Insufficient key column information for updating or refreshing

Control Groups provide for allocating resources (cpu, memory, network bandwidth, etc.) among installation-defined groups of processes.

They enable fine-grained control over allocating, denying, prioritizing, managing and monitoring those resources.

Output-width-override In 'Batch' mode, when used without an argument top will format output using the COLUMNS= and LINES= environment variables, if set.

Otherwise, width will be fixed at the maximum 512 columns.

See the 'c' interactive command for additional information.

Delay-time, where interval is represented as: (secs.tenths) Specifies the delay between screen updates, and overrides the corresponding value in one's personal configuration file or the startup default.

Without this command-line option a summation of all threads in each process is shown. This command-line option only and should you want to return to normal operation, it is not necessary to quit and restart top -- just issue any of these interactive commands: '=', 'u' or 'U'.

Later this can be changed with the 'H' interactive command. The 'p', 'u' and 'U' command-line options are mutually exclusive.

Fractional seconds are honored, but a negative number is not allowed.

With an argument, output width can be decreased or increased (up to 512) but the number of rows is considered unlimited.

In normal display mode, when used without an argument top will attempt to format output using the COLUMNS= and LINES= environment variables, if set.

See the 'S' interactive command for additional information regarding this mode.

User-filter-mode Display only processes with a user id or user name matching that given.
