 ### Node Schedule
 
+#### Monitor All Named Jobs
+
+Requires SDK version `11.9.0` or higher.
+
+We recommend adding `nodeScheduleIntegration`, which monitors every job created with `scheduleJob` that has a name:
+
+```JavaScript
+Sentry.init({
+  dsn: "___PUBLIC_DSN___",
+  integrations: [
+    Sentry.nodeScheduleIntegration({
+      excludeJobs: ["cleanup-temp-files", /^debug-/], // Optional.
+    }),
+  ],
+});
+```
+
+```JavaScript
+import schedule from "node-schedule";
+
+schedule.scheduleJob(
+  "daily-report",
+  { rule: "30 9 * * 1-5", tz: "Europe/Vienna" },
+  sendReport
+);
+```
+
+The monitor slug is the job name. Jobs without a name, and jobs that run once at a `Date`, aren't monitored. `excludeJobs` skips jobs whose name matches a string exactly or a regular expression.
+
+For cron strings, each check-in sends the schedule and time zone (your server's time zone if `tz` isn't set). Recurrence rules, rules with a `start` or `end`, and schedules that can't be expressed in the Crons schedule format (for example, a job that runs every 10 seconds) aren't monitored.
+
+#### Monitor Specific Jobs

 Requires SDK version `7.93.0` or higher.
 
 Use `Sentry.cron.instrumentNodeSchedule` to instrument the `schedule` export from the [`node-schedule`](https://www.npmjs.com/package/node-schedule) library. This returns an object with the same API as the original `schedule` export, but with the `scheduleJob` method instrumented. You can pass the name of the cron job as the first argument to the function. Currently this only supports cronstring as the second argument to `scheduleJob`.

+`nodeScheduleIntegration` skips jobs created with `instrumentNodeSchedule`, so using both doesn't send duplicate check-ins.
