Repeat Notification Interval

Control how often Last9 re-notifies your channels while an alert stays firing. You can set a custom interval, cap the number of reminders, or turn off repeats entirely (notify-once) — at both the organization level and per alert group.

Settings

There are three fields:

Two Levels of Configuration

Organization-wide defaults

Set defaults that apply to all alert groups unless overridden.

1. Navigate to Alerting → Notification Settings
2. Enable Override defaults to unlock the fields
3. Configure Repeat while firing, Repeat interval, and Maximum repeats
4. Click Save

Per alert group

Override the org defaults for a specific alert group.

1. Navigate to Alerting → Alert Groups → select an alert group
2. Click the ⚙️ icon → Settings → Notifications → Settings tab
3. Enable Override defaults to unlock per-group values
4. Configure the fields and click Save

Common Configurations

Notify-once — one notification per firing episode, no reminders:

• Turn off Repeat while firing

Custom interval, unlimited repeats — re-notify every 30 minutes forever:

• Keep Repeat while firing on
• Set Repeat interval to 1800
• Set Maximum repeats to -1

Capped reminders — re-notify every hour, stop after 3 reminders:

• Keep Repeat while firing on
• Set Repeat interval to 3600
• Set Maximum repeats to 3

Via Terraform

Configure renotify settings on a last9_entity resource using the three optional fields. Omit all three to inherit the org default.

Notify-once — suppress all repeat notifications:

resource "last9_entity" "api" {
  name         = "api-service"
  type         = "service"
  entity_class = "alert-manager"
  external_ref = "api-service-prod"

  renotify_enabled = false
}

Custom interval with a cap:

resource "last9_entity" "api" {
  name         = "api-service"
  type         = "service"
  entity_class = "alert-manager"
  external_ref = "api-service-prod"

  renotify_enabled          = true
  renotify_interval_seconds = 1800  # every 30 minutes
  renotify_occurrences      = 3     # stop after 3 repeats
}

Unlimited repeats — re-notify forever at a custom interval:

  renotify_enabled          = true
  renotify_interval_seconds = 3600
  renotify_occurrences      = -1

To reset a group back to org defaults, remove all three renotify_* fields and run terraform apply.

Default Behavior

If you don’t override, the system default applies: Repeat while firing on, interval 3600 seconds, no cap.

Existing alert groups are unaffected unless you explicitly change settings.

Notes

• Settings apply to all notification channels (Slack, email, webhook, PagerDuty, OpsGenie, Flock, GoAlert)
• Per-group settings take precedence over org-wide defaults when Override defaults is on
• A new firing episode (resolved → fires again) resets the repeat counter
• SLO alerts: The repeat interval for SLO alerts is derived from the SLO window and is not configurable via this setting. The org/group settings apply to threshold and anomaly alert groups only.
