Stagemonitor
An open-source Java application performance monitoring agent with preconfigured dashboards for Elasticsearch, Graphite, and InfluxDB.
What is Stagemonitor?
Stagemonitor is an open-source application performance monitoring (APM) agent for Java server applications. It collects metrics, request traces, and call stack data, integrating with time series databases like Elasticsearch, Graphite, and InfluxDB for analysis. The project includes preconfigured Grafana and Kibana dashboards to visualize performance data and help developers identify bottlenecks.
Java developers and DevOps teams running Java-based server applications who need an open-source, self-hosted APM solution for performance monitoring and troubleshooting.
Stagemonitor offers a tightly integrated, open-source APM stack with minimal setup, providing prebuilt dashboards and support for multiple time series databases. It gives teams full control over their monitoring data without vendor lock-in, making it a cost-effective alternative to commercial APM tools.
Overview
an open source solution to application performance monitoring for java server applications
Use Cases
Best For
- Monitoring performance of Java web applications in production
- Self-hosting APM infrastructure with Elasticsearch and Grafana
- Analyzing request traces and call stacks in Kibana
- Integrating OpenTracing-compatible distributed tracing
- Visualizing application metrics with preconfigured dashboards
- Collecting and storing time-series metrics from Java servers
Not Ideal For
- New projects requiring long-term support and active maintenance
- Teams looking for a fully managed, cloud-native APM solution with minimal infrastructure overhead
- Environments using time series databases not supported by Elasticsearch, Graphite, or InfluxDB
Pros & Cons
Pros
The lightweight Java monitoring agent automatically collects performance data with minimal configuration, as highlighted in the README, making it easy to integrate into existing Java applications.
Includes preconfigured Grafana and Kibana dashboards for immediate visualization of metrics and request analysis, reducing setup time and providing actionable insights out of the box.
Offers an open-source alternative to commercial APM tools, allowing teams full control over their monitoring data and avoiding vendor lock-in, as emphasized in the project's philosophy.
Supports the OpenTracing standard for distributed tracing, enabling integration with other tracing systems and enhancing observability in microservices architectures.
Cons
The README explicitly states the project is no longer maintained, meaning no updates, bug fixes, or security patches, which poses a risk for production use.
Requires integration with external time series databases like Elasticsearch, adding infrastructure complexity and maintenance overhead compared to all-in-one or managed APM solutions.
With no active development, the ecosystem lacks new features, community support, and may have compatibility issues with latest Java versions or frameworks.
