[Skip to content](#%5Ftop) # Device monitoring Monitor performance and network status for your organization's [fleet](https://developers.cloudflare.com/cloudflare-one/insights/dex/monitoring/#fleet-status) (all devices with the Cloudflare One Client installed and connected to your Zero Trust organization) or individual [user devices](https://developers.cloudflare.com/cloudflare-one/insights/dex/monitoring/#device-monitoring). Network and device performance data helps IT administrators troubleshoot performance issues, investigate network connectivity problems, and monitor device health. ## Device overview A fleet is a collection of user devices. All devices in a fleet have the Cloudflare One Client installed and are connected to a [Cloudflare Zero Trust organization](https://developers.cloudflare.com/cloudflare-one/setup/#2-create-a-zero-trust-organization). To view fleet status: 1. In [Cloudflare One ↗](https://one.dash.cloudflare.com/), go to **Insights** \> **Digital experience**. 2. Review the information under **Live analytics**. ### View metrics The **Device overview** tab shows real-time and historical connectivity metrics for all devices in your organization. To view analytics on a per-device level, go to [Device monitoring](https://developers.cloudflare.com/cloudflare-one/insights/dex/monitoring/#device-monitoring). ### Available metrics * **Devices connected by colo**: Number of devices connected to a given [Cloudflare data center ↗](https://www.cloudflarestatus.com/). * **Connectivity status**: Percentage of devices in a given Cloudflare One Client state. | Status | Description | | ------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Connected | The Cloudflare One Client has successfully established a connection to the Cloudflare global network. | | Disconnected | The Cloudflare One Client has been intentionally or unintentionally disconnected from the Cloudflare global network. | | Paused | A user or administrator has taken an explicit action to temporarily turn off WARP, for example by entering an [admin override code](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/cloudflare-one-client/configure/settings/#allow-admin-override-codes). Paused clients will [auto-connect](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/cloudflare-one-client/configure/settings/#auto-connect) after a timeout period. | | Connecting | The Cloudflare One Client is pending connection, but is actively trying to establish a connection to the Cloudflare global network. | * **Mode**: [Client mode](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/cloudflare-one-client/configure/modes/) deployed on the device. * **Colo**: Percentage of devices connected to a given Cloudflare data center. * **Platform**: Operating system of the device. * **Major Version**: Cloudflare One Client version installed on the device. * **Device Status Over Time**: Cloudflare One Client connection status over the selected time period. * **Connection Methods Over Time**: Client mode used by the device over the selected time period. ## Device monitoring Review network and device performance for a device enrolled in your fleet. ### View a device's performance To view a device's network and device performance metrics: 1. In [Cloudflare One ↗](https://one.dash.cloudflare.com/), go to **Team & Resources** \> **Devices** \> **Your devices**. 2. Select a device > **View details**. 3. Select the **DEX** tab. 4. In **Device Monitoring**, scroll down to **Network performance** and **Device Performance**. ### Network and device performance metrics #### Network performance metrics * **Unique networks over time**: How many unique SSIDs (Wi-Fi network names) the device was connected to. * **Network I/O**: How much data the device transferred (uploads and downloads) over the primary network interface. #### Device performance metrics * **Battery percentage and cycles**: Displays battery percentage and [battery cycles ↗](https://support.apple.com/en-us/102888) over time. Use this metric to debug potential performance issues possibly related to battery health or power-saving measures that trigger at low-battery levels. * **CPU usage**: CPU utilization over time. Use this metric to debug slow system performance due to high CPU usage. * **Memory utilization**: Memory utilization over time. Use this metric to debug performance issues related to an overtaxed memory. * **Disk I/O**: Displays number of disk read/write operations over time. Use this metric to debug performance errors due to heavy disk operations. ## Export DEX device state event logs The log data for all [DEX device state events](https://developers.cloudflare.com/logs/logpush/logpush-job/datasets/account/dex%5Fdevice%5Fstate%5Fevents/) can be exported to [R2](https://developers.cloudflare.com/r2/), a cloud bucket, or a SIEM via [Logpush](https://developers.cloudflare.com/cloudflare-one/insights/logs/logpush/). ```json {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/directory/","name":"Directory"}},{"@type":"ListItem","position":2,"item":{"@id":"/cloudflare-one/","name":"Cloudflare One"}},{"@type":"ListItem","position":3,"item":{"@id":"/cloudflare-one/insights/","name":"Insights"}},{"@type":"ListItem","position":4,"item":{"@id":"/cloudflare-one/insights/dex/","name":"Digital experience"}},{"@type":"ListItem","position":5,"item":{"@id":"/cloudflare-one/insights/dex/monitoring/","name":"Device monitoring"}}]} ```
