Module monitoring 

Some basic internal monitoring tooling Copper uses to monitor itself and the components it runs.

Structs

ComponentId

Strongly-typed index into CuMonitoringMetadata::components.

CopperListEntry

One message entry in CopperList slot order with resolved component identity.

CopperListInfo

CopperListIoStats

Reported data about CopperList IO for a single iteration.

CopperListLayout

Static monitor-side CopperList indexing layout.

CopperListView

Per-loop monitor view over CopperList metadata paired with static component mapping.

CountingAlloc

A simple allocator that counts the number of bytes allocated and deallocated.

CuDurationStatistics

A Specialized statistics object for CuDuration. It will also keep track of the jitter between the values.

CuListSlot

Strongly-typed CopperList slot index.

CuMonitoringMetadata

Immutable runtime-provided metadata passed once to CuMonitor::new.

CuMonitoringRuntime

Runtime-provided dynamic monitoring handles passed once to CuMonitor::new.

CuMsgIoCache

CuMsgIoCaptureGuard

CuMsgIoStats

ExecutionMarker

Execution progress marker emitted by the runtime before running a component step.

LiveStatistics

Accumulative stat object that can give your some real time statistics. Uses a fixed-size bucketed histogram for accurate percentile calculations.

MonitorComponentMetadata

Static identity entry for one monitored runtime component.

MonitorConnection

MonitorExecutionProbe

Platform-neutral monitor view of runtime execution progress.

MonitorNode

MonitorTopology

NoMonitor

A do nothing monitor if no monitor is provided. This is basically defining the default behavior of Copper in case of error.

PanicHookRegistration

PanicReport

PayloadIoStats

RuntimeExecutionProbe

Lock-free runtime-side progress probe.

ScopedAllocCounter

Scoped helper that captures the calling thread’s allocation counters on construction and exposes the delta accumulated by the time you query it.

Enums

ComponentType

Runtime component category used by monitoring metadata and topology.

CuComponentState

Lifecycle state of a monitored component.

Decision

Monitor decision to be taken when a component step errored out.

Traits

CuMonitor

Runtime monitoring contract implemented by monitor components.

Functions

build_monitor_topology

Derive a monitor-friendly topology from the runtime configuration.

global_allocated_bytes

Total bytes ever allocated through the CountingAlloc global allocator.

global_deallocated_bytes

Total bytes ever returned to the CountingAlloc global allocator.

panic_payload_to_string

payload_io_stats

Measures payload bytes using the same encode path Copper uses for logging/export.

runtime_panic_hook_active

start_copperlist_io_capture

take_last_completed_handle_bytes
