Machine Learning with MySQL HeatWave and predictions in Grafana

In MySQL HeatWave, the Database as a Service (DBaaS) offered by Oracle, Machine Learning is incorporated to provide database administrators (DBAs) and developers with an optimal experience.

Those tools are the Auto ML advisors like the autopilot indexing for example.

MySQL HeatWave is also an invaluable asset for Data Analysts, offering straightforward tools that streamline the process of creating predictive models through data training and scoring.

The Data

The data we are using is the Bank Marketing data related to marketing campaigns over phone calls of a Portuguese banking …

RED Method for MySQL Performance Analyses

The RED Method (Rate, Errors, Duration) is one of the more popular performance monitoring approaches.  It is often applied to Monitoring Microservices though there is nothing that prevents it from being applied to databases like MySQL.

In Percona Monitoring and Management (PMM) v2 we have all the required information stored in the ClickHouse database, and with the built-in ClickHouse datasource it is a matter of creating a dashboard to visualize the data.

While I was editing the dashboard, I added a few other panels, beyond what RED Method requires, in order to show some of the cool things you can do with Grafana + ClickHouse data source and …

Grafana Dashboard For Monitoring Debezium MySQL Connector

Debezium has packed with monitoring metrics as well. We just need to consume and expose it to the Prometheus. A lot of use of useful metrics are available in Debezium. But unfortunately, we didn’t find any Grafana dashboards to visualizing the Debezium metrics. So we built a dashboard and share it with the Debezium community. Still, a few things need to improve, but almost all the metrics are covered in one single dashboard.

Debezium MySQL monitoring metrics:

Debezium MySQL connector has three types of metrics.

  1. Schema History — Track the schema level changes.
  2. Snapshot — Track the progress about the snapshot.
  3. Binlog — Real-time reading binlog events.

Setup Monitoring for MySQL connector:

We need to install JMX exporter for monitoring the debezium MySQL connector. We have already blogged about this with detailed steps.

Monitor Debezium MySQL Connector With Prometheus And Grafana

Debezium is providing out of the box CDC solution from various databases. In my last blog post, I have published how to configure the Debezium MySQL connector. This is the next part of that post. Once we deployed the debezium, to we need some kind of monitoring to keep track of whats happening in the debezium connector. Luckily Debezium has its own metrics that are already integrated with the connectors. We just need to capture them using the JMX exporter agent. Here I have written how to monitor Debezium MySQL connector with Prometheus and Grafana. But the dashboard is having the basic metrics only. You can build your own dashboard for more detailed monitoring.

Reference: List of Debezium monitoring metrics

Install JMX exporter in …

Grafana Plugins and Percona Monitoring and Management

Percona Monitoring and Management (PMM) is built upon the shoulder of giants like Prometheus and Grafana. And speaking of Grafana, one of the coolest features that come with it is the ability to customize the experience through 3rd party plugins.

Plugins are an easy way to enhance the ability to have specialized graphs. One case that we saw in Managed Services is the ability to have a throughput graph, that shows QPS vs Threads running. This is different in essence of the “default” graphs that show a metric against time (time being the X-axis) since what we wanted is to show queries per second not during a time (that graph already exists) but for specific values of threads.

One way to achieve that is by using a plugin called Plotly

PMM’s Custom Queries in Action: Adding a Graph for InnoDB mutex waits

One of the great things about Percona Monitoring and Management (PMM) is its flexibility. An example of that is how one can go beyond the exporters to collect data. One approach to achieve that is using textfile collectors, as explained in  Extended Metrics for Percona Monitoring and Management without modifying the Code. Another method, which is the subject matter of this post, is to use custom queries.

While working on a customer’s contention issue I wanted to check the behaviour of InnoDB Mutexes over time. Naturally, I went straight to PMM and didn’t find a graph suitable for my needs. No graph, no problem! Luckily anyone can enhance PMM. So here’s how I made the …
