Are you saying that the private agent installed on a Windows or Linux computer is actually doing the SNMP monitoring? This is a problem for us, because we only permit SNMP queries from specific hosts, namely our Macintosh-based NMS and from Anturis. We don't enable general SNMP access from hosts on our LAN to our network devices, because the network devices are on a separate Management VLAN, which is a standard security practice.
