- Orchestrator reads your replication topologies (give it one server - be it master or slave - in each topology, and it will reveal the rest).
- It keeps a state of this topology. …
Here's our take of master DML query monitoring at Outbrain (presented April 2014). It took a half-day to code, implement, automate and deploy, and within the first hour of work we managed to catch multiple ill-doing services and scripts. You might want to try this out for yourself.
What's this about?
What queries do you monitor on your MySQL servers? Many don't monitor queries at all, and only look up slow queries on occasion, using …[Read more...]
