Question Request for Guidance on Cron Job Restrictions in Plesk Linux

[Thomas Oryon]

Server operating system version

RHEL 9

Plesk version and microupdate number

18.0.78

Hello Support Team,

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

1. All cron jobs should run with a nice priority level of 15 or higher.
2. Cron jobs should not be allowed to run more frequently than once every 15 minutes.
3. If a cron job exceeds the assigned CPU limits, the respective customer account should be suspended or restricted.

Could you please confirm whether Plesk provides any built-in option to enforce these cron job limits per customer or subscription?

If this is not available by default, kindly advise the recommended approach to achieve this, such as using custom scripts, systemd/cgroups?

Additionally, please confirm whether Plesk can automatically block, restrict, or suspend customer accounts when cron jobs consume excessive CPU resources.

We look forward to your guidance.
