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.

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.

RuntimeExecutionProbe

Lock-free runtime-side progress probe.

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.

CuPayloadSize

Lightweight trait to estimate the amount of data a payload will contribute when serialized. Default implementations return the stack size; specific types override to report dynamic data.

Functions

build_monitor_topology

Derive a monitor-friendly topology from the runtime configuration.

panic_payload_to_string
