    technik007_cz got a reaction from wildcat_paris in LANG et al env variables not properly set   
    Ok mate, but keep in mind the source of this problem can be in: corrupted system image, weak power adapter for your Lime2 board (there are lot of power adapters dropping voltage under load below "safe" values and only few good ones on the market), microSD or SD card has been removed after transferring system image too early (these card are slow and it still takes time to write all data even system say 100% written) or card reader is plugged in internal or external hub which is underpowered and causes data corruption during transfers.

    technik007_cz reacted to luca219 in Cubietruck Battery monitor with nagios   
    hi all,
    if someone need, I adapted for nagios the script to monitor battery cubietruck.
    The script is pnp4nagios friendly.
    #!/bin/bash ###################################################################################### # # Battery info # /usr/sbin/i2cset -y -f 0 0x34 0x82 0xC3 # read power OPERATING MODE register @01h POWER_OP_MODE=$(/usr/sbin/i2cget -y -f 0 0x34 0x01) BAT_EXIST=$(($(($POWER_OP_MODE&0x20))/32)) # divide by 32 is like shifting rigth 5 times CHARG_IND=$(($(($POWER_OP_MODE&0x40))/64)) # divide by 64 is like shifting rigth 6 times ######################################################################################## #read battery voltage 79h, 78h 0 mV -> 000h, 1.1 mV/bit FFFh -> 4.5045 V BAT_VOLT_LSB=$(/usr/sbin/i2cget -y -f 0 0x34 0x79) BAT_VOLT_MSB=$(/usr/sbin/i2cget -y -f 0 0x34 0x78) BAT_BIN=$(( $(($BAT_VOLT_MSB << 4)) | $(($(($BAT_VOLT_LSB & 0xF0)) >> 4)) )) BAT_VOLT=$(echo "($BAT_BIN*1.1)"|bc) # store maximum battery voltage to compare to if [ -f "/etc/default/battery" ]; then source "/etc/default/battery" else echo "MAX=$BAT_VOLT" > /etc/default/battery echo "MIN=3484" >> /etc/default/battery fi # integer is enough, cut down the decimals MAX=${MAX%.*} BAT_VOLT=${BAT_VOLT%.*} # mainline kernel shows battery existence even if not exists. this is walkaround if [ "$BAT_VOLT" -ge "3200" ]; then # if we have new max value, alter defaults if [ "$BAT_VOLT" -gt "$MAX" ]; then MAX=$BAT_VOLT sed -e 's/MAX=.*/MAX='$BAT_VOLT'/g' -i /etc/default/battery fi # if we have new min value, alter defaults if [ "$BAT_VOLT" -lt "$MIN" ]; then MIN=$BAT_VOLT sed -e 's/MIN=.*/MIN='$BAT_VOLT'/g' -i /etc/default/battery fi # calculate percentage percent=$(echo "($BAT_VOLT-$MIN)*100/($MAX-$MIN)"|bc) fi # define output format output="Load : $percent% | Load_Batt=$percent;80;35;3.4;4.2;" # if load% in range 80-10 ok if [ "$percent" -ge 80 -a "$percent" -le 100 ]; then echo "OK- $output" exit 0 # if load % in range 40-79 warning elif [ "$percent" -ge 40 -a "$percent" -le 79 ]; then echo "WARNING - $output" exit 1 # if load % in range 0-39 critical elif [ "$percent" -ge 0 -a "$percent" -le 39 ]; then echo "CRITICAL - $output" exit 2 # if check non riceve data else echo "UNKNOW" exit 3 fi if run script for non admin user need add permission to  /usr/sbin/iscget
    ex:
    chmod 777 /usr/sbin/iscget and change default permission for /dev/i2c-0
    ex:
    sudo nano /lib/udev/rules.d/60-i2c-tools.rules KERNEL=="i2c-0" , GROUP="i2c", MODE="0660" to
    KERNEL=="i2c-0" , GROUP="i2c", MODE="0666" and reboot
