系统指标

DeepSeek V3 中英对照 System System Metrics

Micrometer 提供了多个用于系统监控的绑定器：

• 磁盘空间指标

• 文件描述符指标

• 处理器指标

• 运行时间指标

系统磁盘空间指标

// Usage example
new DiskSpaceMetrics(new File(System.getProperty("user.dir"))).bindTo(registry);

assertThat(registry.get("disk.free").gauge().value()).isNotNaN().isGreaterThan(0);
assertThat(registry.get("disk.total").gauge().value()).isNotNaN().isGreaterThan(0);

java

系统文件描述符指标

// Usage example
new FileDescriptorMetrics(Tags.of("some", "tag")).bindTo(registry);

assertThat(registry.get("process.files.open").tags("some", "tag").gauge().value()).isGreaterThan(0);
assertThat(registry.get("process.files.max").tags("some", "tag").gauge().value()).isGreaterThan(0);

java

系统处理器指标

// Instrumentation setup
new ProcessorMetrics().bindTo(registry);

// Usage example
assertThat(registry.get("system.cpu.usage").gauge().value()).isNotNegative();
assertThat(registry.get("process.cpu.usage").gauge().value()).isNotNegative();

java

系统运行时间指标

// Usage example
MeterRegistry registry = new SimpleMeterRegistry(SimpleConfig.DEFAULT, new MockClock());
new UptimeMetrics(runtimeMXBean, emptyList()).bindTo(registry);

assertThat(registry.get("process.uptime").timeGauge().value()).isEqualTo(1.337);
assertThat(registry.get("process.start.time").timeGauge().value()).isEqualTo(4.711);
