munin for xinetd
like a munin
make a script
$ vim /usr/local/bin/mm
#!/bin/bash
read arg0 arg1
arg0=$(echo $arg0 | tr -d "\r" | tr -d "\n");
arg1=$(echo $arg1 | tr -d "\r" | tr -d "\n");
echo "#"
#if [ $# -eq 0 -o $arg1 = "cpu" ]; then
echo "cpu `ps aux | awk '{total = total + $3} END{print total}'`"
#fi
echo "memory `free | awk '/buffers\/cache/{print $3/($3+$4)*100}'`"
echo "hdd `df --portability | awk '/md0/{print $3/($3+$4)*100}'`"
echo "."
regist xinetd
$ vim /etc/xinetd.d/mm
service mm
