When I go into Wordpress plugin, iThemes Security log.
I find many attempts to log in (I am the only user of this test site, with close to 0 content)
I see 5 php-fpm-7.0 process at 25 % cpu load each (Celeron J2900 quad core cpu). The site feels lees responsive.
So my question:
NR1 : What logs or command to use, to monitor this from OpenBSD command line.
NR2: Is modification of pf rulset, to implement something like fail2ban the way forward to free up system resources?
