Out of the box config to switch to master on slave sinc delays from master (2 replies)

Hi, there is some out of the box configuration to switch to master when delays are detected on slaves?

I'm using Replication, with a Master-Slave configuration, using readOnly flag to switch between them.

But when i set readOnly true, i need to switch to master if delays are detected on slave. With "delays" i mean that the slave is x seconds_behind_master(show slave status). I'm not talking about timeouts.

Thanks in advance,
Sebastian
