wmmon/CHANGES:
Updated for 1.2b1.
wmmon/Makefile:
Added debug build with -g3; default build with -O3. Note:
This makefile isn't perfect. You must "make clean" when switching
between "make" and "make debug" otherwise objects won't compile.
I'm sure it's a simple dependency issue, but I am not an expert with
Makefiles. I intend to fix this, but it's a low priority.
wmmon/wmmon/wmmon.c:
Updated changelog. Added #define HISTORY_ENTRIES to replace hardcoded
values.
DrawStats_io():
Removed static variable global_io_scale. Replaced with a local
variable. This should improve graphing - scale was growing, but
never shrinking, meaning as time passed, graphed values were
downscaled and not displayed.
Fixed rounding errors caused by use of integer types which were
causing very small values not to appear on graph. Added code to
round very low values up, so they will appear on meter and graph.
We are making a reasonable compromise between readability and
accuracy. Side effect is that small peaks (greater than 0 but less
than our rounded-up tiny values) will actually appear as dips
instead of peaks. I feel this is acceptable, since it still conveys
an impression of "jitter" to the user. Fixing this would have
involved further modifying the data before we graph it, which would
defeat the purpose of improving accuracy.
Tweaked load bar scaling algorithm for reabality and sensitivity.
update_stat_io():
Added a "stale" timeout for static long maxdiskio (determines
scaling of load bar). New behaviour is that every couple of minutes
we discard our saved peak value and resample. This prevents an
anomalously huge I/O spike from making more typical values fail to
trigger the load bar for the rest of the app's lifetime. Side
effect will be that every couple of minutes, we will get an
anomalous spike in the load bar as it recalibrates. This anomaly
only affects the bar, not the graph.
getWidth():
Fixed integer rounding issue similar to that in DrawStats_io().
Added similar rounding code to round up very small values so we
don't have the illusion of an idle system following a huge spike.

Version Description
|
|
--------------------------------------------------------------
|
|
1.2b1 - Released 20120325
|
|
- I/O monitor - updated to use /proc/diskstats instead
|
|
of obsolete /proc/stat interface, which is no longer
|
|
present in post 2.6 kernels. TODO: The non-/proc based
|
|
solutions used in the various BSD ports trees should
|
|
be incorporated into mainline version.
|
|
- I/O monitor - Fixed scaling issues with graph caused
|
|
by improper use of static data. The graph would
|
|
continually scale up, making smaller values invisible.
|
|
Eventually the system would appear to be idle, only
|
|
graphing the biggest spikes. A similar issue affecting
|
|
the upper-right meter is also fixed. Meter scaling is
|
|
recalibrated every couple of minutes to avoid losing
|
|
meter funtionality after anomalously large peaks.
|
|
- I/O Monitor - Fixed rounding errors caused by use of
|
|
integer types, which were causing relatively small
|
|
values not to appear on graph or meter. Added code to
|
|
round very low values up, so they will appear on meter
|
|
and graph.
|
|
- ONGOING: Style edits to improve readability and
|
|
maintainability (removing hardcoded values, adding
|
|
newlines to "if" conditions, etc).
|
|
|
|
1.0b2 - Released 980520
|
|
- Vastly reduced CPU usage in CPU & IO mode,
|
|
MEM/SWAP/UPTIME (i.e. SysInfo) only updated
|
|
when visible now and now uses global file
|
|
descriptors to reduce filesystem overhead,
|
|
based on diff by Dave Harden (dharden@wisewire.com);
|
|
- Fixed memory overflow bug;
|
|
- Memory gauge now displays real used mem, buffered
|
|
& cached mem are no longer being displayed;
|
|
- Added -i & -s parameters to select startupmode, based
|
|
on diff by Brendan Knox (knoxy@origob.demon.co.uk);
|
|
|
|
|
|
1.0b1 - Released 980513
|
|
- First initial stable public BETA release.
