Release Notes: mpstat and sar didn't parse /proc/interrupts correctly when some CPUs had been disabled. This is now fixed. This release also fixes a bug in pidstat which caused confusion between PID and TID, resulting in erroneous statistics values being displayed. The iconfig script has been updated: Help for the --enable-compress-manpg parameter is now available, help for the --enable-install-cron parameter has been updated, and the parameter cron_interval has been added.
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.
Release Notes: The option -t has been added to pistat: pidstat can now display stats for every thread (TID) of a process. pidstat's option -T CHILD now reports global statistics for selected tasks and all their children (and not only for the children). A rare parallel make issue creating archive libsyscom.a was fixed [GENTOO bug #193208].
Release Notes: The pidstat command is now able to report CPU and page fault statistics for the child processes of a task. A security flaw in the sysstat startup script was fixed. The super*, dquot*, and rtsig* fields were removed from sar -v (since they were made obsolete in Linux kernels 2.6). The pty-nr field (number of pseudo-terminals) was added to sar -v. The tcp-tw field (number of sockets in TIME_WAIT state) was added to sar -n SOCK.
Release Notes: New virtual memory paging metrics have been added to sar (option -B). Options -x and -X have been removed from sar (use the pidstat(1) command instead.) NR_CPUS has been increased to 16384 so that sysstat can be used on very large systems. A bug in sadc.c where it was using a hardcoded 256 char buffer to store lines read from /proc/interrupts has been fixed. sar has been updated to avoid overflow when computing some average values.
Release Notes: The -d option was added to pidstat: this option reports I/O statistics for individual tasks. The -C option was added to sadc: this option enables the user to insert a timestamped comment in the binary data file. The -C option was added to sar: This option tells sar to display comments inserted in the binary data file by sadc. A bug that could happen while reading /proc/interrupts where IRQ numbers can now be 4 digits long in recent kernels was fixed. A possible buffer overflow in ioconf.c was fixed.
Release Notes: The addition of a new command "pidstat" aimed at displaying per-process statistics. The option -N has been added to iostat, which enables the user to query any device-mapper devices for their registered device name (useful for viewing LVM2 statistics). A small memory leak in the readp_uptime() function has been fixed. iostat -t now also takes into account the value of the environment variable S_TIME_FORMAT.
Release Notes: A bug that happened when sar tried to read a datafile created while a least one processor in a hotplug CPU system was disabled was fixed. Support for keeping sar logfiles for more than one month was improved. The new variable "conf_dir" now enables the user to specify a sysstat configuration directory (this variable is used by "configure"). The "--enable-compress-manpg" option was added to "configure" to enable the user to compress manual pages during installation. isag (Interactive System Activity Grapher) was improved.
Release Notes: Hotplug CPU support was improved. Now sysstat no longer assumes that CPU#0 can never be disabled. Various structures were realigned to save memory (and disk space). sar -n now displays network traffic in kilobytes instead of bytes. sysstat now compiles cleanly with gcc 4.0.2. NLS was updated, and a Danish translation was added.
Release Notes: Autoconf support has been added. iconfig (Interactive Configuration script) has been added. iconfig is a front-end to ./configure.
