I use nagios, easy to use and plenty of online guides

Nagios all the way for me, I even have it using curl to check balances of certain accounts and get email warning and then critical alerts by phone

I've been using Zabbix for ages.

I used this one: http://old.amon.cx/

It is quite alright

I use PRTG, not cheap but there is a free version for small networks. Best monitor in my opinion.

Trying to find a web based server health / monitor, I;have munin installed with the web interface by it looks very outdated.

- Open source? if possible
- Web 2.0 / Modern
- Ajax if possible / Real time
- Easy to install / Minimal services to install

I've gone through pretty much everything mentioned in this thread: http://serverfault.com/questions/44/...r-your-servers

But nothing! You'd think by now someone would have created a good alternative to Munin!
