How to find out information about a LXC (Linux container) CPU & Memory Usage

To find out information about the CPU and memory usage of a Linux container (LXC), you can use the lxc-info command with the -n option, followed by the name of the container. The syntax is as follows:

lxc-info -n container_name

This will display information about the container, including the CPU and memory usage.

For example, the output might look something like this:

Name:           container_name
State:          RUNNING
CPU use:        1.06 seconds
CPU usage:      0.00%
Memory use:     94.47 MB
Memory limit:   2.00 GB

In this example, the container is running and is using 1.06 seconds of CPU time and 94.47 MB of memory.

Alternatively, you can use the lxc-cgroup command with the -n option, followed by the name of the container, to display the CPU and memory usage of the container. The syntax is as follows:

lxc-cgroup -n container_name cpuacct.usage
lxc-cgroup -n container_name memory.usage_in_bytes

This will display the CPU usage in microseconds and the memory usage in bytes.

For example, the output might look something like this:

106000
99473920

You can use the lxc-cgroup command with the -n option, followed by the name of the container, to display the CPU and memory limits of the container. The syntax is as follows:

lxc-cgroup -n container_name cpuacct.usage_percpu
lxc-
