'jvm.cpu.count'

JVM_CPU_RECENT_UTILIZATION =

Note:

Stability Level: stable

Recent CPU utilization for the process as reported by the JVM.

The value range is [0.0,1.0]. This utilization is not defined as being for the specific interval since last measurement (unlike system.cpu.utilization). Reference.

'jvm.cpu.recent_utilization'

JVM_CPU_TIME =

Note:

Stability Level: stable

'jvm.gc.duration'

JVM_MEMORY_COMMITTED =

Note:

Stability Level: stable

Measure of memory committed.

'jvm.memory.committed'

JVM_MEMORY_LIMIT =

Note:

Stability Level: stable

Measure of max obtainable memory.

'jvm.memory.limit'

JVM_MEMORY_USED =

Note:

Stability Level: stable

Measure of memory used.

'jvm.memory.used'

JVM_MEMORY_USED_AFTER_LAST_GC =

Note:

Stability Level: stable

Measure of memory used, as measured after the most recent garbage collection event on this pool.

'jvm.memory.used_after_last_gc'

JVM_THREAD_COUNT =

Note:

Stability Level: stable

Number of executing platform threads.

'jvm.thread.count'

Attribute Names

JVM_GC_ACTION =

end of major GC

'jvm.gc.action'

JVM_GC_NAME =

Note:

Stability Level: stable

Name of the garbage collector.

Garbage collector name is generally obtained via GarbageCollectionNotificationInfo#getGcName().

Examples:

Sample Values

G1 Young Generation
G1 Old Generation

'jvm.gc.name'

JVM_MEMORY_POOL_NAME =

'jvm.thread.daemon'

JVM_THREAD_STATE =

Note:

Stability Level: stable

State of the thread.

Examples:

Sample Values
