Nothing will give you a complete inventory of what exists at a client for the simple reason that not everything is always present and switched on.
You either take a snapshot and forget devices which are not present, or you scan on a regular basis and accept that dhcp enabled machines are going to screw up your results as they change ips.
LT shows three different things
- Hosts it has detected and installed an agent on
- network devices which have responded to snmp
- Network devices which have responded to ping
There isn't an integrated report which overlaps these three types of devices into a subnet map, no.
LT does have a problem at the moment of not expiring network devices and not removing network devices whose IPs correspond to active PCs. So the list of machines which have responded to ping really doesn't serve much purpose.
Servers which have snmp enabled will appear duplicated as they are both hosts and snmp devices.
I'm not sure what you mean by
LabTech's network scans do try a bit to figure out what various devices are, but what little information they gather basically just gets thrown away,
What do you want, a network capture? LT doesn't try to profile nodes using port response fingerprinting, no, but then what for? Its a management tool, not a scanner. What would it do knowing that 192.168.1.206 happens to be running apache but isn't manageable? It will get added as an unknown device type.. i.e ping response.
You *can* get LT to run your favourite network port scanner and to upload the results to your server where you can spend happy hours reading about all the devices on your clients networks.
