How to monitoring performance and latency of network

I know that we have a lot of tools to monitor the network, but what should I have to look for ? How can I cheek if everything is ok ?

VERY broad question.
At the very basic you want to ensure your  network devices are up. :)
Other items are:
Node Status
Interface Utilization
Traffic Type Utilization (Netflow or JFlow)
CPU and Memory Utilization
Traffic Logs
Interface / Circuit Status


The list goes on and on, depending on how thorough you want to be and the options available int the monitoring tool you use.

Yes, I know that it´s very broad question.
I only want to check if everything is working fine, not so much broadcast, traffic type utilization and interface utilization.

Please define "everything" which you think you should monitor. We will suggest a name which will have all of them for you.

I think, for now, the most important is the traffic/workstation and the latency of the network.

For "traffic" , mrtg/prtg or any rrd tool can do. (free)

Latency of network--> Any basic monitoring software with ping/fping test would do.  Please note latency happens due to poor link/physical issue and the way to generate alarms for that would be packet drops/loss/crc etc. Both nagios and zabbix can do it for free. But they are linux based. If you are a windows person, you need to get any paid software.

"workstation"---> you need to be very specific what you want to monitor in workstations.
