Class JvmClassLoadingMetrics

java.lang.Object

io.prometheus.metrics.instrumentation.jvm.JvmClassLoadingMetrics

public class JvmClassLoadingMetrics
extends Object

JVM Class Loading metrics. The JvmClassLoadingMetrics are registered as part of the JvmMetrics like this:

JvmMetrics.builder().register();

However, if you want only the JvmClassLoadingMetrics you can also register them directly:

JvmClassLoadingMetrics.builder().register();

Example metrics being exported:

# HELP jvm_classes_currently_loaded The number of classes that are currently loaded in the JVM
# TYPE jvm_classes_currently_loaded gauge
jvm_classes_currently_loaded 1109.0
# HELP jvm_classes_loaded_total The total number of classes that have been loaded since the JVM has started execution
# TYPE jvm_classes_loaded_total counter
jvm_classes_loaded_total 1109.0
# HELP jvm_classes_unloaded_total The total number of classes that have been unloaded since the JVM has started execution
# TYPE jvm_classes_unloaded_total counter
jvm_classes_unloaded_total 0.0
