Monitor cron-job health in Postgres

Hear about the scheduled jobs that fail or run long — and only those — so a silent backup or a stalled sync becomes a message, not a surprise.

the event

You emit cron.finished with this shape. The TypeScript SDK keeps the call type-safe, and the event is stored whole — so every field below is available to the pipeline by name.

  • jobstringjob name
  • statusstringok | failed
  • duration_msnumber
  • expected_msnumbertypical runtime
  • exit_codenumber

emit it

From your code with the TypeScript SDK — or any language over the REST endpoint and signed webhook ingress.

emit cron.finished
import { ingest } from "@ingestlayer/sdk";

await ingest("cron.finished", {
  job:         "nightly-backup",
  status:      ok ? "ok" : "failed",
  duration_ms: Date.now() - startedAt,
  expected_ms: 120000,
  exit_code:   code,
});

route it to Postgres

Insert each event as a row into a table in your own Postgres.

  1. 01

    add the connection

    Paste a Postgres connection string. Connections originate from our EU region — allowlist those egress IPs on your database.

  2. 02

    point at a table

    Name the target table. Top-level event fields map to columns, and the full payload is also available as a jsonb column.

  3. 03

    map columns

    Match event fields to columns with $event.* references, or accept the default mapping into a typed events table.

in postgresdelivered
INSERT INTO events.signups
  (user_id, email, plan, source, payload)
VALUES
  ('u_018f', 'ada@acme.com', 'pro',
   'marketing-site', '{ … }'::jsonb);

notes

questions

Can I only hear about problems?
Filter to failures and jobs that overran their expected_ms; healthy runs pass silently to the warehouse for the record.
How do I catch a job that never ran?
Pair this with a scheduled check that emits when an expected cron.finished is missing — absence is the signal there.
Can different jobs alert different teams?
Branch on the job name so a failed billing run reaches finance and a failed deploy reaches engineering.
