Second to last day on the Programming with C# using Microsoft ASP.NET4.0 course.

Next week I move onto the next course.  More on that later.


Another challenging day here at New Horizons Waltham.

I just want to give a quick shout out to the people who support us students here.  The mentors here at New Horizon are very knowledgeable and always willing to assist us.

Things are starting to sink in a bit and understanding is coming easier now.  A lot of studying... following this course.  I'll redo the labs, study the courseware more and ensure I understand everything.

Network Monitoring (Part Two)

Yesterday I spoke about network devices...  How they communicate what state the different parts of their functions are in.  I spoke about how these device communicate their messages over the network.  Most devices by default have SNMP turned on.  This means that if you have a network with 100 computers, 15 printer and 10 servers, ALL these devices are sending out quick small broadcast messages on the network everytime one of them have a message of state change or a problem.  Imagine the number of messages being generated not being sent to any one device.  How do you know what messages are important?  How can these messages be captured in one place?  How can meaningful information be derived from all this traffic?

Well the answer to all these questions comes in the form of an SNMP Manager.  An SNMP Manager is merely a service which listens on the network or receives all the messages and writes the messages into a database which can indexed and referred to in any number of ways.  This SNMP Mangaer comes in many different forms and is made by many different companies.  I have spent time evaluating this software and would like to share my experiences with one software that I found very stable, easy to use and very very flexible.

The software is called OpManager made by ManageEngine.

Below is a link to their software information:

Manage Engine - OpManager

In the coming days I will share with you my experiences with this software, how it works and what I used it for.

Todays Reader Challenge -  I am interested in your thoughts, experiences and ideas on the topic of SNMP.

Please put a comment in describing whether you have used SNMP Managers, what your experiences are with them or if you find the topic interesting.
