318 * System activity data files
320 * The rule is: "strict writing, read any", meaning that sar/sadc can
321 * only append data to a datafile whose format is strictly the same as that
322 * of current version (checking FORMAT_MAGIC is not enough), but sar/sadf
323 * can read data from different versions, providing that FORMAT_MAGIC value
324 * has not changed (note that we are talking here of data read from a file,
325 * not data that sar reads from sadc, in which case the "strict" rule applies).
327 * Format of system activity data files:
330 * | file_magic structure
334 * | file_header structure
338 * | file_activity structure | * sa_act_nr
342 * | record_header structure |
348 * | Statistics structure(s) | * <count>
354 * | Statistics structure(s)... |
358 * Note: For activities with varying number of items, a __nr_t value, giving
359 * the number of items, arrives before the statistics structures so that
360 * we know how many of them have to be read.
361 * NB: This value exists for all the activities even if they share the same
362 * count function (e.g. A_NET_DEV and A_NET_EDEV). Indeed, statistics are not
363 * read atomically and the number of items (e.g. network interfaces) may have
366 * If the record header's type is R_COMMENT then we find only a comment
367 * following the record_header structure.
368 * If the record_header's type is R_RESTART then we find only the number of CPU
369 * (of type __nr_t) of the machine following the record_header structure.

823 * Number of items on the system, as counted when the system is initialized.
824 * A negative value (-1) is the default value and indicates that this number
825 * has still not been calculated by the f_count() function.

828 * A positive value (>0) has either been calculated or is a constant.
832 * Number of sub-items on the system.
833 * @nr2 is in fact the second dimension of a matrix of items, the first
834 * one being @nr. @nr is the number of lines, and @nr2 the number of columns.
835 * A negative value (-1) is the default value and indicates that this number
836 * has still not been calculated by the f_count2() function.

839 * A positive value (>0) has either been calculated or is a constant.

846 * meaning that it has not been calculated).
850 * Maximum number of elements that sar can handle for this item.
851 * NB: The maximum number of elements that sar can handle for sub-items
856 * Number of items, as read and saved in corresponding buffer (@buf: See below).
857 * The value may be zero for a particular sample if no items have been found.
861 * Number of structures allocated in @buf[*]. This number should be greater
862 * than or equal to @nr[*].
867 * This is the size of the corresponding structure, as read from or written
868 * to a file, or read from or written by the data collector.
873 * This is the size of the corresponding structure as mapped into memory.
874 * @msize can be different from @fsize when data are read from or written to
875 * a data file from a different sysstat version.
879 * Optional flags for activity. This is eg. used when AO_MULTIPLE_OUTPUTS
881 * 0x0001 - 0x0080 : Multiple outputs (eg. AO_F_MEMORY, AO_F_SWAP...)
882 * 0x0100 - 0x8000 : If bit set then display complete header (hdr_line) for
883 * corresponding output
884 * 0x010000+ : Optional flags
886 unsigned int opt_flags;
888 * Buffers that will contain the statistics read. Its size is @nr * @nr2 * @size each.
890 * [0] and [1]: current/previous statistics values (used by sar).
891 * [2]: Used by sar to save first collected stats (used later to
896 * Bitmap for activities that need one. Such a bitmap is needed by activity
897 * if @bitmap is not NULL.
