338 * System activity data files
340 * The rule is: "strict writing, read any", meaning that sar/sadc can
341 * only append data to a datafile whose format is strictly the same as that
342 * of current version (checking FORMAT_MAGIC is not enough), but sar/sadf
343 * can read data from different versions, providing that FORMAT_MAGIC value
344 * has not changed (note that we are talking here of data read from a file,
345 * not data that sar reads from sadc, in which case the "strict" rule applies).
347 * Format of system activity data files:
350 * | file_magic structure
354 * | file_header structure
358 * | file_activity structure | * sa_act_nr
362 * | record_header structure |
368 * | Statistics structure(s) | * <count>
374 * | Statistics structure(s)... |
378 * Note: For activities with varying number of items, a __nr_t value, giving
379 * the number of items, arrives before the statistics structures so that
380 * we know how many of them have to be read.
381 * NB: This value exists for all the activities even if they share the same
382 * count function (e.g. A_NET_DEV and A_NET_EDEV). Indeed, statistics are not
383 * read atomically and the number of items (e.g. network interfaces) may have
386 * If the record header's type is R_COMMENT then we find only a comment
387 * following the record_header structure.
388 * If the record_header's type is R_RESTART then we find only the number of CPU
389 * (of type __nr_t) of the machine following the record_header structure.
