Setup the cron script

After the installation, you need to configure the cron script in your servers crontab list. On most hostings you have a control panel like Direct Admin available and mostly you're able to configure cronjobs via that control panel. If you have access to there server with SSH could add the cronjob with the "crontab -e" command. Add the following line as cronjob:

php /path/to/your/modx/installation/assets/components/cronmanager/cron.php


In some cases this command needs some modifications (i.e. the path to a version specific php file). Please discuss this with your hosting provider.

The cron connector could also be called as an external webcronjob using the following url:


The value xxx has to be filled with the random string in the MODX system setting cronmanager.cronjob_id

We advise you to execute it on every minute, every day in every month (* to all: m h dom mon dow). But if you're sure, that there are no needs for an every minute cronjob, you could change the crontab interval to your own needs.

Custom Manager Page

To use the component, navigate to your manager and click on "Extras > CronManager".


You could create a new cronjob with a click on the create new cronjob button on the top left above the cronjob grid.

The grid could be filtered by the snippet name with a search input on the top right above the cronjob grid.

Each cronjob could be edited by a click on the edit icon in the row of the cronjob. The log of the cronjob could be seen with a click on the list icon in the row of the cronjob. It could be deleted after a confirmation with a click on the trash icon in the row of the cronjob.

The row of each cronjob shows the executed snippet, the minute interval, the last and the next run and the active state of an entry. The minutes and the active state could be edited inline with a double click. The last and the next run column will contain a date when the cron script is executed.


The create/edit window for one cronjob has a lot of options, that could be set.

Update Cronjob

You could set the executed snippet, the minute interval, the active state and the snippet properties. The snippet is executed on the site_start resource and it should return a json array: {"error": boolean, "message": "string"}. If not, the output will be saved in the log message and the log entry will be set to successful. The minute interval sets the interval the snippet is executed. Example: If you enter 15, the snippet would run every 15 minutes (when the cron.php file is called every minute). The snippet properties could contain key-value pairs (each on a new line in the format key: value), a JSON object or the name of a propertyset.

The snippet cannot be terminated with exit(), because the CronManager is also terminated with this exit. So it cannot write any success or error message to the database. Since version 1.2.2 CronManager: 1 is added as default snippet property to detect if the snippet is executed by CronManager. Since version 1.2.4, the current modCronjob instance can be passed as snippet property CronManagerJob to the executed snippet. This has to be enabled with the cronmanager.pass_modcronjob MODX system seetting. This way the snippet can determine, which job triggered it, it can change and save the modCronjob instance to i.e. disable the cron job.


After adding a cronjob, it isn't active. You have to change the active state to yes in the Active column of the overview or check the checkbox in the edit window.
