Get Simulation Metrics

simulation.metrics

Read-onlyIdempotent

Read the latest metrics and resource states for a temporary anonymous demo simulation: latency, CPU, throughput, error rate, cost per hour, and per-resource health. Use it to inspect current state and metrics history without advancing time; do not use it to move the simulation forward — that is simulation.step. Responses are compact by default: principal current metrics plus explicit modeled goodputRps (a post-step point rate sourced from throughput, with provenance), goodputWindow (recorded only from persisted simulation-clock bounds, otherwise unavailable with provenance; never derive it from retrieval time or currentStep), errorBreakdown when available, per-resource status (id, name, status, cpuPercent, routedRps, availabilityState, isRoutable, and recoveryBlockedReason when provided), seeded EKS Spot checkpoint history and migrationEvaluationComplete/provenance when present, and the last 10 metrics-history entries. Pass responseMode: 'full' to get the complete simulation state, normalizedConfig, and full metrics history instead. During recovery, each resource may include recoveryProgress.state (parked, cooling_down, or healthy) with parkWindow and cooldown counters; poll simulation.step until healthy, then use simulation.metrics to inspect the resulting state and metrics. GPU / inference workflow: when the simulation includes a kubernetes resource with characteristics.inferenceMode: true, the response also includes top-level gpuUtilization (%), tokensPerSecond, costPerMillionTokens (USD/M tokens), idleGpuCostPerHour (USD/hr of standby GPU spend), and idleGpuFraction (0-1 idle HA overhead share) from the latest step, and each history entry carries the same inference fields. Pass the simulationId returned by simulation.create when your connector opens a fresh MCP session; preserve Mcp-Session-Id to use the omitted-ID current-simulation default. A fresh session has no current-simulation pointer. At least one simulation.step is needed for meaningful metrics. Read-only; repeated calls may be subject to demo usage limits. The likely next tool is simulation.step or simulation.inject_traffic.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`responseMode`	No	Response detail level. 'compact' (default) returns principal current metrics, errorBreakdown when available, per-resource status (id, name, status, cpuPercent, routedRps, availabilityState, isRoutable, recoveryBlockedReason, and failureLifecycle/routingState when provided), and only the last 10 metrics-history entries — keeps polling cheap for agent loops. 'full' returns the complete simulation object (all resource characteristics and connections) plus the entire metrics history.	compact
`simulationId`	No	Simulation ID returned by simulation.create. Preserve Mcp-Session-Id to omit this field and use the session's current simulation; if your connector starts a fresh MCP session for each call (for example Grok Bot or Cursor), pass this explicit ID after every fresh initialization. A fresh session has no current-simulation pointer and returns NO_ACTIVE_SIMULATION when the ID is omitted. Anonymous capabilities are short-lived (30 minutes by default), unguessable, and revoked when the demo expires or is deleted; proxy IP changes do not invalidate them. Do not treat the ID as a durable share link.

Output Schema

TableJSON Schema

Name	Required	Description
`metrics`	No	Metrics history — bounded to the last 10 entries in compact mode, full history in full mode
`traffic`	No	Current traffic level in RPS
`metricId`	No	Storage-assigned ID of the latest persisted metric
`appWeight`	No
`errorRate`	No	Latest client-level error rate (%) against original offered RPS. Resilience dependency targets in autoscaled compute fleets use aggregate routable-fleet capacity and health; non-autoscaled targets use their resolved resource capacity, including any declared fixed-instance count.
`resources`	No	Per-resource status summary (compact mode)
`goodputRps`	No	Modeled client-level successful requests per second; a post-step point rate sourced from metrics.throughput. Resilience dependency targets in autoscaled compute fleets use aggregate routable-fleet capacity and health; non-autoscaled targets use their resolved resource capacity, including any declared fixed-instance count.
`latencyP50`	No	Latest 50th-percentile latency in ms; null when workload-specific latency evidence is unavailable.
`latencyP95`	No	Latest 95th-percentile latency in ms; null when workload-specific latency evidence is unavailable.
`latencyP99`	No	Latest modeled 99th-percentile latency in ms; null when workload-specific latency evidence is unavailable. Interpret with latencyP99Basis and predictionEvidence.latencyP99.
`offeredRps`	No	Latest aggregate offered requests per second
`simulation`	No	Complete simulation state (full mode only; absent in compact mode and when status is not_found/access_denied)
`throughput`	No	Latest effective requests per second
`costPerHour`	No	Latest estimated cost in USD/hr
`currentStep`	No	Current simulation time step
`latencyBasis`	No	Latest general modeled latency path/boundary; see latencyP99Basis for P99-specific provenance.
`scenarioHash`	No	Canonical replay scenario graph hash.
`simulationId`	No	ID of the queried simulation
`engineVersion`	No	Simulation engine version used for this prediction.
`goodputWindow`	No	Interval goodput aggregate when every point has persisted simulation-clock bounds; otherwise status=unavailable. Never derive this from retrieval time or currentStep.
`errorBreakdown`	No	Validated additive error contributors from the latest metrics entry, in percentage-point units; distinguishes database connection pressure below the usable limit from pool saturation after exhaustion
`gpuUtilization`	No	Latest GPU utilization (%) — present only on GPU inference simulations
`modeledShedRps`	No	Latest aggregate modeled shed requests per second
`replayIdentity`	No
`auroraFailovers`	No	Latest compact per-writer Aurora failover state, with failed and standby IDs and phase.
`externalMetrics`	No	Latest deterministic external-metric recommendation telemetry, including each trigger's sample status/outcome/value/desired capacity and the combined capacity decision. It never actuates simulated or provider resources.
`idleGpuFraction`	No	Latest share (0-1) of the GPU bill that is idle/standby capacity — present only on GPU inference simulations
`latencyP99Basis`	No	Latest percentile-specific P99 basis: owned fit, scaled-from-fit (not directly measured), or uncalibrated generic model.
`tokensPerSecond`	No	Latest inference throughput in tokens/second — present only on GPU inference simulations
`goodputSemantics`	No	Goodput is a point rate, not an interval total
`kubernetesCpuHpa`	No	Latest per-workload bounded CPU HPA telemetry, including input provenance and missing-request errors; no Kubernetes controller parity is claimed.
`goodputProvenance`	No	Provenance for the modeled goodput field
`appWeightDefaulted`	No
`idleGpuCostPerHour`	No	Latest USD/hr of GPU spend funding idle/standby capacity (HA overhead) — present only on GPU inference simulations
`predictionEvidence`	No
`calibrationEvidence`	No	Owned-versus-modeled evidence and latency boundary.
`effectiveConfigHash`	No	Versioned prediction hash over replay startup inputs, engine version, and calibration identity.
`latencyAvailability`	No
`residualCostPerHour`	No	Subtotal of unavailable, parked, or stopped resource costs; healthy/degraded idle resources, including ALBs, are excluded.
`costPerMillionTokens`	No	Latest self-hosted inference cost in USD per million tokens (null when no tokens are being processed) — present only on GPU inference simulations
`eksSpotInterruptions`	No	Latest seeded EKS interruption telemetry, including additive migrationEvaluation/provenance when recorded.
`metricsHistoryLength`	No	Total number of metrics-history entries (compact mode returns only the last 10)
`resilienceDiagnostics`	No	Bounded resilience diagnostics from the latest step (compact mode). Absent when the resilience model did not run.
`residualCostDefinition`	No	Definition of residual cost; total cost remains the complete billed total.
`retryAmplificationFactor`	No	Latest (original offered RPS + generated retry RPS) / original offered RPS; an amplification measure, not capacity or goodput. Values > 1.0 = amplification risk. null = model ran but no traffic. Absent = resilience model disabled.
`predictionEffectiveConfigHash`	No	Versioned prediction hash over replay startup inputs, engine version, and calibration identity.
