ollama_log_stats

Log stats (measured economics). OPS. Aggregate the NDJSON receipts into measured economics — no model call, no egress, instant. Optional since (ISO-8601) bounds the window (‘tokens this week’). Returns {totals:{calls, tokens_in, tokens_out}, by_tool:{calls, tokens, cloud_calls, degraded_calls, p50/p95 elapsed_ms}, by_tier, backend:{cloud_calls, local_calls, degraded_calls, unrouted_calls, backend_fallback_events, fallback_rate}, tier_events:{timeouts, fallbacks}, elapsed_ms:{p50, p95}, events_scanned, log_path, log_present}. fallback_rate = degraded/(cloud-intended) — the early-warning that cloud is degrading; null when nothing intended cloud. Answers ‘cloud vs local split’, ‘fallback rate’, ‘p95 per tool’ without jq. Empty/absent log → zeros, never an error. Use ollama_log_tail for the raw events behind any number here.

Parameters

Parameter	Type	Required	Default	Description
since	string	no	—	ISO-8601 timestamp. Aggregate only events with ts >= since (e.g. ‘tokens this week’). Invalid ISO → SCHEMA_INVALID. Omit for the whole log.

Full input schema

The JSON Schema below is generated from the same zod schema the server validates against at the wire — it cannot drift from runtime behavior.

Envelope

Every tool returns the standard envelope — tier_used, model, tokens_in/tokens_out, elapsed_ms, backend provenance, warnings. See Envelope & tiers.
