## Sentinels

<AccordionGroup>
  <Accordion title="What are sentinels?">
    24/7 automated monitors on engineer performance, customer risk, SLA clusters, and commercial signals. They run immediately against your full job history from day one — no warm-up period, no waiting for data to accumulate. They alert when thresholds are breached, not on every minor fluctuation, keeping the noise low and the signal meaningful.
  </Accordion>

  <Accordion title="Will sentinels replace my ops manager?">
    Sentinels prioritise attention. They give the ops manager a daily or weekly list of the patterns that merit human review, so the team can spend less time scanning jobs and more time deciding what to do.
  </Accordion>

  <Accordion title="How are false positives handled?">
    Thresholds are calibrated during onboarding to minimise noise. You can tune sensitivity per sentinel and apply exclusions for training roles, contractors, or entities that are not relevant to a particular signal.
  </Accordion>

  <Accordion title="What severity levels exist?">
    | Level    | Meaning                 | Suggested action |
    | -------- | ----------------------- | ---------------- |
    | Critical | Significant risk        | Same-day review  |
    | Warning  | Negative trend          | Within 48 hours  |
    | Info     | Heads-up or opportunity | Weekly digest    |

    Severity levels are fully configurable per sentinel. The consistency of levels is what enables deterministic, programmatic actions downstream: automations route Critical alerts to Slack immediately, open a case, or notify an account manager, all based on severity alone. Sentinels also monitor their own threshold performance and suggest adjustments when a setting is generating too much noise or missing signals.

  <Accordion title="Do alerts include reference IDs so I can act in BigChange?">
    Yes. Customer-oriented alerts include the customer name and reference so you can look up the account in BigChange immediately.
