Network Monitoring Software

controlcontrol Senior MemberMember Posts: 309
Can anyone share their experiences with any Network Monitoring software they have used in the real world. I'm interested in looking at Interface Utilization to see if the current links are being stretched Bandwidth wise.

Ideally free for commercial use - I've been looking at MRTG. Anyone used this? If I was using it to monitor core router interfaces, does it have any impact on router performance at all?

    Cacti is probably your best bet - free, unlimited devices and easy to set up even for a Linuxphobe like myself

    PRTG is also very good but only the first 10 devices are free

    MUTINY is another one,

    again only first 10 devices are free. but it has a very easy web based interface and even the paid version is not to bad.

    it uses SNMP (as most monitoring does) and this has minimal impact on performance. SNMP by its very nature is designed to have minim impact on performance, and in the real world even very heavy usage of it will not have any effect.

    Mutiny can provide at a glance usage, predefined usage alerts, and at a click hestorical data/trends.

    If you get good at it OpenNMS is a winner. Before Open, I used Nagios and Cacti.

    For a small network you can download a groundworks virtual appliance and just add devices it supports 50 for free with a bunch of options and a nice gui.

    Spiceworks is very complete for a small network, the most complete tool for asset tracking, SNMP monitoring, Bandwidth monitoring and ticketing.

    Zabbix. Best free nms I've ever used.

    Icinga and Cacti are what we use here at our shop.

    Nagios and Cacti are what I've used in the past and they both work very well

    SolarWinds Orion is my favorite one. The amount of features and information you can monitor with it is crazy.
  • chmodchmod Senior Member Member Posts: 360 ■■■□□□□□□□
    Is great but so expensive, just a few companies can afford their licensing to get all the features.

    Zenoss for the win!

    Cacti for free but once you use PRTG you'll see its worth the $$

    I was wondering if anyone was going to mention PRTG; I've been a fan if it for several years. It certainly doesn't try to do everything that that big programs do, but it is at a very good price point and has great functionality.
