Multiple Login Failure Attempts

How can I search for 10 failed logon attempts within a 5 minute timeframe?
I could try timechart, but a 24 hour period does not allow the interval to be as small as 5 mins. I could also "stats count by user", but this does not show any aspect of time.

Like this:

... | streamstats time_window=5m count(failed_logins) AS failed_logins BY user | where failed_logins >=10

@woodcock - Since he mentioned stats count by user I think he wants ten failed logins for a single user...

No I'm actually looking for all failed logins by users. >10 was the most important part. Thanks
