nulog
Logging + metrics as a Nu app. Append-only logs and kh57-backed metric series
kept in nu.kv, written and read in Nu. Every write is a Nu Command; every
read is a Nu Query.
Usage
Everything happens inside a nulog.store(...) bracket. Writes are Nu
Commands, reads are Nu Queries that yield list[dict] or dict[str, int].
import nu, nulog
tree = nu.With(nulog.store(),
body=nu.kv.Transaction(
nulog.info("app", "server started", port=8080)
>> nulog.warn("app", "cache miss", key="user:42")
>> nulog.error("app", "request failed", path="/checkout", code=500)
>> nulog.observe("cpu_load", 0.42)
)
>> nu.kv.Snapshot(nu.print("tail:", nulog.tail("app", 3)))
>> nu.kv.Snapshot(nu.print("errors:", nulog.errors("app")))
>> nu.kv.Snapshot(nu.print("count:", nulog.count_by_level("app"))),
)
nu.run(tree)
Read atoms cover the search space:
- Logs:
tail(stream, n),head(stream, n),by_level(stream, level),errors(stream),since(stream, ts_us),between(stream, start_us, end_us),search(stream, text),count_by_level(stream). - Metrics:
range_metric(name, begin, end),sample_metric(name, n, begin, end).
Rows come out as plain dicts. Log rows:
{"key": int, "ts_us": int, "level": str, "msg": str, "fields": dict}.
Metric rows: {"ts_us": int, "ts": float, "value": float}.
UI
The viewer is a bracket too: nulog.ui(streams, port=) boots a nudle server
under nulog.store(...). Same shape as any Nu-nudle app.
import asyncio, nu, nulog
tree = nu.With(
nulog.store("logs.db"),
nulog.ui(["app", "scraper"], port=8080),
body=nulog.info("app", "server started")
>> nu.ForeverDo(
nu.kv.Transaction(nulog.info("app", "tick")) >> nu.Delay(1.5)
),
)
asyncio.run(nu.arun(tree))
Open http://127.0.0.1:8080: live newest-first entry table, stream switcher, level filter, message search, per-level count stats. The table + counts repaint every second off the same read atoms above.
