What is Network Monitoring

Network monitoring simply means the use of a system that constantly
monitors a computer network for slow or failing components and that
notifies the network administrator in case of outages via email, SMS or
other alarms.

Many a times the data that is sent from one computer to another over
the wire or wireless network are hacked. So network monitoring becomes
very essential for any network administrator. So network administrators
implements various things and also uses some tools in order to monitor
the network. Many a times network administrator simply fiddle around to
get a best solution which can give all the information whatever he
needs. So here is a small guide providing all the software with a
detail information to monitor your network.

1. Intellipool Network Monitor
Intellipool Network Monitor is a network, server and performance
monitor designed to monitor Windows, Linux, Unix and SNMP enabled
devices. It is commercial software developed and sold by Intellipool
AB, Sweden. It is a system for agentless server monitoring, alerting
and reporting of a large selection of operating systems and SNMP
capable devices. Intellipool Network Monitor is administrated through a
web interface and is installed as a service on a computer running
Windows 2000, XP or 2003.

Intellipool Network Monitor features:

  • The best operating system monitoring support in the industry Windows,
    Linux, Solaris, BSD to just name a few, in total 14 different operating
    system supported out of box.
  • No agents needed on monitored machines
  • Best implemented and most secure distributed testing, monitoring of network islands have never been so easy and secure.
  • Everything included, no dependency on external web server or
    database. Meaning fewer points of failures and less maintenance.
  • Less than 10 minutes from installation to start of monitoring.
  • Making full use of multi-core CPU machines, easily scale from 2 to 2500 monitored hosts.
  • Memory and resource conservative, less than a 10 MB download, less than 20 MB running (base configuration).
  • Very flexible reporting system, making it as easy to generate reports for 1 or 100 monitored machines
  • Any customer can customize and write their own tests and actions using the _free_ development environment.
  • Best in industry support and a dedicated community of users.

2. Active Network Monitor
Active Network Monitor is a tool for the day-to-day monitoring of
computers in the network. Active Network Monitor runs under Windows
NT/2000/XP and allows Systems Administrators to gather information from
all the computers (even from the Windows 9x/Me computers) in the
network without installing server-side applications on these computers.
Active Network Monitor provides the powerful technology of storing and
comparing received data. Administrators can make "snapshots" of the
systems for future comparison and notation of changes.

Active Network Monitor has a flexible plug-in based architecture that
allows you to plug in necessary modules on demand. Each module
(plug-in) performs a task and displays retrieved information in its own
window. Active Network Monitor ships with a predefined, constantly
growing list of plug-ins, including plug-ins for monitoring services,
devices, installed applications, disks, shared resources, hardware
resources (IRQs, I/O, DMA and Memory), users, local groups, global
groups and so on. Moreover, the Security Patch Analyzer plug-in
performs security patch assessment for the following operating systems
and applications: Windows NT 4.0/2000/XP/Server 2003, IIS 4.0/5.0, SQL
Server 7.0/2000, MSDE 2000, MDAC 2.5-2.8, MSXML 2.6/3.0/4.0/5.0, IE
5.01 and later, Exchange 5.5/2000/2003, Windows Media Player 6.4 and
later, Microsoft Virtual Machine, DirectX 7.0 and later, Microsoft
Office, and so on.

With ANM you can:

  • Use the growing list of plug-ins for gathering important information from the remote computers.
  • Scan network computers by types (Server, Workstation, SQL Server, etc.).
  • Scan network computers by names (you can select computers either from
    the network tree or load a predefined list from the file).
  • View information immediately from a plug-in, rather than wait for a scan process of all your computers to be completed.
  • Save retrieved information into the project in the special folder or into the external file.
  • Load previously saved information from the project or from the external file.
  • Export retrieved information into the CSV or TXT file.
  • Compare two previously saved projects or external files using special simple to use Compare Wizard.
  • Save compare results to the external file.
  • Easily navigate through the compare results using special buttons.

5. NetLimiter
NetLimiter is an ultimate internet traffic control and monitoring tool
designed for Windows. You can use NetLimiter to set download/upload
transfer rate limits for applications or even single connection and
monitor their internet traffic.

Along with this unique feature, Netlimiter offers comprehensive set of
internet statistical tools. It includes real-time traffic measurement
and long-term per-application internet traffic statistics


  • Grants – Grant is a brand-new feature in NetLimiter 2. It could seem
    similar to limits, but it works differently. When you set grant for
    application or connection, then it means that you grant specified
    bandwidth for it. If other application/connections take too much
    bandwidth, then it is taken from them and is given to
    application/connection with granted bandwidth.
  • Network monitor – NetLimiter 2 shows list of all applications communicating over network it’s connections and transfer rates.
  • Personal firewall functionality – You can allow or deny certain applications to connect to or from any network or zone.
  • Zones – NetLimiter 2 monitors and controls traffic separately on three
    predefined zones – My Computer, Local Network and Internet. For
    example, you can limit the traffic rate of your browser downloading
    from the Internet and let it download from intranet at full speed.
    Later we will add tool for defining you cutom zones.
  • Filters – With filters you can define groups of connections or
    applications and then apply rules to them. You can for example set
    DL/UL limit only for a specific IP address range or for a group of two
    or more applications.
    Rule editor and scheduler – Rule editor helps you to create advanced
    rules. For example, you can create limit or firewall rule for a group
    of applications which is valid only in a given time interval (=you can
    schedule limits, grants and fw rules).
  • Network manager – Using Network manager you can assign networks present
    on you computer to NetLimiter zones. It’s also possible to add your own
  • Statistics – Similarly to NetLimiter 1.x stats, NetLimiter 2 stats
    module is intended for long-term measurement of internet traffic. This
    feature lets you to track your internet traffic history since you’ve
    installed NetLimiter 2. NetLimiter 2 is able to automatically export
    statistical data to disk.
  • Traffic chart – This feature is known from previous version of
    NetLimiter. Traffic chart shows application’s or connection’s real time
  • Remote administration – You can control and monitor other computers remotely from one place.
