* MFC 196254 - iostat: add a bit of space between tty in/out columnsGiorgos Keramidas2009-08-151-6/+6
| | | | | | | | | | | | The columns for tty input and output may bump against each other if the tty output needs more than 5 columns. Add a bit of space that pushes everything 1 column to the right, but also avoids the problem. Approved by: re (rwatson) Notes: svn path=/stable/8/; revision=196255

* Fix the device name spacing.Adrian Chadd2008-09-111-5/+5
| | | | | | | | | | | The old logic padded the device name out but assumed the unit number was one digit long; this fails for things like SATA devices which (for me) begin at ad10. Assemble the full device name in a temporary buffer and then calcluate padding based on that string. Notes: svn path=/head/; revision=182927

* Repeat iostat header after rows-3 instead of a hardcoded 20.Giorgos Keramidas2008-01-221-3/+71
| | | | | | | | | | | | | | | | Use ioctl() to get the window size in iostat(8), and force a new header to be prepended to the output every time the current window size changes. Change the number of lines before each header to `rows - 3' when the terminal is resized, so that the full terminal length can be used for output lines.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kernel: Change statistics to use the *uptime() timescale (ie: relative to boottime) rather than the UTC aligned timescale. This makes the device statistics code oblivious to clock steps. Change timestamps to bintime format, they are cheaper. Remove the "busy_count", and replace it with two counter fields: "start_count" and "end_count", which are updated in the down and up paths respectively. This removes the locking constraint on devstat. Add a timestamp argument to devstat_start_transaction(), this will normally be a timestamp set by the *_bio() function in bp->bio_t0. Use this field to calculate duration of I/O operations. Add two timestamp arguments to devstat_end_transaction(), one is the current time, a NULL pointer means "take timestamp yourself", the other is the timestamp of when this transaction started (see above). Change calculation of busy_time to operate on "the salami principle": Only when we are idle, which we can determine by the start+end counts being identical, do we update the "busy_from" field in the down path. In the up path we accumulate the timeslice in busy_time and update busy_from. Change the byte_* and num_* fields into two arrays: bytes[] and operations[]. Userland: Change the misleading "busy_time" name to be called "snap_time" and make the time long double since that is what most users need anyway, fill it using clock_gettime(CLOCK_MONOTONIC) to put it on the same timescale as the kernel fields. Change devstat_compute_etime() to operate on struct bintime. Remove the version 2 legacy interface: the change to bintime makes compatibility far too expensive. Fix a bug in systat's "vm" page where boot relative busy times would be bogus. Bump __FreeBSD_version to 500107 Review & Collaboration by: ken Notes: svn path=/head/; revision=112288

| | | | | | | | | | | | | | | | | | | originally written in January, 2000, but have been substantially updated. - No longer use hz/stathz and the CPU times in computing the TTY stats, but rather use etime, like the disk stats. - Clean up malloc/realloc failure tests. - Use a new integrated routine to fetch devstat information via sysctl or KVM. - Get rid of the X() macro for calculating CPU stats - Use rint() on the CPU state display to avoid truncation errors. (this requires libm) - Clean up flag usage somewhat. Reviewed by: bde Notes: svn path=/head/; revision=82168
