The purpose of the following is to ensure that the script is executed when we are in the bin directory, otherwise the monitoring scripts, messages and logs may not be found

if [$last _dir = = "Bin"] | | [$last _dir = = "bin/"]; Then
Conf_file= ". /conf/mon.conf "
Else
echo "You shoud cd bin dir"
Exit
Fi
exec 1>>. /log/mon.log 2>> /log/err.log
echo " date +"%F %T" load Average"
/bin/bash. /shares/load.sh
#先检查配置文件中是否需要监控502
If Grep-q ' to_mon_502=1 ' $conf _file; Then
Export log=grep ‘logfile=‘ $conf_file |awk -F ‘=‘ ‘{print $2}‘ |sed ‘s/ //g‘
/bin/bash??.. /shares/502.sh
