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.

• 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

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,
