The Event Trends report is one of the default reports that appears on the Ops Center Analyzer dashboard. It provides a trend report of all critical and warning alerts in your environment for the past 72 hours. It is useful in comparing the change history and the number of critical alerts, especially for an administrator who manages the entire system.
- When you hover over a specific bar in the trend report, a tool tip displays the total number of alerts, the number of critical alerts, and the number of warning alerts for a specific time period. Each bar represents an hour.
- Blue blocks at the bottom of the trend report indicate configuration changes for a specific time period. The darker the shade of blue, the larger the configuration change from one time period to the next.
- When you hover over a change history at the bottom of the trend report, the tool tip displays the number of changes in a specific time period. The date is in the format yyyy-mm-dd, and the time hh:mm.
If you see a spike on the trend report, navigate to the E2E View from the System Status Summary report to view the data center topology and review the configuration and status information. You can then use the Sparkline View and analytics workflow to solve the problem.
