## Search your devices
26
+
You can use the following tools in your IoT Central application:
27
+
28
+
- The **Devices** page lets you monitor and manage individual devices.
29
+
- The **Device groups** and **Data explorer** pages let you monitor aggregate data from your devices.
30
+
- The **Jobs** page lets you manage your devices in bulk.
31
+
- Custom dashboards let you manage and monitor devices in a way that suits you.
32
+
- The REST API and Azure CLI enable you to automate device management tasks.

IoT Central lets you search devices by device name, ID, property value or cloud property value.

45
+
46
+
## Group your devices
47
+
48
+
On the **Device groups** page, you can use queries to define groups of devices. You can use device groups to:
49
+
50
+
- Monitor aggregate data from devices on the **Device explorer** page.
51
+
- Manage groups of devices in bulk by using jobs.
52
+
- Control access to groups of devices if your application uses organizations.
53
+
54
+
To learn more, see [Tutorial: Use device groups to analyze device telemetry](tutorial-use-device-groups.md).
35
55
36
-
To monitor devices, use the custom device views defined by a solution builder. These views can show device telemetry and property values. An example is the **Overview** view shown in the previous screenshot.

## Manage your devices
37
57
38
-
For more detailed information, use device groups and the built-in analytics features. To learn more, see [How to use data explorer to analyze device data](howto-create-analytics.md).
58
+
Use the **Devices** page to manage individual devices connected to your application:
39
59
40
-
To manage individual devices, use device views to set device and cloud properties, and call device commands. Examples include the **Manage device** and **Commands** views in the previous screenshot.

+
:::image type="content" source="media/overview-iot-central-operator/device-management-options.png" alt-text="Screenshot showing the device management options.":::
41
61
42
-
To manage devices in bulk, create and schedule jobs. Jobs can update properties and run commands on multiple devices. To learn more, see [Create and run a job in your Azure IoT Central application](howto-manage-devices-in-bulk.md).
62
+
For individual device, you can complete tasks such as [block or unblock it](howto-manage-devices-individually.md#device-status-values), [attach it to a gateway](tutorial-define-gateway-device-type.md), [approve it](howto-manage-devices-individually.md#device-status-values), [migrate it to a new device template](howto-edit-device-template.md#migrate-a-device-across-versions), [associate it with an organization](howto-create-organizations.md), and [generate a map to transform the incoming telemetry and properties](howto-map-data.md).
63
+
64
+
You can also set writable properties and cloud properties that are defined in the device template, and call commands on the device.
43
65
44
66
To manage IoT Edge devices, you can use the IoT Central UI to[create and edit deployment manifests](concepts-iot-edge.md#iot-edge-deployment-manifests-and-iot-central-device-templates), and then deploy them to your IoT Edge devices. You can also run commands in IoT Edge modules from within IoT Central.

-
If your IoT Central application uses *organizations*, an administrator controls which devices you have access to.
68
+
Use the **Jobs** page to manage your devices in bulk. Jobs can update properties and run commands on multiple devices. To learn more, see [Manage devices in bulk in your Azure IoT Central application](howto-manage-devices-in-bulk.md).

The [troubleshooting guide](troubleshoot-connection.md) helps you to diagnose and remediate common issues. You can use the **Devices** page to block devices that appear to be malfunctioning until the problem is resolved.
73
+
## Monitor your devices
74
+
75
+
To monitor individual devices, use the custom device views on the **Devices** page. A solution builder defines these custom views as part of the [device template](concepts-device-templates.md). These views can show device telemetry and property values. An example is the **Overview** view shown in the following screenshot:

## Add and remove devices
79
+
To monitor aggregate data from multiple devices, use device groups and the **Data explorer** page. To learn more, see [How to use data explorer to analyze device data](howto-create-analytics.md).
53
80
54
-
You can add and remove devices in your IoT Central application either individually or in bulk. To learn more, see:

-
-[Manage individual devices in your Azure IoT Central application](howto-manage-devices-individually.md).
57
-
-[Manage devices in bulk in your Azure IoT Central application](howto-manage-devices-in-bulk.md).
83
+
You can further customize the device management and monitoring experience using the following tools:
58
84
59
-
## Personalize
85
+
- Create more views to display on the **Devices** page for individual devices by adding view definitions to your [device templates](concepts-device-templates.md).
86
+
- Customize the text that describes your devices in the application. To learn more, see [Change application text](howto-customize-ui.md#change-application-text).
87
+
- Create [custom device management dashboards](howto-manage-dashboards.md). A dashboard can include a [pinned query](howto-manage-dashboards.md#pin-analytics-to-dashboard) from the **Data explorer**.
60
88
61
-
Create personal dashboards in an IoT Central application that contain links to the resources you use most often. To learn more, see [Manage dashboards](howto-manage-dashboards.md).
89
+
## Automate
90
+
91
+
To automate device management tasks, you can use:
92
+
93
+
- Rules to trigger actions automatically when device data that you're monitoring reaches predefined thresholds. To learn more, see [Configure rules](howto-configure-rules.md).
94
+
-[Job scheduling](howto-manage-devices-in-bulk.md#create-and-run-a-job) for regular device management tasks.
95
+
- The Azure CLI to manage your devices from a scripting environment. To learn more, see [az iot central](/cli/azure/iot/central).
96
+
- The IoT Central REST API to manage your devices programmatically. To learn more, see [How to use the IoT Central REST API to manage devices](howto-manage-devices-with-rest-api.md).
