Free network monitor process software for linux

Network Probe and protocol analyzer is the ultimate tool for traffic-level network monitoring, troubleshooting, analysis,
If your network is crawling to a standstill, and you suspect there might be a problem with the network traffic, Network Probe will quickly help you identify what is causing the problem, show you who is generating any troublesome traffic, and where the traffic is being transmitted.
Network Probe will collect traffic statistics for all protocols, hosts, and conversations on your network, and show you all the top talkers and listeners on your network. Hosts generating large amounts of traffic such as music and movie streaming, playing online games, or listening to streaming media are easily identified.
Main features:
- Watch in real time which protocols are used on your network
- Watch in real time which hosts are active on your network and the Internet
- Watch in real time which conversations are taking place on your network and to and from the Internet
- Watch in real time detailed protocol statistics per host
- Watch in real time detailed protocol statistics per conversation
- Watch in real time network card details for your network
- Watch traffic amount of selected entries relative to the total and filtered traffic
- Watch traffic amount over time for any host, conversation, and protocol
- Watch in real time network throughput for the entire network segment
- Inspect detailed logged statistical data from days and weeks earlier
- Filter out and search for selected protocols, hosts, conversations, and network cards
- Sort network traffic by amount of data transmitted or received
- Export network traffic statistics data
- Configure users with restricted access to statistical data
- Password protected login

NAT Monitor is a tool to monitor hosts bandwidth usage in a Linux-NAT network.

A daemon collects data and clients display them (currently a GTK app with graph and a text version). It detects new hosts, saves up to 12 hours of data, and has a nice summary statistic.

Network Time Tools (NTT) is a set of network tools designed to provide monitoring of a network and the services on that network, and provide various reports on the hosts/services and optional alerts via email, pager, and cellphones. It also has the capability to send messages on user-specified services to email, pagers and cell phones.
Main features:
- Bandwidth measurement based on time intervals
- Checks Service availibilty on specified Hosts for the following protocols:
- ftp
- ssh
- telnet
- dns
- http ( specific pages )
- www ( simple head )
- pop
- nntp
- imap
- irc
- smtp
- Ability to send alerts based on user specified services to:
- pagers
- cell phones
- email
- A frontend that displays a daily report that can be viewed by a web browser or cell phone.
- views specific servers
- views specific services
- views bandwidth measurements
- view alerts
- Data stored in a Mysql Database
- Easily configurable via an XML config file
- Runs in Daemon or one-shot mode

Network Management Center project is a comprehensive network device management tool. After entering each network device, every detail can be tracked and monitored.
Having this information accessible simplifies the process of troubleshooting a network.
Manage your network with a free web-based network management tool. Troubleshooting your network will become much easier with all your network information just a few clicks away.
Add all your network devices and monitor the details about each device, and any changes that are made to the network device. Multi permission levels allow complete control over the system.
Keep your network organized and under control, network management software is based on PHP and MySQL.
Enhancements:
- Some bugs found in the forms library for the network management center software were fixed.

Manage your network with a free Network Monitoring Software application.
Network Management Tool is an organized way to manage your network. 100% web-based network management.
Manage your network devices with ease. 100% Free Network Managment Software! Manage all your network devices, routers, switches, firewalls, hubs, and more.
Enhancements:
- A display bug that occurred when viewing the comments on a device was fixed.

The Monitor application, which consists of 2 parts, a MonitorServer (linux daemon) and a MonitorClient (java gui), will enable the user to monitor and log server process, memory, network and cpu information of multiple servers at a time.

The MonitorClient part is written in Java and is able to connect to one or more Servers that are running the MonitorServer part of the Monitor application.

The client will poll the servers at user specified intervals and will provide a graphical representation of the recources (mem, cpu, nic and process information) of one server at a time.

In addition the MonitorClient is able to log the information of all the servers, each server in a different logfile in a coprehesive CSV format.

The MonitorServer is a seperate application written in C++ and linked to omniORB4 to minimize the load it imposes on the server that is beeing monitored. When the MonitorServer is not beeing polled by a MonitorClient it sits idle.

The client will of course run on any platform that supports Java, but the server currently only supports Linux, kernels 2.2, 2.4, 2.6 and possibly (not tested) 2.0 and >2.6.

Simple Monitor is a SuperKaramba theme inspired by the simple but effective "Very Simple Monitors" theme by the user humanthing. Some values are not displayed properly though in Very Simple Monitors (network values and IP). This could be because of different setups. My computer is pretty standard so my theme should function properly on most pcs. http://www.kde-look.org/content/show.php?content=48973
I like a tight and clean desktop, so I simplified the idea even more. This theme is showing all basic information, and nothing more.
Main features:
- Processors type
- Processor speed
- Processor load (number and graph, for one proc)
- Processor Temperature
- Amount of ram used / amount of ram
- amount of swap used / amount of swap
- amound of HDD space used / amount of HDD space total (for "/root" and "/home")
- HDD temperatue (for "/hda", I could add another drive if requested)
- Computer name
- Computer ip
- Network load (up- and download, values and graph)
- Amount of transfered data thrue internet (up- and download) since last boot
Enhancements:
- Made the three blocks clickable.
- The CPU block opens Processor information
- The Memory block opens KsysGuard (youll need to have it installed to be able open it, obviously. Its in Kubuntu by default)
- the Network block opens your computers ip settings window
- Added a line for your computers uptime
- Changed font colors to very dark gray and very light gray, instead of black and white, to make it look softer.
