check mysql slave sql running

This is redundant: it's built into the nagios-plugins published 'check_mysql' package, which is tested and maintained. Use 'check_mysql -S' and review the options desired.

I got the script to work.
the write left out the host part.
to fix this you need to answer line to:
answer=`$mysqlpath/mysql -u $user -p$pass -h $host -e 'show slave statusG' | /bin/grep Slave_SQL_Running | /usr/bin/cut -f2 -d:`

There's no support for a custom port. And the host parameter seems to be completely ignored.

works very well, thank you!
