+### Configure OOM/OOD notifications
+
+You can monitor out of memory (OOM) and out of disk (OOD) errors and alert users
+when they overutilize memory and disk.
+
+This can help prevent agent disconnects due to OOM/OOD issues.
+
+To enable OOM/OOD notifications on a template, follow the steps in the
+[resource monitoring guide](../../templates/extending-templates/resource-monitoring.md).

+# Resource monitoring
+
+Use the
+[`resources_monitoring`](https://registry.terraform.io/providers/coder/coder/latest/docs/resources/agent#resources_monitoring-1)
+block on the
+[`coder_agent`](https://registry.terraform.io/providers/coder/coder/latest/docs/resources/agent)
+resource in our Terraform provider to monitor out of memory (OOM) and out of
+disk (OOD) errors and alert users when they overutilize memory and disk.
+
+This can help prevent agent disconnects due to OOM/OOD issues.
+
+You can specify one or more volumes to monitor for OOD alerts.
+OOM alerts are reported per-agent.
+
+## Prerequisites
+
+Notifications are sent through SMTP.
+Configure Coder to [use an SMTP server](../../monitoring/notifications/index.md#smtp-email).
+
+## Example
+
+Add the following example to the template's `main.tf`.
+Change the `90`, `80`, and `95` to a threshold that's more appropriate for your
+deployment:
+
+```hcl
+resource "coder_agent" "main" {
+  arch = data.coder_provisioner.dev.arch
+  os   = data.coder_provisioner.dev.os
+  resources_monitoring {
+    memory {
+      enabled   = true
+      threshold = 90
+    }
+    volume {
+      path      = "/volume1"
+      enabled   = true
+      threshold = 80
