Hi there,
The Cloudflare Analytics are here to show the traffic that has been observed.
But I’m afraid they can’t help answering the “why” you’re seeing a spike.

You would need to check your traffic in more details, looking from pattern based on visitors location (IP/ASN/Country), URL accessed and also User Agent.
