CloudLinux<\/strong> is one of the widely used Operating System nowadays due to the high-level stability and advanced server security it provides, which makes it the first preference for hosting providers, especially in a shared hosting environment.<\/p>\n\n\n\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\n\n\n

The kernel makes sure that all LVEs get a fair share of the server’s resources, and that no customer can use more than the limits set for that customer.<\/p>\n\n\n\n


Today 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\n\n\n

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

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

 ID     EP    PNO    TNO     SPEED      MEM         IO       IOPS<\/strong><\/p>\n\n\n\n

user1     0      3      3        5%                 137              4          1<\/p>\n\n\n\n

user2     0      2      2        1%            130              3          1<\/p>\n\n\n\n

user3      0      1      1        0%           15              0          0<\/p>\n\n\n\n

user4      0      1      1        0%           22              0          0<\/p>\n\n\n\n

lvetop fields:<\/strong><\/p>\n\n\n\n

ID        user name if LVE id matches user id in \/etc\/passwd, or LVE id<\/p>\n\n\n\n

EP       <\/strong> number of entry processes (concurrent scripts executed)<\/p>\n\n\n\n

PNO       <\/strong> number of processes within LVE<\/p>\n\n\n\n

TNO       <\/strong> number of threads within LVE<\/p>\n\n\n\n

CPU       <\/strong> CPU usage by LVE, relative to total CPU resources of the server<\/p>\n\n\n\n

MEM   <\/strong> Memory usage by LVE, in KB<\/p>\n\n\n\n

I\/O<\/strong>        I\/O usage<\/p>\n\n\n\n

IOPS  <\/strong> number of read\/write operations per second<\/p>\n\n\n\n

In this way, we can monitor and locate the account hitting the Entry Processes via command line.<\/p>\n\n\n\n

A GUI interface of this tool is present in WHM as well :<\/p>\n\n\n\n
