Question Request to Enforce Cron Job Usage Limits

[Thomas Oryon]

Server operating system version

Rhel 9

Plesk version and microupdate number

18.0.78

Hello Support Team,

We would like to check whether the following cron job restrictions can be configured and enforced on our Plesk Linux server:

1. All cron jobs must run with nice priority level 15 or greater.
2. Cron jobs must not run more frequently than once every 15 minutes.
3. If cron jobs exceed the assigned CPU limits, the customer account should be suspended or restricted.

Please confirm whether Plesk has any built-in option to enforce these cron job limits per customer/subscription.

If this is not available by default, kindly advise the recommended method to achieve this, such as using custom scripts, systemd/cgroups, CloudLinux, or any other supported solution.

We would also like to know whether Plesk can automatically block or suspend accounts when cron jobs consume excessive CPU resources.

Awaiting your guidance.

Hi, @Thomas Oryon . There are no built-in options in Plesk that allow you to enforce all of those requirements. In terms of setting CPU limits, you can consider the Cgroup manager component or CloudLinux. However, please note that those limits are still not going to be tied to cron job CPU consumption, but overall usage.
