The alerts histogram shows the number of alerts and their severity over time, which can help you identify patterns in the alerts.
Move the cursor across the histogram, or hover over points in the graph to see the number of alerts and their severity for that time stamp. You can quickly and easily filter the histogram or table to show only the alerts that are most relevant to your investigation:
Select an option from one or more of the drop down menus Time Range, Assignee, Status, or Generated By.
Click on a data point in the histogram to show only alerts for that time stamp in the table.
Click a severity to add or remove all alerts with that severity from the histogram and table.
