I wanted to ask if someone has some documentation or links about monitoring ejabberd-clusters, and/or mysql-clusters.
We have aws multi region ejabberd cluster now. but because of the size of the project i want to switch to mysql from mnesia for the huge tables.
I am setting up right now a pacemaker/corosync HA cluster in each region and then want to do master-master replication between the regions.
Has someone exp about the monitoring and event-handling of something like that? Or do i need to wait for problems and then add the script out of them?
