Data frame with the currently running processes.
ps(user = NULL, after = NULL, columns = NULL)Username, to filter the results to matching processes.
Start time (POSIXt), to filter the results to processes
that started after this.
Columns to include in the result. If NULL (the default),
then a default set of columns are returned, see below. The columns are
shown in the same order they are specified in columns, but each
column is included at most once. Use "*" to include all possible
columns, and prefix a column name with - to remove it.
Data frame, see columns below.
Columns shown by default, if columns is not given or NULL:
pid: Process ID.
ppid: Process ID of parent process.
name: Process name.
username: Name of the user (real uid on POSIX).
status: I.e. running, sleeping, etc.
user: User CPU time.
system: System CPU time.
rss: Resident set size, the amount of memory the process currently
uses. Does not include memory that is swapped out. It does include
shared libraries.
vms: Virtual memory size. All memory the process has access to.
created: Time stamp when the process was created.
ps_handle: ps_handle objects, in a list column.
Additional columns that can be requested via columns:
cmdline: Command line, in a single string, from ps_cmdline().
vcmdline: Like cmdline, but each command line argument in a
separate string.
cwd: Current working directory, from ps_cwd().
exe: Path of the executable of the process, from ps_exe().
num_fds: Number of open file descriptors, from ps_num_fds().
num_threads: Number of threads, from ps_num_threads().
cpu_children_user: See ps_cpu_times().
cpu_children_system: See ps_cpu_times().
terminal: Terminal device, from ps_terminal().
uid_real: Real user id, from ps_uids().
uid_effective: Effective user id, from ps_uids().
uid_saved: Saved user id, from ps_uids().
gid_real: Real group id, from ps_gids().
gid_effective: Effective group id, from ps_gids().
gid_saved: Saved group id, from ps_gids().
