What are default Plesk Scheduled tasks for?

Question

After Plesk Upgrade the following scripts in crontab were found:

/usr/local/psa/admin/bin/php -dauto_prepend_file=sdk.php '/usr/local/psa/admin/plib/modules/advisor/scripts/update-cache.php'
/usr/local/psa/admin/bin/php -dauto_prepend_file=sdk.php '/usr/local/psa/admin/plib/modules/wp-toolkit/scripts/instances-auto-update.php'
/usr/local/psa/admin/bin/php -dauto_prepend_file=sdk.php '/usr/local/psa/admin/plib/modules/catalog/scripts/update-index.php'
/usr/local/psa/admin/bin/php -dauto_prepend_file=sdk.php '/usr/local/psa/admin/plib/modules/wp-toolkit/scripts/maintenance.php'

What are they for? Is it safe to remove them?

Answer

It is not recommended to remove the scripts from Scheduled Tasks.

These scripts are necessary for WordPress toolkit, Plesk Advisor, and APS application catalog work.

• advisor/scripts/update-cache.php - updates the cache for Plesk Advisor
• wp-toolkit/scripts/instances-auto-update.php - takes care of WP updates
• catalog/scripts/update-index.php - updates indexes of applications in Application catalog.
• wp-toolkit/scripts/maintenance.php - performs maintenance tasks for WordPress Toolkit.
