CP Cron (Background Jobs)
Along with the
cron scripts
that H-Sphere puts into its physical servers' crontabs,
there are several background jobs that are executed by H-Sphere on the Control Panel server:
- Accounting - does recurrent billing for end users
- OverLimitCron - checks that the account is not going over the limit
- ResellerCron - does billing for resellers
- TrialCron - suspends expired trial accounts
- RevenueCron - calculates summary billing info
- ContentMovingCron - completes the process of moving user content
- FailedSignupsCron - sends emails about failed signups (every 5 minutes)
- TTAutocloseCron - closes trouble tickets answered certain time ago
- VPSCron - queries the status of creating virtual servers (every 4 minutes)
CP Cron Configuration
H-Sphere Database
All those cron processes use the last_start table in the H-Sphere database.
This table contains the following fields:
name varchar(20) NOT NULL PRIMARY KEY,
value timestamp,
last_user int8
When H-Sphere is restarted, those values are read from this table for each cron.
Field name - CP cron job name as in the list above
Field value - last time that cron was executed
Field last_user - user_id of the last user that was calculated with the cron
(used only for accounting and overlimit).
Changing the launching time
(deprecated since HS 2.4)
Here:
TIME is the actual time in the format YYYY-MM-DD:HH:MM:SS
-05 in this example means hours of difference with GMT (Greenwich Mean Time);
GMT-05 corresponds to EST (New York).
For Central Europe, this value will be +01.
NAME is the name of the cron job.
