Synthetic vs. RUM Approach

Synthetic Alerts and Real User Alerts should be used as part of your robust alerting strategy. Synthetic provides technical-rich alerts, while Real User provides alerts impacting actual customers’ journey.

Synthetic Tips

• Ensure to include targeted page names. This will provide a granular understanding of what is alerting.

• Lower synthetic volume will increase the frequency of outliers, increasing the synthetic test volume. The sample of the alert will help to address this without under-tuning the alert.

Real User Tips:

• Operational Variance on Real User is higher than Synthetic This is due to diversity of device, network conditions,

• the region, etc.

• Specified Value is often easier to manage than Percent Changed

• Include business metrics as a directional understanding of how technical factors alert the business.

• Include positive business alerts as well.
