    Release Notes: This releases adds monitoring of resource consumption for individual threads, improves color handling for overloaded resources, adds selections for multiple system resources like disks and logical volumes, implements handling of arrow keys, applies limitations for process accounting, supports more resources like CPUs, and adds more per-process counters related to memory consumption.

      Release Notes: An additional value is shown for the current frequency and the current scaling percentage of the CPU. Additional system-level counters are shown for the total number of threads that are running, sleeping interruptible, and sleeping uninterruptible. When the number of lines in a window is too small for the amount of system-level lines, the number of variable resources (like disks, interfaces, etc.) is limited automatically to be able to continue. The signal SIGUSR2 can be sent to atop to take one more sample and terminate (e.g. used to speed up suspend/hibernate). Support for the disk type 'mmcblk'.

        Release Notes: Disk I/O statistics are maintained on level of logical volume (LVM) and MD device. Log files are properly switched in case of suspend/hibernate. Layout of lines with system-level statistics can be redefined. Previous atop-versions are automatically activated for older log files.

          Release Notes: The screen interface has been redesigned completely with support for a variable number of columns depending on the window size. It is now possible to define your own output line with process-level statistics. A system-wide configuration file was introduced for atop and atopsar. Handling of log files was improved and additional counters are maintained.

            Release Notes: The atop command shows the number of running and sleeping (interruptible/non-interruptible) threads per process and shows the PPID per process. The command atopsar is now able to make summary reports and shows information about the top 3 most active processes per sample. In both commands, several bugs have been fixed.

              Release Notes: This release added colors and (on request) markers in the reports generated by the command atopsar to highlight critical resource consumption. Several major bugs were fixed in atop/atopsar, mainly for larger and busier systems.

                Release Notes: A new command, atopsar, has been added to generate detailed system activity reports (similar to the UNIX command sar) using the compressed logfiles as written by atop. These reports can also be generated for the current situation by specifying an interval for atopsar on the command line.

                  Release Notes: Unformatted output can be produced to do further processing via scripts. Steal-percentage and disk-counters are supported for virtual machines. The scripts for daily logging have been improved. More than 65535 processes can be logged per interval now. Standard disk I/O statistics per process will be shown (in Linux kernel 2.6.20 and higher).

                    Release Notes: A busy percentage is shown for each network-interface. Colors are used to indicate that a particular hardware resource has (almost) reached a critical busy percentage. The most critical resource is automatically determined to adapt the sorting order for active processes dynamically. Minor bugs were fixed.

                      Release Notes: This release added a new line with system-level counters related to processor-utilization (including load averages, context-switches, and interrupts). The effective line speed in bits per second was corrected for all network interfaces (division by 1000 instead of 1024). User IDs and group IDs are supported as numerical values now.
