Network Monitoring for MSP - looking for suggestions.

Hi,

We're looking to create a monitoring setup for a NOC-style service offering for SMB/Small enterprise customers (5-200 network devices).

In the optimal world, we'd be able to do this with a central monitoring server/servers in Azure/AWS, and a remote probe/proxy/poller at each customer. We do not have any physical hardware. If at all possible we'd like to avoid having S2S tunnels to each customer.

PRTG can do this, but sizing is a big issue here - as well as needing the core server on physical hardware.

LibreNMS looked promising at first, but the requirement for distributed pollers to have direct access to SQL/memcache etc. seems to prevent this sort of setup.

NetXMS seems to do it via proxy agents, but haven't found any documentation on whether the proxied SNMP etc. is encrypted between the core server and the agent. Not a big fan of cleartexting everything between customer sites and Azure/AWS. SNMPv3 may not be an option for all devices.

Anyone have experience with a similar setup, or have other insight on this?
