# Add a New Alarm (Tag Anomaly Detection Alarm)
## Introduction
You can create a new Tag Anomaly Detection Alarm to monitor unusual tag activity.
## Procedure
To add a new Tag Anomaly Detection Alarm, perform the following steps:
**Step 1:** Select **Alarms** from the left navigation panel.
**Step 2:** Click **Add Alarm** on the top-right corner of the screen.
**Step 3:** Select the **Tag Anomaly Detection Alarm**.
**Step 4:** In the **Name** field, enter the alarm name, and in the **Description** field, enter a brief description of the alarm.
**Step 5:** Under **Environment**, click the **Select Environment** dropdown. Two options are available — **Production** and **Staging**. Click the appropriate option.
**Step 6:** Enter the details mentioned in the **Settings** section.
**Threshold Sensitivity:**
* **High** sensitivity: The anomaly detection trigger will fire and send alert if it detects an anomaly at least ONCE in the previous hour.
* **Medium** sensitivity: The anomaly detection trigger will fire and send alert if it detects an anomaly once in the past 2 consecutive hours.
* **Low** sensitivity: The anomaly detection trigger will fire and send alert if it detects an anomaly once in the past 3 consecutive hours.
The Tag behavior is determined using the Bollinger Band.
**Preferred Timings:**
Select the exact tag monitoring period from the **Preferred Timings** drop-down. This is an optional setting. For example, If there is a sudden spike in traffic in the evenings, you could set the preferred timing from 5 p.m. to 10 p.m. The tag firing activities will be monitored every evening between 5 p.m. to 10 p.m.
**Note:** The tags are monitored continuously with a set preferred timing.
**Step 6:** Enter the details in the **Filter Conditions** section.
You can make the alarm more specific by creating monitors on specific tags, providers, or other attributes. To filter the alarms, perform the following steps:
* On the alarm page, click **Add Filter**.
