+# Monitoring
+
+This module adds monitoring of workspace resources.
+
+```tf
+module "monitoring" {
+  source  = "registry.coder.com/modules/monitoring/coder"
+  version = "1.0.0"
+  agent_id = coder_agent.dev.id
+}
+```
+
+## Examples
+
+```tf
+module "monitoring" {
+  source  = "registry.coder.com/modules/monitoring/coder"
+  version = "1.0.0"
+  agent_id = coder_agent.dev.id
+}
+```
+
+### Enable/Disable
+
+You can customize the monitoring by setting the `enabled`, `memory_enabled`, and `disk_enabled` variables.
+
+```tf
+module "monitoring" {
+  source  = "registry.coder.com/modules/monitoring/coder"
+  version = "1.0.0"
+  agent_id = coder_agent.dev.id
+  enabled = false
+  memory_enabled = true
+  disk_enabled = false
+}
+```
+
+### Customize Thresholds
+
+You can customize the thresholds by setting the `threshold`, `memory_threshold`, and `disk_threshold` variables.
+
+```tf
+module "monitoring" {
+  source  = "registry.coder.com/modules/monitoring/coder"
+  version = "1.0.0"
+  agent_id = coder_agent.dev.id
+  threshold = 90
+  memory_threshold = 95
+  disk_threshold = 90
+}
+```
+
+### Customize Disks
+
+You can customize the disks by setting the `disks` variable.
+
+```tf
+module "monitoring" {
+  source  = "registry.coder.com/modules/monitoring/coder"
+  version = "1.0.0"
+  agent_id = coder_agent.dev.id
+  disks = ["/"]
+}
+```
