Click **+ New Alert** or **Add on Alert +** Observability sidebar with New Alert button On Create new alert page, you can specify the following details * Alert name : Name of the alert * Alert priority : Preference on how alert will be categorized * Run frequency : How often the metric is run and check to be within the threshold * Alert Notification : List of emails to be notified Create new alert form with name, priority, frequency, and notification fields Add an **Alert trigger**. You may select an existing metric or create a new metric. Here we are going to create a new metric. Specify which **Data store** you wish to connect. Then select a **Table** and **Column** to be used in the metric. Here, we selected **Null** as **Metric type** to detect nulls. See Available Metric Types page to see list of metrics. Alert trigger setup selecting data store, table, column, and Null metric type You can add **conditions** specific to columns available in the table. For this example, only rows with column id of 1 will be checked for nulls. Adding a column condition to filter which rows are checked **Threshold** is the level a metric needs to cross to generate an alert. Specify either of the two thresholds values (Alert if below, Alert if above) or both. Threshold configuration with Alert if below and Alert if above fields ## Related
