wireless plugins: Interpret noise/power values >100 as (dBm + 256).
Hi list,
I currently develop an embedded statistics application and web interface
for OpenWrt Kamikaze based on Collectd and RRDTool.
While working with the wireless plugin I noticed some incompatibilities
with different drivers, namely the Broadcom proprietary driver and madwifi.
/proc/net/wireless on Broadcom:
Inter-| sta-| Quality | Discarded packets | Missed | WE
face | tus | link level noise | nwid crypt frag retry misc | beacon | 18
wl0: 0000 2. 179. 163. 0 0 8040 723 0 0
With the Broadcom proprietary driver you get the actual signal and noise
dbm units by substracting 255 from the values in /proc:
level: 179 - 255 = -76 dBm
noise: 163 - 255 = -92 dBm
/proc/net/wireless on Atheros SoC:
Inter-| sta-| Quality | Discarded packets | Missed | WE
face | tus | link level noise | nwid crypt frag retry misc | beacon | 22
ath0: 0004 21. -73. -94. 21841 0 0 0 0 0
Madwifi writes the actual dBm values into /proc.
So we have (at least for now) three possible types of values:
( x > 0.0 && x <= 100.0 ) current implementation: x is in percent (?)
( x > 100.0 && x <= 255.0 ) broadcom: range intersects with percents but
values below 100.0 (100.0 - 255.0 = -155.0 dBm)
are somewhat unlikely to occur
( x < 0.0 ) atheros: value is already in dBm
A patch which implements the two additional possibilities in collectd's wireless
plugin can be found in the OpenWrt Trac:
https://dev.openwrt.org/browser/packages/utils/collectd/patches/200-wireless-compat.patch
The patch was made against v4.4.0 of collectd but should work with v4.4.1 too.
It would be nice to have this in the next release or so :)

disk plugin: Use correct name under Linux 2.4
Hello everybody.
I have noticed that disk graphs are displayed by collection.cgi as
disk (71687000) instead of the correct disk name on 2.4.x linux
kernels.
The problem seems caused by the fact that the position of disk name of
/proc/partitions (used in 2.4 kernels) differs from /proc/diskstats
(used in 2.6 kernels).
I include as attachment a patch that seems to fix this problem.
I have tested it on 2.4.20 (REDHAT 9) and 2.6.24.4 (Debian Sid) systems.
Thanks a lot for Collectd. It is a _very_ useful program.
