wireshark - How to know what bots of a website, if I have no root access to the hosting they will read?

Question

Recently I have problem with Open Graph checkers unable to detect Open Graph data?. It turns out that the bots from the checkers are unable to access data. However, since I have no root access to my shared hosting, I can't use wireshark to know the exact bots that connects to my hosting, therefore cannot ask the technician to help me.

So is there a way to know the bots? I really have no idea where to start. The site I want to know is https://developers.facebook.com/tools/debug/og/object/

Answer 1

You can see and identify all traffic to your website in the access logs generated by apache, nginx, iss, ...

Furthermore there are already a lot of tools out there which are able to parse and reflect the data in a human reabable format. e.g. awstats
