Using esxtop or resxtop in Interactive Mode
By default, resxtop and esxtop run in interactive mode. Interactive mode displays statistics in different
panels.
A help menu is available for each panel.
Interactive Mode Command-Line Options
You can use various command-line options with esxtop and resxtop in interactive mode.
Table 8‑2. Interactive Mode Command-Line Options
Option Description
h
Prints help for resxtop (or esxtop) command-line options.
v
Prints resxtop (or esxtop) version number.
s
Calls resxtop (or esxtop) in secure mode. In secure mode, the -d command, which specifies delay
between updates, is disabled.
d
Specifies the delay between updates. The default is five seconds. The minimum is two seconds.
Change this with the interactive command s. If you specify a delay of less than two seconds, the
delay is set to two seconds.
n
Number of iterations. Updates the display n times and exits. Default value is 10000.
server
The name of the remote server host to connect to (required for resxtop only).
vihost
If you connect indirectly (through vCenter Server), this option should contain the name of the ESXi
host you connect to. If you connect directly to the ESXi host, this option is not used. Note that the
host name needs to be the same as what is displayed in the vSphere Web Client.
portnumber
The port number to connect to on the remote server. The default port is 443, and unless this is
changed on the server, this option is not needed. (resxtop only)
username
The user name to be authenticated when connecting to the remote host. The remote server prompts
you for a password, as well (resxtop only).
a
Show all statistics. This option overrides configuration file setups and shows all statistics. The
configuration file can be the default ~/.esxtop50rc configuration file or a user-defined configuration
file.
c filename Load a user-defined configuration file. If the -c option is not used, the default configuration filename is
~/.esxtop50rc. Create your own configuration file, specifying a different filename, using the W single-
key interactive command.
Common Statistics Description
Several statistics appear on the different panels while resxtop (or esxtop) is running in interactive mode.
These statistics are common across all four panels.
The Uptime line, found at the top of each of the four resxtop (or esxtop) panels, displays the current
time, time since last reboot, number of currently running worlds and load averages. A world is an ESXi
VMkernel schedulable entity, similar to a process or thread in other operating systems.
