Open Source C# Network Monitoring Software for Mac

A network tool to control the bandwidth over your local network, it can block internet access from any selected device, or limit its speed using packet redirection, in addition, it can log web activity for the targeted device using a built-in packet sniffer. Bandwidth limitation for better distribution of internet speed across devices, both upload and download speeds can be controlled for each device separately. A Packet Sniffer that is intended to log addresses that each device on the network visits with the ability to decode Http headers for HTTP packets and resolve domains for HTTPS packets, also the packet direction can be chosen in order to capture requests only or requests and responses.

NOTE: Project has moved to github, including file downloads. SharpPcap is a cross-platform packet capture framework for the .NET environment, based on the famous pcap / WinPcap libraries. It provides an API for capturing, injecting, analyzing and building packets using any .NET language such as C# and VB.NET.

A program designed to get any Windows Perfmon statistic and print it out on the console. Meant to be used as a Cacti plugin ( http://cacti.net/ ) Unfortunately, it is useless if you are running Cacti on Linux.

The IIOP Toolset provides a graphical user interface to analyze end-to-end connectivity thru firewalls and NAT-gateways between the location of CORBA client and the service endpoint of the CORBA server.

Log-CS is a tool for sending logfiles over the net via TCP. This tool contains to applications: LogClient: The LogClient is responsible for sending the logfile over the net. LogServer: The LogServer listens on a choosen port for logfiles.

Linux Traffic Control System for NAT box Statistics Server MultiPlataform Clients Wizard Configuration

A collection of Nagios plugins for various devices, including standard RFC-1628 UPS monitoring, Riverbed SteelHead appliances, Symbol/Motorola wireless networking, IPMI chassis status, and environmental monitoring (EMP) for APC and Powerwave probes.

A proof-of-concept application of the Statistical Protocol IDentification (SPID) algorithm. SPID can detect the application layer protocol (layer 7) by analysing flow (packet sizes etc.) and payload statistics (byte values etc.) from pcap files.

Satellite Restriction Tracker for WildBlue and Exede Internet customers: Log and graph your bandwidth usage, keep track of your limit - now on Linux and macOS! The Satellite Restriction Tracker program automatically grabs and stores your current bandwidth usage every fifteen minutes, showing only a small logo in your system tray while running. When you open the program, you'll see a graph of your current usage, as well as the hard numbers and the time the usage was grabbed. Opening the History window will let you list your usage given all past data, displaying it in easy-to-read graphs or grid representations, helping you map out your bandwidth usage and estimate when your usage values will drop. The graphs can be customized and the program's features are all easily changed from a helpful Configuration window, which also allows you to set up alerts when your usage climbs too fast.

One of the biggest issues we have as ArcSight administrators is knowing what's going on with our connectors. A connector may be "up and running" but actually it has not sent a single event in weeks. Also, many single connectors collect events from multiple locations (multi database, multi file, WUC) and we might never know one of these locations is unavailable as events from the other locations are arriving so the connector seems to be working fine. Eventually, when we do understand that something is wrong, it takes a while to analyze, understand and solve. In light of these problems in the process of error detection in connectors, I have developed is an automated tool named 'We! Analyze' with its own UI which analyzes connector logs manually or using an API that can be started from the command line, a schedule task or from the console with an action in rule, tool or integration command (if you use the API you can forward the events to a syslog listener in CEF format).

Simple - yet powerful and extendable - system monitoring daemon, written completely in managed C#. User interfaces can be attached using various protocols, and new modules (written in any .NET language) can easily be linked to the core monitoring engine.

A minimal .NET binding over WinDivert. Available on Nuget.
