Question

Where to find database standby node usage stats

We’ve run a multi-node MySQL database on DO since they first offered their managed MySQL database. Having recently had to upgrade again to the $240/m nodes the costs are getting high and I’m wondering if we really need the standby nodes. Does anyone know where I can see stats on standby node usage in my account? I’ve never noticed it anywhere but it feels like a pretty essential bit of data.

Hi @cmullin,

Yes, you are correct that standby nodes are essential, at least for high availability.

In the event of a failure, Managed Databases will automatically switch data handling to a standby node to minimize downtime.

The data between the nodes is being replicated using SQL replication.

All database clusters have automated failover, meaning they automatically detect and replace degraded or failing nodes.

With one standby node, if the primary node fails, the service remains available. The standby node is immediately promoted to primary and begins serving requests while a replacement standby node is provisioned in the background, More about that here;

In regards to statistics, I’m not sure it’s available at this time. Having said that, it’s a great idea which can be posted in the ideas bord.
