From Reactive to Proactive: Monitoring and Alerting with Prometheus and Grafana

At Automatyze, we specialize in delivering practical software development services that help businesses operate more efficiently. Recently, we implemented a comprehensive monitoring solution for a customer’s data processing platform using Grafana, Prometheus, and Prometheus Alertmanager. This case study outlines how we improved the reliability of the platform by providing real-time monitoring and proactive alerting, ensuring smooth operation and minimizing downtime.

The Challenge

Our customer runs a Kubernetes-based data processing platform that handles large volumes of data on a daily basis. The platform required reliable monitoring of several critical areas:

  • Platform Key Performance Indicators (KPIs): Ensuring the system’s overall performance and throughput.
  • Kubernetes Cluster metrics: Monitoring the health and resource usage of the Kubernetes clusters.
  • Java Virtual Machine (JVM) metrics: Tracking the performance of Java-based components such as memory usage and thread activity.

The customer faced difficulties in detecting issues early enough to prevent disruptions in their data pipelines. They needed a monitoring system that would provide:

  • Real-time insights into system performance.
  • Proactive alerts that notified the team of potential issues before they escalated.
  • Actionable data to help optimize the platform’s performance.

The Solution

To address these challenges, we implemented a monitoring solution using Prometheus for collecting metrics, Grafana for visualizing data, and Prometheus Alertmanager for handling alerts. Here’s how we structured the solution:

Metrics collection with Prometheus

We set up Prometheus to gather metrics from three primary sources:

  • Platform KPI metrics: We defined and collected custom metrics that tracked the platform’s data processing workflows, such as throughput and processing times.
  • Kubernetes Cluster metrics: Prometheus collected key performance data from the Kubernetes clusters, including CPU usage, memory consumption, and pod health.
  • JVM metrics: Prometheus was configured to track JVM-related metrics, including memory usage, garbage collection, and thread activity, which were critical for monitoring the Java-based components.

Dashboards with Grafana

We created a set of Grafana dashboards that provided clear visualizations of the collected metrics, allowing the customer to easily monitor system health and performance.

KPI dashboards provided a real-time overview of the platform’s key performance indicators. Kubernetes dashboard showed the state of the Kubernetes cluster, including resource usage and node status. JVM Dashboard provided detailed insights into the performance of Java components, helping the team to manage memory usage and thread performance effectively.

Alerting with Prometheus Alertmanager

We configured Prometheus Alertmanager to handle alert notifications based on key thresholds, ensuring the customer’s team could respond promptly to any issues.

  • Alert definitions: We worked with the customer to define meaningful alert rules based on the most critical metrics. These alerts were set to trigger only when intervention was needed, such as when resource limits were exceeded or system components failed.
  • Alert routing: Alerts were sent to the appropriate team members depending on their severity. Critical alerts were routed to the on-call engineers, while lower-priority notifications were sent to a shared Slack channel for monitoring.
  • Silencing rules: We implemented silencing rules to suppress alerts during scheduled maintenance windows, reducing unnecessary notifications.

The Outcome

By deploying this monitoring solution, we provided the customer with a more efficient and reliable way to monitor their platform and respond to potential issues:

  • Real-time monitoring: The customer’s team gained immediate access to up-to-date system performance metrics through Grafana dashboards, allowing them to quickly identify and address any issues.
  • Proactive alerts: The alerting system ensured that the team was notified as soon as a problem arose, helping them prevent downtime and maintain consistent platform availability.
  • Improved efficiency: The detailed dashboards and alerting system provided the customer with valuable insights, enabling them to make informed decisions about system performance and optimization.

Conclusion

This monitoring solution, based on Grafana, Prometheus, and Prometheus Alertmanager, allowed our customer to maintain high availability and optimize their platform’s performance.
