network monitoring

[rajibchicago]

We have two data centers located in two different cities connected to our MPLS WAN. We would like to monitor connectivity between those two data centers constantly, to confirm 100% availability. Can some one recommend some application (open source or commercial)? thanks

There are a ton of options, so I'll mention a few from cheapest to most expensive.

IPSLA-

You can set this up to ping from one host to another. You can view the statistics and it will show how many pings have succeeded and how many have failed. This run in IOS.

Open source management program-

NAGIOS I believe can do it.

Solarwinds Network Performance Manager-

This is one is my favorite. It will graph latency times and loss. It will ever calculate device/site availability so you don't have to. Nice webUI as well.

Hope this helps.

Hi,

you can also consider (Whats UP Gold) to monitor statistics like delay , packet loss , availability.

Hi,

you can also use CACTI, its free but need a bit time and effort to get it implemented, works very well.

Here is the link, and some screen shots
