Project Release Information
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.
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.
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.
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.
Several bugs have been fixed in sadf XML output, DTD, and XSD documents.
A random crash with iostat -N has been fixed.
The sysstat package contains the sar, sadf, iostat, nfsiostat, cifsiostat, mpstat, and pidstat commands for Linux. The sar command collects and reports system activity information. The statistics reported by sar concern I/O transfer rates, paging activity, process-related activites, interrupts, network activity, memory and swap space utilization, CPU utilization, kernel activities, and TTY statistics, among others. The sadf command may be used to display data collected by sar in various formats. The iostat command reports CPU statistics and I/O statistics for tty devices and disks. The pidstat command reports statistics for Linux processes. The mpstat command reports global and per-processor statistics. The nfsiostat command reports I/O statistics for network filesystems. The cifsiostat command reports I/O statistics for CIFS filesystems.
