Bandwidth monitor

Hello everyone, i hope you all started this year the best way.
I need your help to complete a task. I have a Ccr 1009-7G v6.49.7. I cannot upgrade because there is not enough memory, many filters and queues applied. We have 3 LANs in our network. I have to monitor all the traffic in the network, Lan and Internet. At the end of the day i need to generate a report for each IP and find out whith which host/internet it communicated. Also when the total WAN bandwidth reaches for example 80mbps i need to get a notification with email, or when a host is transferring more than 50mbps in LAN. This is more for security reasons. I hope you can suggest me the best and easy tool that works with mikrotik. I am trying prtg but in most cases netflowv9 does not work and i cannot add a sensor in each host. Also i see that in the total report the bandwidth is not specified by ip but by protocol. And i am not finding where i can see the report for a specific ip, except when i filter in the sensor settings, but i cannot tell my director to do this edit all the time since it is a little technical.

Thank you
