Decent Monitoring Service

[frostmir]

Hi

May I ask what is the decent monitoring service in pfsense? I want to monitor the usage of my users per host (IP Address) if who has the top and lowest bandwidth in detail for every interface and also the traffic that was comming in and out on the WAN interface.

pfSense Version 2.2.6

Currently I have this running services in pfSense.
1. apinger
2. bsnmpd
3. dansguardian
4. dhcpd
5. dnsmasq
6. ipsec
7. ntpd
8. squid
9. sshd

Can I have a problem with the services if I install a specific traffic monitoring tool?

Thanks
