Simple Network Monitor + Alerter?

We use Solarwinds at the moment and have reached our limit.

It's been a great tool but it's stupidly overpriced for what we need.

Looking for a tool that can monitor SNMP on switches, but also one that will simply ping devices and log response times/packet loss, and email alerts if a node goes offline.

Any ideas? I've googled all day and they all seem bloated and expensive for what we need!
 
Tried spiceworks? From what I remember about it, its free but ad supported

I tried it but it's not really what I'm after.

I just want something simple, where I can specify a list of IPs (not a range) and it tells me if they go down whilst logging the response time history :(

Might just make one myself :P
 
How many sensors do you want? You can get 30 sensors of PRTG free if you put their logo on a web page and send them an e-mail (scroll to the bottom of the page). We're just rolling out a 1000 sensor license for PRTG.
 
Cacti is another one that you could try, windows based and previously we used it for server and switch basic snmp monitoring. Not sure if the have updates it recently though
 
PRTG - it is costed, but I think once you use it and look at the pricing you'll agree it's worth while, it's pennies compared to solarwinds. We us both, we really like solarwinds but its pricing (per volume) is crazy especially on unix hosts.
 
We are currently using PRTG, quite a bit you can do/view, a lot of fine tuning though otherwise you will have false positives all over the place, many times we have had probes going that are reporting down yet the device was up and reachable. Can be a bit resource hungry in a browser aswel but has lots of potential.


I have used Whatsup gold before, I quite liked this one when we were using it!

Given i work in the monitoring industry, ive got a good handle on the market -the majority of the aforementioned are Linux based (Nagios forks such as Zabbix, Centreon, etc) and then OpenNMS, Cacti, etc are all Linux based too so you'll need a degree of Linux knowledge to run them.

The main non-Linux monitoring tools are really mentioned above; Solarwinds, WhatsUpGold, GFI, PRTG, Hyperic, etc however you'll probably have to pay for all of these also unfortunately.
 
We use Nagios (30000 services monitored, cant rememberthe node number) and Solarwinds (500 odd nodes) and to be honest it's close between them. Solarwinds has a lot of features that Nagios doesn't, or doesn't have without a lot of time and effort put into it. Nagios however is flexible and cheaper and with time put into it it's an excellent product (providing you have the skills internally to manage it and troubleshoot). For 150 nodes it's a tough call and it would depend on -

- Features you want
- Cost difference, factoring in needed support on Nagios
- Time you can sync into them

If time is an issue I'd stump up for Solarwinds, if not then Nagios
