Server overloaded

[Robertigno]

Hello!

I have a serious problem of exceptional use of resources for the server that hosts the site that I manage (the website is a blog done with Wordpress with an average of hits per day of 1500 visitors).

By controlling the statistics of the cPanel and the tool "CPU Usage and simultaneous connection" sees that is engaged above all the Physical Memory , Input processes and the Number of processes.
As regards the Physical Memory command always applicant that performs the server is

CMD: /usr/local/apache/bin/httpd -k start -DSSL
and
lsphp:/home/NAMESERVER/NAMEWEBSITE/index.php (but this less demanding)

You can to see a image here: [Removed - Please Attach Images Directly To The Thread]

I ask you who are experts.
From what could be caused according to you ?
At the end I find myself with two sites above this server that for good 40 minutes per day are down. The resources used are not even a few..Here you can see a summary[Removed - Please Attach Images Directly To The Thread]and here you can to see the features of server Enterprise[Removed URL]

Perhaps noticed something strange about accesses from bot? here: [Removed - Please Attach Images Directly To The Thread]


Thanks to you!

If bot is your issue..you can setup a test cookie challenge and most bots won't accept cookies and will fail

Hello,

You may also want to explore WordPress plugins to see if any might help to address the issue. Here's one I found:

Blackhole for Bad Bots

Thank you.

 

[Robertigno]

The problem of a surplus of resources of the server is always present,
once the site disappeared for two hours.
The site rests on Wordpress. Following your suggestions, I installed the plugin
Blackhole for Bad Bots (controls and stops the bot suspects) and WP Crontrol (monitors events WP-CRON).
For a long time before I installed Wordfence.
The instrument CPU and concurrent connection Usage reports no snapshots relating to hours down the site,
so I do not know what processes were active at that moment.
Accesses the daily average are 2 thousand accesses and on my server that I have in managing apart from this website there is another with irrelevant data access.

Server resources shared hosting at my disposal are:
Max Physical Memory 2 GB
Max Number of Processes 60
Max MySQL® Disk 235 GB
Max I/O 2048 KB/s
Max IOPS 200
Max Entry Processes 40

in recent days often appears the command
/usr/local/apache/bin/httpd -k start - DSSL
with memory use of 811 (then is increased compared to a week before)

Hello,

The following thread is also helpful for overall load troubleshooting:

That said, you may want to consider consulting with a system administrator if you are unable to pinpoint the source of the resource usage on the system. We provide a list of companies offering system administration services at:
