<qt><i>Technical information: </i>This is an approximation of the Private memory usage, calculated as VmRSS - Shared, from /proc/*/statm. This tends to underestimate the true Private memory usage of a process (by not including i/o backed memory pages), but is the best estimation that is fast to determine. This is sometimes known as URSS (Unique Resident Set Size). For an individual process, see "Detailed Memory Information" for a more accurate, but slower, calculation of the true Private memory usage.
The CPU usage of a process and all of its threads.
<qt>The total system and user time that a process and all of its threads have been running on the CPU for. This can be greater than the wall clock time if the process has been across multiple CPU cores.
<qt><i>Technical information: </i>This is an approximation of the Shared memory, called SHR in top. It is the number of pages that are backed by a file (see kernel Documentation/filesystems/proc.txt). For an individual process, see "Detailed Memory Information" for a more accurate, but slower, calculation of the true Shared memory usage.
<qt><i>Technical information: </i>The underlying value (clock ticks since system boot) is retrieved from /proc/[pid]/stat
<qt><i>Technical information: </i>The flag is retrieved from /proc/[pid]/status
<qt><i>Technical information: </i>This is from /proc/*/cmdline
<qt><i>Technical information: </i>This is the amount of memory used by the Xorg process for images for this process. This is memory used in addition to Memory and Shared Memory.<br><i>Technical information: </i>This only counts the pixmap memory, and does not include resource memory used by fonts, cursors, glyphsets etc. See the <code>xrestop</code> program for a more detailed breakdown.
<qt><i>Technical information: </i>For each X11 window, the X11 property _NET_WM_PID is used to map the window to a PID. If a process' windows are not shown, then that application incorrectly is not setting _NET_WM_PID.
<qt><i>Technical information: </i>This is the Process ID. A multi-threaded application is treated a single process, with all threads sharing the same PID. The CPU usage etc will be the total, accumulated, CPU usage of all the threads.
<qt>This column shows the IO statistics for each process. The tooltip provides the following information:<br><table><tr><td>Characters Read</td><td>The number of bytes which this task has caused to be read from storage. This is simply the sum of bytes which this process passed to read() and pread(). It includes things like tty IO and it is unaffected by whether or not actual physical disk IO was required (the read might have been satisfied from pagecache).</td></tr><tr><td>Characters Written</td><td>The number of bytes which this task has caused, or shall cause to be written to disk. Similar caveats apply here as with Characters Read.</td></tr><tr><td>Read Syscalls</td><td>The number of read I/O operations, i.e. syscalls like read() and pread().</td></tr><tr><td>Write Syscalls</td><td>The number of write I/O operations, i.e. syscalls like write() and pwrite().</td></tr><tr><td>Actual Bytes Read</td><td>The number of bytes which this process really did cause to be fetched from the storage layer. Done at the submit_bio() level, so it is accurate for block-backed filesystems. This may not give sensible values for NFS and CIFS filesystems.</td></tr><tr><td>Actual Bytes Written</td><td>Attempt to count the number of bytes which this process caused to be sent to the storage layer. This is done at page-dirtying time.</td></table><p>The number in brackets shows the rate at which each value is changing, determined from taking the difference between the previous value and the new value, and dividing by the update interval.<p><i>Technical information: </i>This data is collected from /proc/*/io and is documented further in Documentation/accounting and Documentation/filesystems/proc.txt in the kernel source.
<qt><i>Technical information: </i>This shows Linux Control Group (cgroup) membership, retrieved from /proc/[pid]/cgroup. Control groups are used by Systemd and containers for limiting process group's usage of resources and to monitor them.
<qt><i>Technical information: </i>This shows Mandatory Access Control (SELinux or AppArmor) context, retrieved from /proc/[pid]/attr/current.
<i>Technical information:</i> This is often referred to as "Proportional Set Size" and is the closest approximation of the real amount of total memory used by a process. Note that the number of applications sharing shared memory is determined per shared memory section and thus can vary per memory section.
