Shell Script / Tool to check the MySQL Replication Status? Possible Duplicate:
  Monitoring replication on mysql  




I am running with MySQL Master/Slave Replication on Linux.

Is there any tool/Shell script which monitors the Replication Status and send the email alerts when there is Replication failure.
If you don't have a monitoring framework in place, I would highly recommend looking into Nagios. There are others, but for the purpose of this question, Percona has many MySQL monitoring tools available. Two of them specifically monitors slave lag and slave failures. From their blog post:


  The pmp-check-mysql-replication-delay plugin checks for excessive delay, and pmp-check-mysql-replication-running checks that replication is functioning correctly.
