Monitoring Spring

This spring integration adds monitoring to your MeshineryApplications:

• Automatically track the execution time of all tasks
• Show the current usage of all tasks (eg how much threads are currently blocked)
• Show the capacity of the RoundRobingScheduler
• General informations like task and processor count etc.

Installation

<dependency>
    <groupId>io.github.askmeagain</groupId>
    <artifactId>meshinery-monitoring-spring</artifactId>
    <version>0.1.3</version>
    <type>module</type>
</dependency>

1. Install package
2. Add @EnableMeshinery annotation to your Spring application (to register the StartupHooks).
3. Add @EnableMeshineryMonitoring to your Spring application.

Metric endpoints

for prometheus metrics. In the future there will be different formats if needed.

localhost:port/metrics/prometheus

Add own metrics

This package uses prometheus/client_java to collect and expose all the metrics. Just create a new metric and register this metric to

MeshineryMonitoringService.registry

and the metric will be exposed.

Beans

• TimingDecorator, to measure timings of processor executions. Will be registered automatically
• StartupHooks to add the following metrics to the registry:
  • "todoqueue" -> number of TaskRuns in the todoQueue
  • "todoqueue_open_capacity" -> capacity of the todo queue
  • "registered_tasks" -> number of all registered tasks
  • "processors_per_task" -> number of registered processors per task (includes hidden one!)
