I want to install a tool for bandwidth monitoring of users in entire network suggest me some tools
6 Spice ups
what does your network look like, do you have managed switches with SNMP? What’s your budget?
Off the cuff:
Spiceworks network monitor
Observium
SolarWinds
PRTG
NetCrunch
Cacti
All have differing levels of complexity, cost, and functionality.

Network is large but the organizatiom want me to suggest a tool that can monitor bandwidth consumption on each and every user there is a lan and wlan in that network, its just for the internal users not extenal,actually there is a conference room and meetings are conducted there, but sometimes there is low internet speed issue during meetings, that want me to suggest a tool that can tell that which ip is consuming the most of the bandwidth and to stop that user from using further bandwidth and also trace that user, kindly suggest me the best tool for that purpose thanks in advance
That’s a tough requirement. Most tools only track down to the MAC address. However, if you can associate a device to a specific user then this should be okay. Many of those tools would work, but it really comes down to. The reporting capabilities of your edge or core networking device. Many tools require NetFlow, and if your firewall or core switch can support that then youre options are thinned.
Thanks for the mention, Captain Frostbyte!
Yes, NetCrunch will do it for you pretty much out of the box. Complete netflow/bandwidth monitoring is available and on top of that NetCurnch makes automatic layer-2 maps which show you bandwidth and utilization in real-time.
@AdRem_Software
Also have you considered SFLow (aka netflow, jflow) this can be installed into a lot of these monitoring tools (I know PRTG Supports it)
And this should be able to break down the actual traffic into types/ports so you can track down exactly what’s causing it 
We used this to track down a person who was streaming Youtube on a shared device at lunch time “While noone was looking” 
On that ^ , NetCrunch monitors IPFix, NetFlow (v5 & v9), sFlow, JFlow, netStream, cFlow, AppFlow, rFlow and Cisco NBAR as well. That should get you covered from every angle.
