[user]
[pset_list]]
DESCRIPTION
prints the current time, the length of time the system has been up, the number of users logged on to the system, and the average number of
jobs in the run queue over the last 1, 5, and 15 minutes for the active processors.
is linked to and prints the same output as displaying a summary of the current activity on the system.
Options
and recognize the following options:
Print the current time, the length of time the system has been up,
and the number of users logged on to the system in the first line of the output. The average number of jobs in the core over
the last 1, 5, and 15 minutes for the active processors is also printed.
When used with the option, the load averages for the processor sets (psets) are calculated on a core basis.
Suppress the first line and the heading line.
This option should not be used with the option. This option assumes the use of the option to
Use long output.
This option assumes the use of the option to
Print the current time, the length of time the system has been up, and
the number of users logged on to the system in the first line of the output. The load averages over the last 1, 5, and 15
minutes for the processor sets (psets) given in the command line, pset_list, are displayed in the subsequent lines. If no
arguments are given, the load averages are displayed for all the psets in the system.
If pset id of an empty pset is given in the command line, a corresponding message will be displayed. If the kernel does not
have the pset capability, gives an error. The option cannot be used along with other options except
Use the short form of output for displaying terminal information.
The terminal name is abbreviated, and the login time and CPU times are suppressed.
Print only the first line describing the overall state of the system.
This is the default for the command.
Print a summary of the current activity on the system for each user.
This is the default for the command.
EXAMPLES
The command:
produces text resembling the following:
depending upon the current status of the system.
The command:
gives the load average of all the psets in the system. If 0, 94, 95, and 97 are existing psets in the system, the output will look like
the following:
The command:
gives output which looks like the following if 94 and 95 are valid pset ids:
The command:
gives the load average of the system, producing output resembling the following:
The command:
gives the load average of all the psets in the system. If 0 and 1 are psets in the system, the output will look like the following:
