Metric Set: jvm_memory_pool_allocated_bytes
Number of bytes of memory allocated in a specific memory pool in the Java Virtual Machine (JVM). In Pulsar, this typically refers to the amount of memory allocated for various purposes in the JVM (such as heap memory, non-heap memory, etc.).
Metric Set: jvm_memory_pool_used_bytes
Unlike allocated_bytes, this metric shows the actual used memory, not just the allocated memory.
Metric Set: jvm_memory_pool_committed_bytes
Number of bytes of memory committed in a specific memory pool in the JVM. In the JVM, committed memory is the amount of memory guaranteed to be available for the application to use. This portion of memory is typically locked by the operating system to reduce swapping or garbage collection.
Metric Set: jvm_memory_pool_max_bytes
Maximum number of bytes of memory that can be allocated in a specific memory pool in the JVM. This is the upper limit on memory usage for that memory pool and helps in setting the memory usage cap.
Metric Set: pulsar_broker_publish_latency
Message publishing latency on the broker side.
Metric Set: pulsar_metadata_store_ops_latency_ms
Latency of metadata store operations on the broker side.
