If you run several web servers in your organization or even public web servers on the internet, you need some kind of monitoring. If your servers go down for some reason, this may not be funny for your colleagues, customer, and even for yourself. Introduction. For that reason, we use monitoring tools.

MySQL does not limit the number of slaves that you can connect to the master server in a replication topology. A classic solution for this problem is to deploy a binlog server – an intermediate proxy server that sits between the master and its slaves. Ripple is an open source binlog server developed by Pavel Ivanov.
