Traffic by category through the router

hello mikrotik developers
could develop an option that can identify the traffic by category (social network, xxx,etc) that runs through the router or capsman
with this tool we can pass a report to our managers
and could be integrated into the web service of mikrotik and thus show graphics and information

It is practically impossible to load such feature into typical 16MB storage on routerboards and there are already many external tools for traffic analysis.
If you need to create reports for your managers, find a netflow/ipfix/tzsp analyzer based on your required features and then configure your Mikrotik to forward netflow/ipfix/tzsp to your collector.
Personally, I am afraid you will have hard time to find any analyzer, which would categorize traffic this way. Keep in mind that most websites is now running over https so you cant analyze data and you depend on IP and DNS which is quite unreliable. Most analyzers which I saw were categorizing traffic by type (http / https / ftp / email / dns / unknown tcp / unknown udp / etc…) and/or country of origin.
In addition, it will have absolutely no result if people use vpn/proxy.

If you are talking about company and employees, much easier approach is to use productivity monitoring tools like ActivTrak / RescueTime etc… There are many, each with different features but usually it works the way that you install little piece of software on computer and it records usage of computer. (some are hidden, some require user to start/stop recording etc)
However, keep in mind that in any case, if you start spying on what employees are doing, it might be against legislation in your country. Especially if employees are not informed about collection of such data and did not give consent, they would have easy case in front of court. (that applies on both traffic analysis or installed monitoring tools)
You don’t need to explain yourself here - I am not an enemy and I do not judge you. It was just friendly reminder that there are such issues which can easily turn against employer.
