Usage logs in cloudflare?

Hi all,
My website is being ddos’d.
Cloudflare under attack mode stops it enough for the site to remain standing.
However when I try to lower it (security level) the site is again overwhelmed.
I need to get logs of the attackers IPS so I can start banning them etc but my webhost are extremely difficult to get usage logs out of it.
Does cloudflare have a facility to show me similar reports? ip address, time, what they were doing like GET etc ?
Any help appreciated.
Best regards
