ollama_log_tail

Tail NDJSON log. OPS. Structured tail of the NDJSON observability log at ~/.ollama-intern/log.ndjson (override via INTERN_LOG_PATH). No model call. Optional filters: limit (default 50, max 500), filter_kind (‘call’ | ‘timeout’ | ‘fallback’ | ‘guardrail’ | ‘pack_step’ | ‘semaphore:wait’ | ‘prewarm’ | ‘prewarm:in_progress_request’), filter_tool, since (ISO-8601). Truncated final lines are skipped silently. Missing log file is a soft-empty case, not an error. Returns {events, total_returned, log_path, log_present}. Use this to debug why a call was slow / what timed out / what the last failures were.

Parameters

Parameter	Type	Required	Default	Description
limit	integer	no	—	Max events to return (newest first). Default 50, cap 500.
filter_kind	string	no	—	Keep only events with this kind — e.g. ‘call’, ‘timeout’, ‘fallback’, ‘backend_fallback’ (cloud→local), ‘pack_step’, ‘semaphore:wait’.
filter_tool	string	no	—	Keep only events whose tool matches — e.g. ‘ollama_research’.
since	string	no	—	ISO-8601 timestamp. Keep only events with ts >= since. Invalid ISO → SCHEMA_INVALID.

Envelope

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