Why use this schedule
One run at the top of each hour, twenty-four a day. This is the classic maintenance cadence: frequent enough to keep data fresh, slow enough that even a heavier job finishes comfortably before the next one starts.
- Rotating or compressing logs
- Hourly aggregation of events
- Refreshing materialised views

Ready-to-use Jenkins config
Drop this into your project. The expression is the one above.
pipeline {
agent any
triggers { cron('H * * * *') }
stages {
stage('Build') { steps { echo 'Scheduled build' } }
}
}The Jenkins fields, in order: minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, 0 and 7 = Sunday).
Things to watch out for in Jenkins
- Use H instead of a fixed minute to spread load. H 2 * * * means "once during the 2 AM hour", at a stable per-job minute.
- Jenkins uses the controller's time zone. Put TZ=Asia/Kolkata on its own first line of the trigger to override it.
The common mistake with this schedule
Many teams start everything at minute 0, which creates a thundering herd on shared systems. Offset heavy jobs, for example to minute 7 or 23, or use H in Jenkins.
