# Using Sessions overview

The **Sessions overview** dashboard allows you to gain insights into all Virtual Desktop Infrastructure (VDI) sessions in your organization. The top-to-bottom arrangement of widgets provides an intuitive solution to quickly identify problematic sessions in your entire virtual infrastructure, giving you the ability to gradually locate the root cause by identifying issue patterns that have developed over time. This progressive approach provides you with all the relevant data needed for effective troubleshooting without overwhelming you with irrelevant information.

## Sessions overview tabs

The following tabs are available in the Sessions overview dashboard. Refer to each section for explanation of the components and functionalities of each tab.

* [Sessions tab](/platform/user-guide/vdi-experience/using-sessions-overview/sessions.md) displays metrics and per-session trends for all VDI sessions to identify issue patterns.
* [Session map tab](/platform/user-guide/vdi-experience/using-sessions-overview/sessions-1.md) displays an overview of connections between the endpoint devices and VMs.
* [Executions tab](/platform/user-guide/vdi-experience/using-sessions-overview/sessions-2.md) displays a list of all executions on the VMs in all active sessions.
* [Connections tab](/platform/user-guide/vdi-experience/using-sessions-overview/sessions-3.md) displays an overview of connections between the VMs and backend systems in all sessions.

## Using filters

Use filters at the top of the dashboard to analyze sessions based on the topology of your environment. Active filters affect all widgets on the dashboard, meaning that only sessions that fall within the scope of every active filter are visible in the widgets, including [sessions list](/platform/user-guide/vdi-experience/using-sessions-overview/sessions.md#sessions-list) and [sessions map](/platform/user-guide/vdi-experience/using-sessions-overview/sessions.md#sessions-map) on the [Sessions tab](/platform/user-guide/vdi-experience/using-sessions-overview/sessions.md).

The system preserves active filters across all tabs.

## Specifying timeframe

### Using timeframe picker

Use the timeframe picker in the top-right corner to select the time interval you want to investigate. The default timeframe is 4 hours.

### Zooming in on specific period

Drag the cursor over an area on the timeline to zoom in on a specific period.

The dashboard automatically applies the timeframe selection to the [#metrics](#metrics "mention") graph.

{% hint style="info" %}
The system preserves the selected timeframe across all tabs.
{% endhint %}

### Time resolution

You can select a timeframe of up to 30 days. Aside from the regular 5-minute data resolution, VDI Experience offers unique high-resolution data with 30-second time buckets for the last 2 days.

```mermaid
timeline
section Selectable timeframe — last 30 days
Day 30—2: 5-minute data resolution
Day 2—1: 30-second data resolution
```

The selected timeframe also affects the resolution of the bar chart and line chart, as shown in the following table.

| Interval   | Resolution |
| ---------- | ---------- |
| 1 hour     | 30-second  |
| 1—8 hours  | 5-minute   |
| 8—48 hours | 15-minute  |
| 4 days     | 30-minute  |
| 7 days     | 1-hour     |
| 15 days    | 2-hour     |
| 21 days    | 3-hour     |
| 30 days    | 4-hour     |

#### Example

The following figure shows a resolution of 5 minutes in a selected 6-hour interval anywhere in the past 30 days:

However, selecting a 1-hour interval in the past 2 days shows a fine-grain resolution of 30 seconds:
