How to check ddos attack?

Not really an i-MSCP support question, so I moved the thread.

What do you mean, how to check for a ddos attack? This should normally be handled by a firewall infront of your i-MSCP server. There is many different kinds of ddos attacks. SYN flooding is probably the most common one.
Please explain a bit more.

How to check logs on i-mscp?

You'll have to check the system logs to find proof of a ddos attack. That is not logged within i-MSCP.
Check logs files in:
/var/log/

install fail2ban

install fail2ban

Doesn't quite protect again a DDOS attack

But you could use it to protect again brute force attempts and exploit scanning, just make some custom filters =).

Hello

mod_evasive and/or Fail2ban

Just my two cents...

mod_evasive if you can configure it properly. Else you'll get more trouble then gain.

Can't I check the i-mscp to see if I get attacked or not?

This has nothing to do with i-MSCP. look in your logs
