This one is for coders:

Code:

function genoil_statics ()

{
#### Arrange the output for Genoil statics

if [[ "$ETHMINER_or_GENOIL_or_CLAYMORE" == "GENOIL" ]]; then

   # Check if Genoil is running. Note that I have to search the full path as there is a few miners with the same exec's name
   ps aux | grep -v grep | grep miner | grep -q "$KEY_GENOIL"
   if [[ $? -eq 0 ]]; then
   GENOIL_IS_RUNNING="YES"
   TIMEOUT_FOR_TIMEOUT_IN_SECONDS=20 # The timeout for the command timeout to wait
   GENOIL_NUMBER_OF_HASHRATES_TO_SHOW=3 # Default 3, and I want to keep this value independent for each miner
   echo
   echo "It seems that GENOIL is running!!"

   # Extract the output from screen
   echo "Running timeout+script+screen for $TIMEOUT_FOR_TIMEOUT_IN_SECONDS seconds"
   timeout $TIMEOUT_FOR_TIMEOUT_IN_SECONDS script -q ~/kk003_telegram_data/files/output_miner_from_screen --command "screen -dr miner"
   sleep 2
# screen -d miner # does not seem to need to be Detached

   # I don't see any valuable information than the total hashrate (I'll show a few at last)
   # Surprise!!!, sed 's/ /\n/g' no convierte espacios en saltos de linea, pero la misma linea en la consola si lo hace!!!
   TOTAL_HASHRATE=$(cat ~/kk003_telegram_data/files/output_miner_from_screen | grep "Mining on PoWhash" | cut -d":" -f4 | cut -d" " -f2 | sed 's/ /\n/g' | tail -$GENOIL_NUMBER_OF_HASHRATES_TO_SHOW

   # Mount the little thing Genoil gives us
   #
   echo "Latest total hashrates : " > ~/kk003_telegram_data/files/miner_statics.txt
   echo $TOTAL_HASHRATE >> ~/kk003_telegram_data/files/miner_statics.txt

   echo "Latest total hashrates : " > ~/kk003_telegram_data/files/miner_statics_log_file.txt
   echo $TOTAL_HASHRATE >> ~/kk003_telegram_data/files/miner_statics_log_file.txt

   # Insert the Title for Genoil mining information
   sed -i "1s/^/** Genoil mining Information **\n/" ~/kk003_telegram_data/files/miner_statics.txt
   sed -i "1s/^/\n/" ~/kk003_telegram_data/files/miner_statics.txt

   sed -i "1s/^/** Genoil mining Information **\n/" ~/kk003_telegram_data/files/miner_statics_log_file.txt
   sed -i "1s/^/\n/" ~/kk003_telegram_data/files/miner_statics_log_file.txt

   else
   echo "Genoil does not seem to be running!!. Skiping this bit."
   GENOIL_IS_RUNNING="NO"
   fi
fi
}

I found out a way to capture the output from screen in real time. See the lines:

Code:

# Extract the output from screen
   echo "Running timeout+script+screen for $TIMEOUT_FOR_TIMEOUT_IN_SECONDS seconds"
   timeout $TIMEOUT_FOR_TIMEOUT_IN_SECONDS script -q ~/kk003_telegram_data/files/output_miner_from_screen --command "screen -dr miner"
   sleep 2
# screen -d miner # does not seem to need to be Detached

This run screen for 20 seconds (timeout command) and saves output to file ~/kk003_telegram_data/files/output_miner_from_screen (script command). -dr forces to attach miner (so if user have screen open in a terminal will close it and the script will do its job). After 20 seconds miner is detached without need to send CTRL+d.
This works better if ran from a non interactive terminal, ejem: from nvoc system Tongue

.

This means it is possible to capture the output of any miner even if all of it shows only on terminal (no log file, web server, argument -L on screen, etc).
I hope it will be useful for you too.

PD: if you use "tail -f file" to watch the output in real time don't trust what you see. The real output is in the file (do a cat file or whatever). Keep in main, if you log the output of your script probably you'll get those 20 seconds from screen in the log file too.

Nice; this is very useful. Even as a methodology it can be applied to many different features.

I am sorry to say that I have tested this method all night and it is unstable. At any given moment stop writing the file.

Finally I think this method will work to start screen's log file "on the fly"

Code:

screen -dr miner -X log

So some code like this would do the trick:

Code:

# First check if screen is running miner with the -L flag!!!
......
......

# End of first check if screen is running miner with the -L flag!!!

if [[ -f ~/screenlog.0 ]]; then
> ~/screenlog.0
screen -dr miner -X log # Start login output from miner
sleep 20 # keep saving data for 20 seconds
screen -dr miner -X log # Stop login output from miner
# Get the miner statics
TOTAL_HASHRATE=$(tail -60 ~/screenlog.0 | grep "Mining on PoWhash" | cut -d":" -f4 | cut -d" " -f2 | sed 's/ /\n/g' | tail -3)
.....
.....

fi

I will add this method to kk003_telegram ASP + some new features and miners for statics.
Hope it helps.
