Change alerts allow you to stay informed about important changes to your PostgreSQL databases, like addition or deletion of users, tables, indexes, or abrupt increases or decreases in table size, and more. While regular alerts are based on thresholds (like table size exceeding a certain limit), change alerts are based on the difference between two consecutive reports. When change alert rules are set, pgDash will check every incoming report against the previous one.
Change alerts are designed to keep you informed of any major change happening to your fleet of databases. They can catch unplanned upgrades, restores, schema modifications and rogue scripts inserting or deleting data. They can also be used to detect security concerns like creation of new users or modification of users (change of privileges, group membership).
Change alerts can be set from the pgDash UI. Notifications can be sent to email addresses, Slack channels and PagerDuty.
The Change Alerts feature is available in the Pro and Enterprise versions of pgDash SaaS and self-hosted / on-premise.
