Re: [qubes-users] Help finetuning i3status in Qubes dom0 [solved]
Hello Ilpo,
amazing, thank you for the quick tip!
I was able to get exactly what I was looking for (see attached screenshot)
I can now get my summarized RAM usage via:
[USER@dom0 ~] xl list | awk '{print $3}' | tail -n +2 | paste -s -d+ - | bc
15022
as such I have edited my /usr/bin/qubes-i3status to add the RAM usage to my
status bar near the "running qubes section"
status_qubes() {
# Output in Status bar, ex: 6 Qubes using 15.050 MB RAM
local sum_ram="("$(xl list | awk '{print $3}' | tail -n +2 | paste -s -d+
-)")/1000"
local sum_ram=$(bc <<< "scale=3;$sum_ram")"MB"
local qubes=$(qvm-ls 2>/dev/null | grep ' \* ' | wc -l)
json qubes "$qubes Qubes using $sum_ram RAM"
}
or if you want to have the output as with "15.0G" instead of "15.050MB":
status_qubes() {
# Output in Status bar, ex: 6 Qubes using 15.0G RAM
local sum_ram="("$(xl list | awk '{print $3}' | tail -n +2 | paste -s -d+
-)")/1000"
local sum_ram=$(bc <<< "scale=1;$sum_ram")"G"
local qubes=$(qvm-ls 2>/dev/null | grep ' \* ' | wc -l)
json qubes "$qubes Qubes using $sum_ram RAM"
}
Maybe someone more skilled can write a subroutine in qubes-i3status so that it
can be enabled or disabled by the user like with all other party in the main()
area.

[qubes-users] Help finetuning i3status in Qubes dom0
Hello,
after switching to i3vm in Qubes 3.2 as primary window manager I'm working on
tweaking it to my needs.
I've learned that Qubes is adding a small script to generate the status bar in
i3:
/usr/bin/qubes-i3status
I'd like to add the total consumed RAM in the status bar, but my scripting is
not good enough to make it work, can someone give me a hint?
My current approach:
1) get the used RAM for each AppVM from running 'xl list' in dom0
[USER@dom0 ~]$ xl list
NameID Mem VCPUs State Time(s)
dom0 0 4061 4 r- 902.7
sys-net 1 297 2 -b 61.1
sys-firewall 2 1424 2 -b 74.3
sys-usb 3 1023 2 -b 54.3
win7 4 4095 2 -b 298.9
win7-dm 544 1 -b 92.2
untrusted6 3999 2 -b 492.9
2) Extracted only the column which includes the RAM with
[USER@dom0 ~]$ xl list | awk '{print $3}'
Mem
4061
297
1424
1023
4095
44
3999
**
QUESTION: How can I remove the first line?
**
3) If I get rid of the first line, I could add everything up.
Looking here:
https://unix.stackexchange.com/questions/320217/how-to-calculate-the-the-value-of-each-line-with-awk-command
the command to do so would be:
[USER@dom0 ~]$ xl list | awk '{print $3}' | paste -s -d+ -
which will create:
4061+297+1424+1023+4095+44+3999
4) passing this to bc should give me the total RAM:
[USER@dom0 ~]$ xl list | awk '{print $3}' | paste -s -d+ - | bc
If someone is interested in additional tweaks to i3status:
I've added some changes to this file to format date and time and more important
to get better battery metrics as I like to keep an eye on the current discharge
rate to learn how system load is impacting battery runtime.
This is also usefull to learn how optimizations like tlp will influence battery
runtime etc.
[...]
status_bat() {
local my_bat=/sys/class/power_supply/BAT0
local bat_rate=$(bc <<< "scale=1;`cat $my_bat/current_now`*`cat
$my_bat/voltage_now`/10^12")"W"
local bat=$((100*`cat $my_bat/charge_now`/`cat $my_bat/charge_full_design`))
local ac=''
local color=''
if [[ $(cat /sys/class/power_supply/AC/online) == '1' ]]; then
ac=' AC'
elif ((bat < 25)); then
color='#ff' # red
elif ((bat < 50)); then
color='#ff6600' #was #00 = yellow before
fi
json bat "Bat: $bat_rate $bat%$ac" "$color"
}
