# Widget Use Cases

> Step-by-step examples of using Count, Time Shifted Graph, and Table widgets to monitor log counts, errors, apps, and authentication attempts.

You can use widgets to monitor various aspects of application health. To learn how to build a Screen to monitor your web application, see [Use Screens and Widgets to Monitor Log Data](https://logdna.slite.com/app/docs/7uw4zKMJ-P3H80).

This article lists some other ways you can use Widgets.

## Count All Log Lines for the Past Day

1. Create a **Count** widget.
2. Set the duration to **Last 1 Day**.
3. Optionally set the host and field value if you want to filter the log lines.

## Monitor Error Logs

There are multiple ways to measure error logs.

### **Time Shifted Graph**

Compare errors over a period.

1. Create a **Time Shifted** widget.
2. Set field to `level`.
3. Select **Advanced** filtering and enter the query `level:(warn OR error)`.
4. Set the duration to **Last 1 Week**.

### **Count**

See the number of errors using a filter.

1. Create a **Count** widget.
2. Select **Advanced** filtering and enter the query `level:(warn OR error)`.
3. Set the **Duration** to **Last 1 Week.**
4. To get a view of errors over time, you can create the widget again and choose a different duration.

### **Table**

Use a table to see error levels.

1. Create a **Table** widget.

2. Under **Data**:

   1. Set **Group by** to `level`.
   2. Set **Field** to `All Lines`.

3. Set **Duration** to `Last 1 Week`.

4. Under **Appearance**:

   1. Set Left Column Label to `Level`.
   2. Set Right Column Label to `Counts`.

## See Log Lines by App

1. Create a **Table** widget.

2. Under **Data**:

   1. **Group** by `app`.
   2. Set **Field** to `host`.
   3. Optionally set the field value.

3. Set the **Duration**.

4. Under **Appearance**:

   1. Set Left Column Label to `App`.
   2. Set Right Column Label to `Counts`.

## Authentication Attempts

1. Create a **Count** widget.

2. Under **Data**:

   1. Set **Field** to `host`.
   2. Set **Field** value to the host you want to monitor.
   3. Click **Advanced Monitoring** and add `authentication`
