# Timeline

The **Timeline** tab presents data and events that span a period of up to 30 days in various sections.

{% hint style="info" %}
The timeline color conventions facilitate spotting issues. Events in <mark style="color:red;">red</mark> are a quick indicator of underperforming metrics and problems.
{% endhint %}

The following sections explain which chronological device events are shown in each category.

### Alerts and errors

Shows alert events, error events, freeze events.

### Device performance

Shows CPU, memory usage, system drive space, GPU usage, NPU, and disk performance. Events are shown in 5-minute intervals.

* Thresholds for **Device Performance** metrics align with DEX score thresholds. Refer to [Device view timeline metric thresholds](https://edocs.nexthink.com/nexthink-infinity/infinity-specifications/device-view-timeline-metric-thresholds).
* The **NPU** metric are available only for devices running Windows.

#### CPU

By default, the timeline shows the normalized CPU usage:

Select an event on the timeline to drill down to it. The timeline drill down panel opens on the right side, where you can select the metrics and binaries that contribute to the CPU usage.

Here you can:

* Select the metrics, such as **CPU queue lenght**, to open up the metric-specific timeline.
* Select the binaries to add their specific chart to the to the **Normalized CPU usage** timeline.

#### Memory

By default, timeline shows overall memory usage:

<figure><img src="/files/kEYeGwrcpT4Q2S5p9o9N" alt=""><figcaption></figcaption></figure>

Select an event on the timeline to drill down to it. The timeline drill down panel opens on the right side, where you can see detailed metrics about the memory usage.

For Windows devices, two separate timelines open up for **Memory swap rate** and **Disk queue length**:

For macOS devices, two separate timelines open up for **Memory pressure** and **Memory swap rate**:

{% hint style="info" %}
Memory pressure for macOS requires Collector version 25.8 or higher.
{% endhint %}

### Connectivity

Shows Wi-Fi and ethernet in 5-minute intervals. Furthermore shows connections, network applications, and connectivity applications in 15-minute intervals.

### Collaboration

Shows Microsoft Teams, Zoom calls and any applications configured under the Collaboration category.

### Activity

Shows system boots, remote actions, installation and uninstallation of packages and Windows services, configuration changes, Microsoft Teams and Zoom calls (duration of the call).

### Applications

Shows network, desktop and web application usage and events in 15-minute intervals. 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

Shows user interaction, login, logout, locks, unlocks, virtual session events such as Citrix RTT and session network latency in 5-minute intervals.

### Workflow executions

Shows workflows and remote actions in 15-minute intervals.

## Zooming in and out of the timeline <a href="#timeline-zoominginandoutofthetimeline" id="timeline-zoominginandoutofthetimeline"></a>

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 <a href="#timeline-drillingdowntospecificeventsinthetimeline" id="timeline-drillingdowntospecificeventsinthetimeline"></a>

1. Hover over a specific event to display its information details. Both the pop-over and the right-side panel visually indicate, with colored icons, the underperforming metrics contributing to the device issue.
2. Select 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 %}

<figure><img src="/files/Kcx77W5qCvRPHZI6ML8n" alt="Drilling down to specific events in the timeline"><figcaption></figcaption></figure>

{% 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 <a href="#table-tablespecificfields" id="table-tablespecificfields"></a>

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.

<figure><img src="/files/4FUwLtClSXokwc6EAl9W" alt=""><figcaption></figcaption></figure>

{% 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.
