Control for teams using IaC to avoid out-of-sync changes

For teams managing Alert Groups as code with the Last9 Terraform Provider, it can be useful to disable edits from the UI to avoid out-of-sync changes. Because Terraform applies are unidirectional, a team member using the UI to create or update an Alert Group or its rules can lead to drift.

Set ui_readonly = true on the last9_entity resource so edits are locked for that Alert Group only — not necessarily for every group. See the Terraform Provider docs and the Registry last9_entity schema for details.

Updates & Fixes

• By default, when an alert is no longer firing, a resolved notification is sent to the respective channel. For teams that may want to manually mark incidents as resolved, they can disable this setting from Notifications Channels.
• If you click on an alert in Alert Monitor, the timeline in the Health tab of the Alert Group will be restricted to the timestamp of the clicked alert in Alert Monitor. Earlier, the entire hour would be selected leading to display a larger set of impacted timeseries, resulting in confusion.
