Table 7‑2. Interactive Mode Command-Line Options (Continued)
Option Description
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.
Below that the load averages over the past one, five, and fifteen minutes appear. Load averages take into
account both running and ready-to-run worlds. A load average of 1.00 means that there is full utilization of
all physical CPUs. A load average of 2.00 means that the ESXi system might need twice as many physical
CPUs as are currently available. Similarly, a load average of 0.50 means that the physical CPUs on the ESXi
system are half utilized.
Statistics Columns and Order Pages
You can define the order of fields displayed in interactive mode.
If you press f, F, o, or O, the system displays a page that specifies the field order on the top line and short
descriptions of the field contents. If the letter in the field string corresponding to a field is uppercase, the
field is displayed. An asterisk in front of the field description indicates whether a field is displayed.
The order of the fields corresponds to the order of the letters in the string.
From the Field Select panel, you can:
n
Toggle the display of a field by pressing the corresponding letter.
n
Move a field to the left by pressing the corresponding uppercase letter.
n
Move a field to the right by pressing the corresponding lowercase letter.
Interactive Mode Single-Key Commands
When running in interactive mode, resxtop (or esxtop) recognizes several single-key commands.
All interactive mode panels recognize the commands listed in the following table. The command to specify
the delay between updates is disabled if the s option is given on the command line. All sorting interactive
commands sort in descending order.
