All releases of sysstat
Release Notes: mpstat now takes into account every interrupt per processor so that their number adds up to the number displayed for CPU "all". The systemd unit file could no longer be installed because a macro wasn't expanded in the configure script. This is now fixed.
Release Notes: sar, pidstat, and mpstat now stop and display their average statistics when they receive a SIGINT signal (crtl/c). pidstat now displays the task's UID for all tasks. The option -U has been added to pidstat; this option tells it to display the username of the task instead of its UID. When this option is followed by a user name, only tasks belonging to the specified user are displayed by pidstat.
Release Notes: Network and IPv4/IPv6 counters have changed to 64-bit format to keep in sync with recent kernels. A new option has been added to iostat to prevent it from displaying its first report with statistics since system boot. Several bugs have been fixed.
Release Notes: A new field has been added to sar -u and mpstat: %gnice (time spent running a niced guest). A new field has been added to sar -r: kbdirty (amount of memory waiting to get written back to disk). Support has been added for the systemd service manager. The sysstat init script has been updated to make it better conform to the LSB.
Release Notes: Option -[0-9]+ has been added to sar to show the data of that many days ago. iostat and sar have persistent device names support. A new option (-t) has been added to sadf: This option tells sadf to display the timestamps in the local time of the data file creator instead of UTC.
Release Notes: The options -g and -T have been added to iostat; these options enable the user to display statistics for groups of devices. sadc now overwrites its standard daily data file when this file is from a past month. The time format has been changed from HH-MM-SS to HH:MM:SS in the various reports displayed by sadf. A maxOccurs indicator for the timestamp element has been added in the XSD document. The option --enable-collect-all has been added to the configure script to tell sadc to collect all possible activities, including optional ones. A new translation file has been added for Croatian.
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: A new output format has been added to sadf: JSON (JavaScript Object Notation). Several bugs have been fixed in sadf XML output, DTD, and XSD documents. A random crash with iostat -N has been fixed.
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: A new option has been added to sar: it can now take a snapshot of all the USB devices currently plugged into the system. The option -h has been added to iostat to make the device utilization report easier to read with long device names. A bug has been fixed with cifsiostat that didn't count open files from the "Posix Open" column in the /proc/fs/cifs/Stats file. NLS has been updated: an Esperanto translation has been added.
