Release Notes: A new metric has been added to sar network devices statistics, giving the utilization percentage of the network interface cards. Several bugs have been fixed all around.
Release Notes: Virtual devices are no longer taken into account in sar -b results. iostat can now display target device information when a symbolic link is specified as a parameter. The option --disable-stripping has been added to the configure script. A Serbian translation has been added.
Release Notes: sadf has been modified to make it easier to add new report formats. The option "-P ON" has been added to mpstat, which tells mpstat to display stats only for online CPUs. pidstat displayed null statistics for processes that had terminated; this is now fixed.
Release Notes: Power management statistics have been added to sar. This release no longer truncates the interval of time to 32 bits, as this may cause some problems when displaying average values statistics on machines with hundreds of CPUs. A small bug in sar where it didn't parse arguments properly when some options were entered in a specific order has been fixed.
Release Notes: The option -h has been added to pidstat. This option is used to display all activities horizontally on a single line. A bug has been fixed in pidstat: When pidstat was used to monitor a process and all its threads (with pidstat's option -t), it could display weird values if the thread group leader terminated. mpstat now displays stats for all interrupts, including NMI, LOC, etc.
Release Notes: sar can now collect and display all CPU fields with its new option "-u ALL". mpstat can now display per-CPU interrupts statistics. mpstat now uses a separate option ("-I SUM") to display the total number of interrupts for each processor. NFS v4 support was added to "sar -n NFS(D)".
Release Notes: Iostat displays read and write operations per second in the NFS report. Sadc now retries to write its buffers when the write() call has been interrupted by a signal. The -h option has been added to sadf: used with the -d or -D options, it indicates that all activities should be displayed horizontally on a single line of data. Sadf -d and sadf -D now display the list of fields for easier data reading. NLS has been updated, adding a Chinese (Simplified) translation.
Release Notes: System activity data files have extra header data that enables you to identify which version of sysstat created them. Machine architecture is displayed in the reports header. The number of processors was not properly calculated on machines where a directory named cpuidle was present in the /sys/devices/system/cpu directory [Gentoo bug# 207886]. __CPU_SETSIZE definition from sched.h is used instead of a static definition for the maximum number of CPUs (NR_CPUS). Error messages displayed by sysstat's commands have been improved. NLS has been updated, adding a Finnish translation.
Release Notes: This version takes account of all memory zone types when calculating pgscank, pgscand, and pgsteal displayed by sar -B. An XML Schema was added. NLS was updated, adding Dutch, Brazilian Portuguese, Vietnamese, and Kirghiz translations.
Release Notes: The option -w was added to pidstat (pidstat can now display task switching activity). A memory leak that was triggered when reading stats for threads has been fixed in pidstat. A bug where device names were incorrectly displayed by sar -d has been fixed.
