I use a simple script that does the following: --- snip --- mysql -e "SELECT * from table_name limit 1" db > 2>/tmp/filename x=`cat /tmp/filename` if [ "$x" = "" ] then do_nothing=1 else ## There's an issue! echo "ERROR!" fi --- end snip ---
Using the re-direct of stderr is the key. the "2>/tmp/filename" sends all error output to the /tmp/filename file. If there are no errors, the file will be empty. I run it as a cron job every ten minutes, and if there is an error, it pages me. Keeps me in the know! -----Original Message----- From: Sascha Kettner [mailto:[EMAIL PROTECTED]] Sent: Friday, January 04, 2002 5:53 AM To: [EMAIL PROTECTED] Subject: Watchdog für mysql in Perl? Hi!
