Extensive CPU usage (over 400% at the graph)

[Vladimir]

Hello, I noticed huge CPU usage at the graph and when checked the log I saw a www-data user. Is this something normal?

@Vladimir check services, one may be down.

[Vladimir]

@robi All services seem to be green and working.

[robi]

can you tell which app it's coming from?

@Vladimir
I have 2 apps, both are WordPress unmanaged. The 1st one seems to be problematic.

Perhaps it's been hacked or something?

Do you have Wordfence installed?

It's a must-have for any WordPress site imho:

Have you checked the logs of the app to see what it's doing?

@robi Hello
the log seems ok to me.
I am using Cloudflare under attack mode + bot fight mode + advanced hardening techniques for WordPress. The log seems fine. I have performed a full Wordfence scan too and there were no problems.
I have disabled my multilingual plugin (translatepress) and the graph dropped a little - between 70-150%.

I have manually checked some of the files and the users + changed their passwords and enable login only for 1 IPs - the one in the office. Before, there were enabled several IP as some employees were logging from home.

Is this www-data user normal? Its CPU load dropped a little too.

@Vladimir Sounds like a popular site with lots of traffic.

Sounds like you found one reason to be the translation plugin.

You should be able to view the apache logs and monitor for errors, similarly for long DB calls which might make things wait, but then you'd notice site slowness from that too.
