/usr/share/battery-stats/collect-csv prints errors when no batteries are connected, resulting in cron mail clutter like
-----8<------
Subject: Cron root@localhost if [ -x /usr/share/battery-stats/collect-csv ]; then /usr/share/battery-stats/collect-csv ; fi (failed)

-----8<------
battery-stats-collector exits 1 due to set -e when no battery is connected. In conjunction with the execution from a hook during pm-suspend, this effectively inhibits suspend/hibernate.
I have recently installed the package in Arch Linux to my HP Envy laptop. Data collection daemon works fine, and the data is available in /var/log/battery-stats
.
But when I try to view graph using battery-graph
, it shows an empty graph.
After some investigating, it turned out that on my system AC power adapter was not recognized by battery-stats-collector
(due to incorrect packaging, but it is not related to this issue).
After reading plot
command in /usr/bin/battery-graph
, it turns out that it shows blue line when charging, red line when discharging, and shows nothing when charging status is unknown.
I think we should instead show black or gray line for such data.
i get the following when running the flow program on my logfile:
[1239]anarcat@angela:battery-stats$ /usr/share/battery-stats/battery-stats-graph-flow

now, maybe it's because i have a screwed up CSV logfile, because I have used the procedure in #3 to convert my previous CSV files... you can reproduce the issue with the following .csv file:
timestamp,when,manufacturer,,technology,serial_number,status,cycle_count,energy_now,energy_full,energy_full_design,charge_now,charge_full,charge_full_design

not quite sure what is going on here...
Is there any way to save the graph as an image? As a flag to the battery-graph
command?
this is a rare case of when i think it is relevant to keep a larger amount of logs. the current configuration of the debian package only ships with 5 weeks of logs. that is not a long time to do proper analysis! for example, here's a graph i generated with the data I have so far, which is about 6 months:
it is barely usable, more samples would be great! this log file takes less than 1MB:
868K /var/log/battery-stats.csv
and will take 10 times less that when compressed:
$ gzip -c /var/log/battery-stats.csv | wc
226 1280 71159
so i would suggest bumping log rotation to "monthly" at least, and make that at least a year. I have set it to 4 years here, but that may be a little extreme:
/var/log/battery-stats {
rotate 208
delaycompress
missingok
notifempty
nocopytruncate
nomail
weekly
postrotate
if which invoke-rc.d >/dev/null 2>&1; then
invoke-rc.d battery-stats restart > /dev/null
else
/etc/init.d/battery-stats restart > /dev/null
fi
endscript
}
thanks!

battery-status-collect will collect statistics for all batteries that are present on the system, however battery-status-graph assumes that there is only one battery in the log file.
It would be great if battery-status-graph was able to generate separate graphs for each different battery.

Unfortunately I can't interpret what is needed from gnuplots changelog or I'd do an MR.
--persist
option keep graph window live.
however, because you remove the temp file,
window often crash when zoom or panning.
i suggest that use pause mouse close
which make gnuplot wait til window close.
then you can remove temperary file safely after gnuplot exit.
this would be a easy patch like this. do you want me to send pull request?

for some reason, this software cannot read the files created from the older "battery-status" version. i get this error:
$ /usr/share/battery-stats/battery-stats-graph /var/log/hjemmenett-battery-status.log

is there a way to convert the files over? my original python version still works:

... and crap, it looks like my battery is already at 80% effective capacity!
In battery-stats-collector
when get_logline
is unable to determine a value for ac_online
it echoes a message warning that "No power supply found". This line then goes to the log file before the status line is echoed.
That way the generated file becomes unusable since every two lines it contains non-data. On my host it looks likes something like :
No power supply found
1474886747 56.11 1 2016/09/26 12:45:47 -
No power supply found
1474886807 56.45 1 2016/09/26 12:46:47 -
No power supply found
1474886867 56.82 1 2016/09/26 12:47:47 -
The warning line should not be echoed, or at least not on stdout.
I just installed from git and it appears that no init script gets installed by default. I will share the systemd script I created for my system:
# cat /etc/systemd/system/battery-stats-collector.service
[Unit]
Description = battery-stats-collector daemon
[Service]
Type = simple
PIDFile = /run/battery-stats-collector.pid
ExecStart = /usr/local/sbin/battery-stats-collector
Restart = on-abort
StartLimitInterval = 60
StartLimitBurst = 10
[Install]
WantedBy = multi-user.target
The config file /etc/battery-stats.conf, refers to a certain /etc/init.d/battery-stats script for INIT based systems:
# Default configuration for battery-stats-collector
#
# This file is sourced from /etc/init.d/battery-stats ; it should follow normal
# /bin/sh syntax.
.....
But no such init script is installed during make install, or indeed appears to be present in the git repo.
# battery-stats-collector[22270]: cat: /sys/class/power_supply//sys/class/power_supply/AC/online: No such file or directory
Note the double slash. This was after a recent update from git.
I'm using the AUR git package here https://aur.archlinux.org/packages/battery-stats-git
git commit 2d3675357de73023b29f3cb4fc9b882624f871a2
was working fine.
for some reason, suspend/resume hooks don't run here and the data doesn't get collected then.
i have /etc/pm stuff installed here:
$ dpkg -S /etc/pm
unattended-upgrades, toshset, pm-utils: /etc/pm
i am not sure they get fired when my laptop gets suspended/resumed, but then again, i am not sure how that happens in the first place. it may be systemd doing the suspend, but it could also be the laptop's BIOS as well: it's unclear. i know that suspend happens when i close the lid, but that's about it.
later:
http://askubuntu.com/questions/609695/does-systemd-read-etc-pm explain
that /etc/pm/ is ignored by systemd, and suggest to provide units in
/lib/systemd/system-sleep/ instead.

the python script i wrote is still in the package, but not the default and worse, it's actually broken now:
