# Timeline
The **Timeline** tab from **Device View** presents data and events—that span a period of up to 30 days—in a structured manner, encompassing various sections.
{% hint style="info" %}
The timeline color conventions facilitate spotting issues. Events in red are a quick indicator of underperforming metrics and problems.
{% endhint %}
Explore the **Timeline** main sections with the chronological device events:
| **Alerts and errors**: alert events, error events, freeze events. |
| ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
Device performance (5-minute intervals): CPU, memory usage, system drive space, GPU usage, NPU and disk performance.
The NPU metric is currently available only for devices running Windows.
Memory metrics vary by operating system:
Windows → Usage (% of total RAM in use)
macOS → Pressure (% system memory load).
macOS memory pressure requires Collector version 25.8 or higher.
|
| **Connectivity**: Wi-Fi and Ethernet (5-minute intervals), connections, network applications and connectivity applications (15-minute intervals). |
| **Collaboration:** Microsoft Teams, Zoom calls and any applications configured under the Collaboration category. |
| **Activity**: system boots, remote actions, installation and uninstallation of packages and Windows services, configuration changes, Microsoft Teams and Zoom calls (duration of the call). |
| **Applications** (15-minute intervals): network, desktop and web application usage and events—refer to the [Getting started with Applications](/platform/user-guide/applications/getting-started-with-applications.md) documentation for more information about application type. |
| **User interaction** (5-minute intervals): user interaction, login, logout, locks, unlocks, virtual session events such as Citrix RTT and session network latency. |
| **Workflow executions** (15-minute intervals): workflows and remote actions. |
## Zooming in and out of the timeline
To zoom in on a specific section of the timeline from the Device View page, choose one of these options:
* Click on the zoom-in or zoom-out buttons to load up to 48 hours of data into the timeline.
* Drag your cursor along the timeline to select the desired timeframe. Narrow the data down to a six-hour timeframe.
Click on the home buttons to adjust the timeline to the events of the *device's last seen date and time*, i.e., the date and time of the last device activity received by the Nexthink instance.
## Drilling down to specific events in the timeline
1. Hover over a specific event to display its information details.
* For **CPU** and **Memory usage**, when relevant, the pop-over shows the high-usage binaries associated with that metric.
* Both the pop-over and the right-side panel visually indicate, with colored icons, the underperforming metrics contributing to the device issue.
2. Click on a specific event to display the selected information details in the right-side panel within the device icon.
* The information includes device performance, connectivity, activities, application usage, and links to relevant dashboards and **Suggested investigations**.
{% hint style="info" %}
Additionally, the **Actions** icon in the right-side panel allows you to take associated actions from the Device View page on the target device, depending on the user [role](/platform/user-guide/device-view.md#deviceview-requiredpermissionsfordeviceview) permissions.
{% endhint %}
{% hint style="info" %}
Refer to the [Using Device View for call quality issues](/platform/user-guide/collaboration-experience/using-device-view-for-call-quality-issues.md) documentation to leverage the Timeline tab for troubleshooting collaboration tools.
{% endhint %}
### Obtaining binary descriptions from the Timeline side panel
From the [Timeline](/platform/user-guide/device-view/timeline.md) side panel, hover over any binary name to obtain an AI-generated description.
These binary descriptions attempt to attribute a category and subcategory to the binary, providing additional context related to functionality.
{% hint style="info" %}
The system displays the ✦ sparkles icon to indicate AI-generated content or insights. AI is evolving rapidly and delivering great insights, but it can still make mistakes. Nexthink recommends validating your results to ensure accuracy and support informed decision-making.
Refer to the [Nexthink Insights - AI Model Card](https://docs.nexthink.com/legal/global-ai-hub/nexthink-insights-ai-model-card) documentation for more information.
