Tool Chest

The following is a collection of useful tools I’ve used I’m the past and have found useful.  Not all tools will be right for all organization and some have a pretty steep learning curve, but all can bee very useful in managing, designing, or troubleshooting computer networks.

Monitoring

For monitoring system status I’ve used both Nagios and WhatsUp Gold.

Nagios is a very flexible and powerful monitoring and alerting system.  Is for you if you have a little more time and a lot less money.  It is open source and the core system is free to download and use.  It does have a learning curve though so you may have to put some time into it.  Nagios does have a product for purchase that improves on the interface and management, making it more user friendly.

WhatsUp Gold a product you can purchase to do system status monitoring and alerting.  I’ve found it to be less flexible then Nagios, but it is a lot more user friendly and plug-n-play.  If you have some money to spend on a product for monitoring it is worth a look.
