Is there software that could show all network and network device problems?

Question

linux

Hello. Not so long ago I got a job in a company that is engaged in IT - outsourcing. For me, several organizations were identified in which all clients are on Windows 7. Is there any software that could show me all the problems of the network and network devices (including the conflict of network cards, poor line bandwidth between the server and the client, lack of Internet on any client, etc.)? The software is needed for Linux. I want to simplify my work for myself: I came to the office of clients, connected to their network, launched a quick test and immediately saw where there were problems on the network and where to go. It would also not be bad if the software could save data, build a network map, in general, immediately collect information to the maximum. So that the next time I connect to the network, I can see which computer is now offline. Read a lot about Nagios,
ps Clients have one-rank networks, sometimes the usual dir -300 acts as a server distributing the Internet.
pps I decided to use Linux for personal self-development, since I had never sat on it before, and in general, there is not much experience in administration. Just received my diploma this year.

Answer 1

The class of problems is too wide - the absence of a printer connected to the workplace does not always mean that the printer is not available via icmp, samba, web.
In general, you need to install a monitoring system, like zabix or nagios, either in your company or at a client on one of the servers, set up monitoring of the operation of servers, services, services and devices, or connect offices via vpn and monitor in one place on your site.
and it is better to fulfill client requests in general exclusively in the mail through any ticket system, then the workload of each support engineer and system administrator will be clearly visible

Answer 2

Once upon a time, Friendly Pinger and OCS Inventory were popular for such purposes (network analysis and visualization) . The projects are now abandoned.
But there are also "live" analogues, if you search, for example Net Viewer or LanState , I'm sure you can find more.
For monitoring, slightly different tools are used, in fact, various monitoring systems , which include nagios.

A little offtopic, if you will.
How tasty is Linux Mint compared to Ubuntu?
I myself use ArchLinux, but I transferred the girl from Windows to Ubuntu (I chose the most convenient one). She adapted and is happy, but Ubuntu itself, let's say, is going in the wrong direction (errors, interface congestion, and the like).
