Diagnosing intermittent network issues?

I recently inherited a site with a dozen SPF fiber lines ran out to dozens of various switches. The network keeps randomly going out altogether for 10-15 minutes, some wifi devices just stop being able to pull DHCP until they're rebooted, one switch simply can't pull DHCP at all but all static traffic works, just some weird random BS.

Anyone have some go-to tips to examine this traffic and see what's going on? My guess is a broadcast storm so I need to just sit at each end of the site and monitor wireshark, but I'm not too savvy in monitoring these things.

Any tools to help diagnose extremely odd network behavior before I just start yanking and recabling 11 acres of facility?
