JVM (Micrometer)

Dashboard for Micrometer instrumented applications (Java, Spring Boot, Micronaut)

JVM (Micrometer)

A dashboard for Micrometer instrumented applications (Java, Spring Boot, Micronaut).

Features

  • JVM memory
  • Process memory (provided by micrometer-jvm-extras)
  • CPU-Usage, Load, Threads, Thread States, File Descriptors, Log Events
  • JVM Memory Pools (Heap, Non-Heap)
  • Garbage Collection
  • Classloading
  • Direct-/Mapped-Buffer
  • minimalist I/O Overview
    • HTTP - Rate, Errors, Duration
    • TOMCAT/JETTY - Utilisation

Note

Instead of using the job tag to distinct different applications, this dashboard makes use of a common tag called application applied to every metric.

In a Spring Boot setting, this could look like this:

@Bean
MeterRegistryCustomizer<MeterRegistry> configurer(
    @Value("${spring.application.name}") String applicationName) {
    return (registry) -> registry.config().commonTags("application", applicationName);
}

Or since Micrometer 1.1.0 with a property:

management.metrics.tags.application=${spring.application.name}
