interface.

Please note:
This software has become freeware in 2011. The registration details can be found on the MIW details page.

Interface Traffic Indicator
is a graph utility to measure incoming and outgoing traffic on an interface in bits/sec, bytes/sec or utilization. Works on all SNMP-capable devices (computers, NICs, switches, routers, etc.) with adjustable poll intervall down to three seconds. You can use this program in a professional network environment to monitor selected network interfaces (even backplane ports if the device provides the information) or you can monitor your home network or cable/modem/ISDN connection to the internet.

Performance Pinging
Performance Pinging, a tool for testing availability, response times and performance using ICMP. It writes data to a text file for later interpretation with e.g. Excel. Allows you to change IP address, ICMP timeout and data size during runtime. Comes with a nice little graph for realtime testing. Now includes PerfCopy for testing network performance by copying files to UNC locations.

Version 2.0.1; May 2006 335,912 Bytes

MultiPing Grapher
MultiPing Grapher is a further development of Perfping with the ability to graph up to 10 different ICMP results. Includes logging and average calculation.

Squid Efficiency Analyzer
Squid Efficiency Analyzer interprets a Squid log (native) to determine how much traffic can be retrieved from the cache and how much comes from the web servers in the internet. Tested with log files from Squid 2.5 STABLE 5 for Windows NT 4.0/2000/XP/2003.

FDB Get
This little gadget will try to retrieve the forwarding table entries (Mac to interface number) of switches (layer 2 devices). This comes in handy when you want to know to which interface of a switch a particular NIC (e.g. computer) is attached to. Now suppports parameters for command line use.

Unix Timestamp Converter
UTC is a little utility with only two functions: convert a Unix timestamp (seconds since January 1st 1970 to date) to a human readable DateTime format and vice versa. So simple it does not need a help file or further information.
Includes Delphi source code

Screenshot Grebba
Screenshot Grebba is a little tool that makes screenshots of up to 10 different program windows and displays them on its own webpage. I use it on a server with various monitoring programs to get an overview of what is happening in the network.

StormFinder
Stormfinder is a little utility that requests non-unicast packet statistics from all interfaces of a network device using SNMP. After requesting the number of incoming NU-packets (i.e. broadcasts and multicasts) it does so again after 10 seconds and calculates the difference.
