Re: how do you control cpu usage of apps?

That should be OK.
Thanks for the feedback.

And thank you for educating me on LSB tags.

Re: how do you control cpu usage of apps?

Hi,

I'm trying to get the cpulimit script to run, but I'm running into the same "daemon can not be started" error/output. Would somebody mind taking a look and tell me what I may have mistyped?

It is located here: /etc/init.d/cpulimit

ls -all reports this:
-rwxr-xr-x 1 root root 1947 Oct  4 15:40 /etc/init.d/cpulimit

cpulimit contents:

#!/bin/sh
### BEGIN INIT INFO
# Provides:          cpulimit
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog

# Default-Stop:      0 1 6
# Short-Description: Start daemon at boot time
# Description:       Enable service provided by daemon.

set -e

case "$1" in
start)
if [ $(ps -eo pid,args | gawk '$3=="/usr/bin/cpulimit_daemon.sh"  {print $1}' | wc -l) -eq 0 ]; then
    nohup /usr/bin/cpulimit_daemon.sh >/dev/null 2>&1 &
    ps -eo pid,args | gawk '$3=="/usr/bin/cpulimit_daemon.sh"  {print}' | wc -l | gawk '{ if ($1 == 1) print " * cpulimit daemon started successfully"; else print " * cpulimit daemon can not be started" }'
else
    echo " * cpulimit daemon can't be started, because it is already running"
fi
;;

CPULIMIT_DAEMON=$(ps -eo pid,args | gawk '$3=="/usr/bin/cpulimit_daemon.sh"  {print $1}' | wc -l)
CPULIMIT_INSTANCE=$(ps -eo pid,args | gawk '$2=="cpulimit" {print $1}' | wc -l)
CPULIMIT_ALL=$((CPULIMIT_DAEMON + CPULIMIT_INSTANCE))
if [ $CPULIMIT_ALL -gt 0 ]; then
    if [ $CPULIMIT_DAEMON -gt 0 ]; then
        ps -eo pid,args | gawk '$3=="/usr/bin/cpulimit_daemon.sh"  {print $1}' | xargs kill -9   # kill cpulimit daemon
    fi

    if [ $CPULIMIT_INSTANCE -gt 0 ]; then
        ps -eo pid,args | gawk '$2=="cpulimit" {print $1}' | xargs kill -9                    # release cpulimited process to normal priority
    fi
    ps -eo pid,args | gawk '$3=="/usr/bin/cpulimit_daemon.sh"  {print}' | wc -l | gawk '{ if ($1 == 1) print " * cpulimit daemon can not be stopped"; else print " * cpulimit daemon stopped successfully" }'
else
    echo " * cpulimit daemon can't be stopped, because it is not running"
fi
;;
restart)
$0 stop
sleep 3
$0 start
;;
status)
ps -eo pid,args | gawk '$3=="/usr/bin/cpulimit_daemon.sh"  {print}' | wc -l | gawk '{ if ($1 == 1) print " * cpulimit daemon is running"; else print " * cpulimit daemon is not running" }'
;;
esac
exit 0

Any help would be appreciated!

Thank you

Nevermind. Found a copy paste error. Thanks anyway.
