Network analysis is the process of identifying and remediating the processes and systems within a network, including performance, connectivity and security. The process is performed through the use of tools developed for monitoring and analyzing network activity. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, Critical Path Analysis and PERT (Program Evaluation & Review Technique).

What makes NetCrunch network monitoring system unique?
There's a multitude of different network monitoring solutions out there, and you're probably wondering what makes NetCrunch so special.

  • It's completely agentless, but does let you create an agent, if you desire.
  • It offers powerful scalability on a single machine and requires only 4GB of RAM and 4 cores, which can be on a VM.
  • It's rule-based: it has monitoring packs, which are sets of rules for alerts. These can be applied by policy to any number grouping of nodes. This makes monitoring larger networks a breeze.
  • It has a pending alerts view, which shows you all the current problems that you have in your network instead of making you dig through the event log.
  • It's great at presenting live data. Your data can be shown on dashboards, live widgets or on custom views. On top of that, it's optimised for a multi-screen NOC room setting.
  • It supports all major operating systems and SNMP. There's also an extension protocol, that lets you write your own scripts and fit data in.
  • It comes with an embedded database so there's no requirement for additional administration or licensing.
  • There's no limit on a size or length of time to keep your performance data.
  • It runs on Windows and is very stable. Some of our clients are running version 5, which is over 7 years old!
  • It has simple, node-based licensing - just count the number of nodes you have. There's no limit on the number of elements, counters or sensors.

Hi Justin,

Not directly from Experts Exchange (as far as I know), but if you have a video download tool that works with youtube, all of our videos are also on youtube, in the "Paessler AG" channel.

If you'd like to learn PRTG using the videos, be sure to check out our free eLearning site, which has a combination of videos, manual pages and knowledge base articles in a sensible order.
