I can deploy a Zabbix Server to monitor your entire network
Actually i manage a Monitor Server with more than 5.000 network devices, servers, diskstations etc
Monitoring, by SNMP we can see all the network health in a simple map or dashboard
With this you should be able to monitor, Ping, interfaces, traffic, proceses, CPU usage, diskspace ... all you need
Its the most professional and robust option you can find
