Welcome to the ScaleGrid Console developer hub. You'll find comprehensive guides and documentation to help you start working with ScaleGrid Console as quickly as possible, as well as support if you get stuck. Let's jump right in!

Get Started    

MySQL InnoDB Metrics

Analyze your MySQL hosting metrics with ScaleGrid DBaaS, including InnoDB storage engine I/O, row operations, buffer pool, transactions, log file usage, checkpoint age, and change buffer activity.

ScaleGrid MySQL hosting and database management solutions come with advanced monitoring metrics to help ensure the continuous health of your deployments. Each cluster comes with it's own unique MySQL Monitoring Console found on your cluster details page.

Click on your Monitoring icon to get started:

MySQL Hosting InnoDB Metrics

In this help doc, we're going to walk you through all of the MySQL metrics under the InnoDB tab of your Monitoring Console.

Find Your Other MySQL Deployment Metrics

MySQL Overview Metrics
MySQL Operating System Metrics
MySQL Replication Metrics

At the top of your MySQL Monitoring Console, you can use the dropdown menus to change the view for your MySQL master vs. slave(s), time period, and time zone.

You can also click the green Compare Servers link to analyze how your master and slave(s) perform side-by-side for any given time range.
