This Tool provides the means to monitor the performance of Spring Batch applications without the need to manipulate the respective code basis.
Through Listeners and AOP it evaluates the throughput of a monitored Job and writes the result to a simple database-schema (a file-based H2 by default).
It measures the performance of Job, Step, Chunk, Reader/Processor/Writer/Tasklet down to indivdual Items.
- Add the dependency to your POM:
<dependency>
<groupId>de.viadee</groupId>
<artifactId>springBatchPerformanceMonitoring</artifactId>
<version>...</version>
</dependency>- Add the de.viadee.spring.batch.infrastructure.Configurator.class to your Spring-Application-Context (via @Import on your Configuration)
- Run the Job
- By default the monitoring result is written to project-folder/target/database/monitoringDB.mv.db
You can access the database with the credentials sa/sasa. It contains all perfomance data measured in snowflake style as well as number of prepared views for typical questions on all the detail levels mentioned above. You can see the SQL schema in H2 syntax in the code.
This library will remain under an open source licence indefinately.
We follow the semantic versioning scheme (2.0.0).
In the sense of semantic versioning, the resulting database schema is the only public API provided here. We will keep the database schema as stable as possible, in order to enable users to analyse performance logs with the toolsets of their choice.
For the same reason, we do not use any database specific features and we minimize the assumptions made regarding Spring versions and the whole runtime environment.
Feel free to add issues, questions, ideas or patches. We are looking forward to it.
