Previous pageReturn to chapter overviewNext page

lveps tool shows information about running LVEs, processes and threads belonging to them, CPU/memory/IO usage consumed by LVEs and their individual processes/threads. LVE is only reported if it is considered active (at least one thread belongs to that LVE or was running during measurement in dynamic mode).

 

Usage: lveps [-p] [-n] [-o <fmt1:width1,...>] [-d] [-c <time>] [-s <style>] [-t] [-h]

 

Options:

      -p to print per-process/per-thread statistics

      -n to print LVE ID istead of username

      -o to use formatted output (fmt=id,ep,pid,tid,cpu,mem,io)

      -d to show dynamic cpu usage instead of total cpu usage

      -c to calculate average cpu usage for <time> seconds (used with -d)

      -r to run under realtime priority for more accuracy (needs privileges)

      -s to sort LVEs in output (cpu, process, thread, mem, io)

      -t to run in the top-mode

      -h to print this brief help message

 

Command like lveps -p will display processes running inside 'active' LVEs.

 

CPU

The number of seconds LVE/process/thread has been running (each CPU/core is counted separately), or the average CPU load (100% is all CPU resources) if used with -d.

MEM

The number of megabytes of resident memory in use by LVE/process/thread (shared memory is not included).

IO

The number of kilobytes read and written in sum by LVE, or kb/sec if used with -d.

ID

LVE ID or username.

EP

The number of entry processes inside  LVE.

COM

Command name for this process.

PID

PID of the process.

PNO

The number of processes belonging to the LVE.

TID

TID of the thread.

TNO

The number of threads belonging to the LVE.

DO

The number of disk operations belonging to the LVE from the time it was created.

DT

Total amount of disk transfer in megabytes from LVE creation time.

IOPS

The number of I/O operations per second
