How do I troubleshoot high resource usage reported by CloudLinux?
In the event your service is hitting these limits you may see 500, 503, 508 errors or a general slow-down of your website as a result.
To confirm you can login to your cPanel service and goto the Resource Usage icon, this will show you your percentage utilisation of each resource type.
If you are using a considerable amount of Memory, CPU or diskIO it typically means a resource heavy website; this could simply be the result of an increasingly resource heavy website which needs a more powerful solution or it could be the result of some rogue code (such as a script plugin) which is acting out of sorts. Taking a look at any recently installed plugins by disabling them and re-enabling them one by one may shed some light on this scenario.
Other causes may be malicious users or bots flooding your website with hits; you can check this via cPanel using the Raw Acccess Logs, Latest Visitors and AWStats. These tools will tell you where they're coming from in terms of an IP, you can then use a GeoIP tool to check their origin - if they're from overseas locations you don't expect to receive connections from, you can use the cPanel IP Deny Manager to block them.
