Default Alert Notification Hooks
Each alert rule can be configured to send notifications to one or more notification hooks. But what do you do when you want to change where all alert notifications are sent? For example, what if you had them sent to VictorOps, but your team switched from VictorOps to OpsGenie?
To make it easy to change where alert notifications are sent for the whole Sematext Cloud account, without needing to modify each and every alert rule individually, Sematext has the concept of "account default hook".
Each notification hook can be marked as "account default hook". While creating or modifying an alert rule one can choose whether to send notifications to whichever hook (or hooks!) is defined as default.
When alerts are defined to use default notification hooks then where they send notifications can be changed by simply changing which notification hooks are marked as default!
More than one notification hook can be marked as default. Which hooks are marked as default can be changed at any time. The change is instantaneous and applies to the whole account. Only alert rules that were defined to use the default notification hook(s) are affected. Any additional notification hooks specified for the alert rule will not be touched and will remain associated with the alert rule.
