Minimal Conky with HDD data, nVidia core temperature and Dell fan speed

Minimal, text-based conky scripts to show a really sophisticated system monitor.

conky

This is my updates conky screenshot, with the following capabilities:

  • CPU, RAM, disk I/O usage
  • CPU, GPU (nVidia), motherboard temperature and fan speed (Dell Latitude E series)
  • power usage on battery mode
  • Ethernet and WLAN status
  • disk health and temperature

Additional programs in need

  • hdsentinel1
  • dellfand2

This conky needs root privileges to run, because it reads informations like disk S.M.A.R.T. data, so add the following to the end of/etc/sudoers

YOUR_USERNAME ALL=(root) NOPASSWD: /usr/bin/hdsentinel , /usr/bin/conky , /usr/bin/dellfand

Additional scripts

for hdsentinel

In order to get hdsentinel output readable, a small additional script is needed.

If there’s no parameter given, it lists all the available drives with formatted informations. Alternatively, it can take two parameters, first for the drive (for example sda or /dev/sda), the second for the needed information. If the second parameter is not given, the same row will be displayed as before for all the drives, but only for the drive in parameter one.

I placed this script in /home/USERNAME/.conky/hdsentinel_ hdsentinel.sh

#!/bin/bash

if [ -n "$1" ]; then
data=`sudo hdsentinel -solid | grep $1`
temp=`echo $data | cut -d" " -f2`
health=`echo $data | cut -d" " -f3`
hours=`echo $data | cut -d" " -f4`

if [ -n "$2" ]; then
case $2 in
"temp")
echo $temp
;;
"health")
echo $health
;;
"hours")
echo $hours
;;
esac
else
echo "$temp°C    $health%    health    $hours hours"
fi
else
devs=`ls /dev/ | grep -v [0-9] | grep sd`

for device in ${devs[*]}
do
data=`sudo hdsentinel -solid | grep $device`
disk=`echo $data | cut -d" " -f1`
temp=`echo $data | cut -d" " -f2`
health=`echo $data | cut -d" " -f3`
hours=`echo $data | cut -d" " -f4`
echo "$device      $temp°C    $health% health    $hours hours"
done
fi

for dellfand

Dellfand somewhy scales the turn/min with a 30 factor, so it needs to be reduced.

I placed this script in /home/USERNAME/.conky/dellfand_

dellfand.sh

#!/bin/bash

SPEED=`sudo dellfand | cut -d" " -f7`
let SCALED=$SPEED/30
echo $SCALED

for power usage

Power usage need to be calculated from the battery’s current state, therefore you first need to find you battery. It’s usually in /proc/acpi/battery/BATTERY_NAME/. If in this directory, there’s information in the state file (cat state), you’ve find your battery.

The script takes two paramters, the first is needed, it’s the BATTERY_NAME from /proc/acpi/battery/BATTERY_NAME/, the second is for the needed information, and it’s optional: voltage, current or power. If the second is not given, all three information will be displayed.

I placed this script in /home/USERNAME/.conky/power_

powerusage.sh

#!/bin/bash

volt=`cat /proc/acpi/battery/$1/state | grep "present voltage" | awk '{print $3}'`
ampere=`cat /proc/acpi/battery/$1/state | grep "present rate" | awk '{print $3}'`

volt=`echo "scale=2;$volt/1000"|bc`
ampere=`echo "scale=2;$ampere/1000"|bc`
power=`echo "scale=2;$volt*$ampere"|bc`

if [ -n "$2" ]; then
case $2 in
"voltage")
echo $volt
;;
"current")
echo $ampere
;;
"power")
echo $power
;;
esac
else
echo "Voltage: " $volt "V"
echo "Current: " $ampere "A"
echo "Power: " $power "W"
fi

The conky scripts

The starter script

In order to start all conky scripts, a wrapper script was needed. It was placed in /home/USERNAME/.conky/conky_start

conky_start.sh

#!/bin/bash

sudo conky -c /home/USERNAME/.conky/conky_clock -d
sudo conky -c /home/USERNAME/.conky/conky_sys -d
sudo conky -c /home/USERNAME/.conky/conky_hdd -d
sudo conky -c /home/USERNAME/.conky/conky_io -d
sudo conky -c /home/USERNAME/.conky/conky_net -d
