I'm currently trialing Atera, and loving the platform so far - the only thing I'd suggest with network/monitoring and alerts is having the option to select numerous agents as the network monitor - for example with SNMP or generic, reason for this is, if your monitoring agent is offline; I've noticed with generic it doesn't show that your devices that are being monitored by the agent as offline. Perhaps have a round-robin method of monitoring, thus if a monitoring agent is offline but another is online it'll still monitor your network devices - but also, with that being said if a monitoring agent is offline if it's being used to monitor SNMP / generic, that should automatically see those devices as offline as well and alert you.
