I need help figuring why my wordpress site crashes

I am having an issue with my vps server crashing due to overload. I was told by a developer that was attacked with DDoS. It affects my wordpress sites

I sent the info on to my host. However I am trying to get all the info I can on the issue.

Below is the report from the host. Please, have you seen this issue before, and what is your advise?

Hello Nigel,

While monitoring your vps I have found that there is high load on your vps which spike intermittently and I have found these scripts causing load:

Please check script xmlrpc.php with your website developer/vendor, check for any extra plugin install which is attracting high traffic on your vps. Please let us know if you have any additional questions or need further assistance.
