== OpenVZ specific ==
 
=== vzps ===
This utility program can be run on the Node just as the standard Linux ps. For information on the ps utility please consult the corresponding man page, vzps provides certain additional functionality related to monitoring separate Containers running on the Node.
 
The vzps utility has the following functionality added:
 
* The -E CT_ID command line switch can be used to show only the processes running inside the Container with the specified ID.
 
=== pvectl ===
 
pvectl - vzctl wrapper to manage OpenVZ containers - see "man pvectl"
 
=== vzctl ===
 
vzctl - utility to control an OpenVZ container - see "man vzctl"
 
=== vztop ===
This utility program can be run on the Node just as the standard Linux top . For information on the top utility please consult the corresponding man page, vztop provides certain additional functionality related to monitoring separate Containers running on the Node.
 
The vztop utility has the following functionality added:
 
* The -E CT_ID command line switch can be used to show only the processes running inside the Container with the ID specified. If -1 is specified as CT_ID, the processes of all running Containers are displayed.
* The e interactive command (the key pressed while top is running) can be used to show/hide the CTID column, which displays the Container where a particular process is running (0 stands for the Hardware Node itself).
* The E interactive command can be used to select another Container the processes of which are to be shown. If -1 is specified, the processes of all running Containers are displayed.

===USAGE===
== Debian Appliance Builder ==
pveversion [--verbose]


* without any argument shows the version of pve-manager, something like:
=== dab ===
:pve-manager/1.5/4660


* with -v argument it shows a list of programs versions related to pve, like:
See [[Debian Appliance Builder]]


:pve-manager: 1.5-7 (pve-manager/1.5/4660)

Simple host performance test.


(from man page)
Simple host performance test - see "man pveperf".


===USAGE===
Note: this command may require root privileges (or sudo) to run, otherwise you get an error after "HD SIZE" value, like: &lt;&lt;sh: /proc/sys/vm/drop_caches: Permission denied unable to open HD at /usr/bin/pveperf line 149.&gt;&gt;
:pveperf [PATH]


===DESCRIPTION===
==== Example output ====
:Tries to gather some CPU/Hardisk performance data on the hardisk mounted at PATH (/ is used as default)
<pre>
It dumps on the terminal:
CPU BOGOMIPS:     26341.80
REGEX/SECOND:      1554770
HD SIZE:          94.49 GB (/dev/mapper/pve-root)
BUFFERED READS:   49.83 MB/sec
AVERAGE SEEK TIME: 14.16 ms
FSYNCS/SECOND:    1060.47
DNS EXT:          314.58 ms
DNS INT:          236.94 ms (mypve.com)
</pre>


* CPU BOGOMIPS: bogomips sum of all CPUs
=== pvesubscription ===
* REGEX/SECOND: regular expressions per second (perl performance test), should be above 300000
* HD SIZE: harddisk size
* BUFFERED READS: simple HD read test. Modern HDs should reach at least 40 MB/sec
* AVERAGE SEEK TIME: tests average seek time. Fast SCSI HDs reach values < 8 milliseconds. Common IDE/SATA disks get values from 15 to 20 ms.
* FSYNCS/SECOND: value should be greater than 200 (you should enable "write back" cache mode on you RAID controller - needs a battery backed cache (BBWC)).
* DNS EXT: average time to resolve an external DNS name
* DNS INT: average time to resolve a local DNS name


Note: this command may require root privileges (or sudo) to run, otherwise you get an error after "HD SIZE" value, like:
For managing a node's subscription key - see "man pvesubscription"
<<sh: /proc/sys/vm/drop_caches: Permission denied
unable to open HD at /usr/bin/pveperf line 149.>>

Introduction

This page lists some important Proxmox VE 3x and Debian command line tools.

KVM specific

qm

To view a list of KVMs: 

qm list

      VMID NAME                 STATUS     MEM(MB)    BOOTDISK(GB) PID
       100 alpha001             running    2048               8.00 5858
       101 WINXP002             running    1024              32.00 6177
       102 Win2K                running    2048              32.00 113893
       105 axe002               running    16384            100.00 279613

To see how much memory your machine 101 has: 

qm config 101 | grep ^memory

memory: 2048

see "man qm" for further info

QEMU Emulator: User Documentation | Monitor Commands

OpenVZ specific

vzps

This utility program can be run on the Node just as the standard Linux ps. For information on the ps utility please consult the corresponding man page, vzps provides certain additional functionality related to monitoring separate Containers running on the Node.

The vzps utility has the following functionality added:

  • The -E CT_ID command line switch can be used to show only the processes running inside the Container with the specified ID.

pvectl

pvectl - vzctl wrapper to manage OpenVZ containers - see "man pvectl"

vzctl

vzctl - utility to control an OpenVZ container - see "man vzctl"

vztop

This utility program can be run on the Node just as the standard Linux top . For information on the top utility please consult the corresponding man page, vztop provides certain additional functionality related to monitoring separate Containers running on the Node.

The vztop utility has the following functionality added:

  • The -E CT_ID command line switch can be used to show only the processes running inside the Container with the ID specified. If -1 is specified as CT_ID, the processes of all running Containers are displayed.
  • The e interactive command (the key pressed while top is running) can be used to show/hide the CTID column, which displays the Container where a particular process is running (0 stands for the Hardware Node itself).
  • The E interactive command can be used to select another Container the processes of which are to be shown. If -1 is specified, the processes of all running Containers are displayed.

vztop - display top CPU processes
