I have a small network, about 40 or so nodes that include switches, routers and firewalls.
I dont have a big budget and I dont want to get crazy with cost.
I also need something that is pretty straightforward and easy to deploy because I dont have a lot of people to work on it. The staff is also a bit inexperienced. When I say easy to deploy, I mean installation and configuration.
What would you recommend?
There are free ones out there, but I am not talking about those. I am talking about ones you purchase, like Orion.
Is Solarwinds Orion a good tool that fits my purposes?
Any other recommendations?
On the server you add the device by entering the IP address of the network device, the SNMP version (v1 or v2c will work with the commands above) and the SNMP community string. Then select what you want to monitor (e.g. interfaces, CPU, etc). Then go to the web interface of Orion and you should see your device. If you want added security you can use SNMPv3. I created a how-to for others it may help if you go that route.
The first screenshot is how you add the device.
