Monitor Real time resource usage in CloudLinux<\/strong><\/span><\/h4>\n

\"Monitor\"<\/p>\n

CloudLinux<\/strong><\/a>\u00a0OS is the leading platform for multitenancy. It improves server stability, density, and security by isolating each tenant and giving them allocated server resources. This creates an environment that feels more like a virtual server than a shared hosting account. By doing so, CloudLinux OS reduces operating costs and churn rates, and increases profitability. Let\u2019s see how to\u00a0Monitor Real time resource usage in CloudLinux.<\/p>\n

LVE (Lightweight Virtual Environment)<\/strong> is a kernel level technology developed by the CloudLinux team. It is lightweight and transparent. The goal of LVE is to make sure that no single website can bring down your web server.<\/p>\n

The kernel makes sure that all LVEs get fair share of the server\u2019s resources, and that no customer can use more than the limits set for that customer.
\n<\/span>
\nToday we can limit CPU, Memory (virtual and physical), IO, number of processes as well as the number of entry processes (concurrent connections to apache) on user specific.<\/p>\n

One of the best way to monitor current usage of users is \u201clvetop<\/strong>\u201d , which is similar to the \u2018top\u2019 tool we are familiar with .<\/p>\n

It will show you CPU, Memory , Entry Processes and other usage for a particular account in real time, as below :<\/p>\n
