The **Reliability** section provides visibility into endpoint stability across your organization by
analyzing system and application event logs. It helps administrators identify instability trends,
investigate recurring issues, and maintain consistent endpoint performance.

## Reliability events

Two types of reliability events are monitored:

- **Application Events** – Related to Windows system components such as drivers and built-in system elements
- **System Events** – Related to installed programs and third-party software

Each event is categorized by severity:

- **Critical**
- **Error**
- **Warning**

This classification makes it easier to identify problematic endpoints and prioritize investigation.

## Reliability Score

The **Reliability Score** is a numerical indicator of endpoint stability, indexed from **1 to 10**.

As the number and severity of errors increase, the Reliability Score decreases. Maintaining a high
score helps ensure stable systems and consistent user productivity across your environment.

### Reliability Score chart

The **Reliability Score Chart** provides a historical view of stability over time.

The **blue line** represents the average Reliability Score, while the color distribution reflects the
stability range across endpoints.

When viewing all devices, the displayed score represents the **average reliability across the
organization**.

Hovering over a point in time displays:

- **Time Period** – The selected interval
- **Average Reliability Score** – Organizational average for that period
- **Reliability Score Range** – Lowest and highest score among endpoints
- **Device Count** – Number of devices included in the calculation

Clicking a time point drills down and filters results to that specific period.

### Reliability Score pie chart

The **Reliability Score Pie Chart** provides a visual distribution of endpoint stability levels.

Selecting a segment displays the list of devices within that stability range, enabling targeted
investigation and remediation.

## Event bar chart

The **Event Bar Chart** provides a time-based overview of event distribution by severity.

Each bar represents the number of:

- **Critical events**
- **Error events**
- **Warning events**

Hovering over a bar displays:

- **Time Period**
- **Critical Count**
- **Error Count**
- **Warning Count**
- **Affected Devices**

Clicking a bar drills down and filters results to the selected time period.

## Agent severity list

The **Agent Severity Lists** display the **top 10 devices** with the highest number of events within
each severity category.

Selecting a device redirects you to that endpoint's event logs for detailed analysis.

## Filters

Filtering options allow administrators to narrow results and focus on the most relevant reliability
data. Access filters using the **filter icon** in the upper-right corner.

Available filters include:

- **Description** – Full-text search within event descriptions
- **Log Type** – Filter by *Application* or *System* events
- **Source** – Filter by event source
- **Event ID** – Filter by specific event IDs

Events can also be filtered directly by selecting a device from the **Agent Severity List** or by
clicking a severity category.

## Time period and detailed view

![Time period and detailed view](/attachments/capaone/5c681fc2-5e5d-4677-95c8-6f7168e67d3c.png)

Use the **time selector** in the upper-right corner to define the reporting range:

- **Today**
- **Last Three Days**
- **Last Seven Days**
- **Last Month**

Reliability data can also be viewed in two modes:

- **Summary Mode** – Combines Application and System events into a unified view
- **Detailed Mode** – Separates Application and System events for deeper analysis
