Synthetic Monitoring FAQs

You can find the IP addresses on the Synthetic Monitor reference page.

Monitoring from infrastructure that is separate from where your application is hosted gives an unbiased perspective of your application health and performance, resulting in a more realistic picture of application availability and end-to-end performance for end-users.

Currently newly created monitors take ~2-3 min before data is available.

Health Policies are user-defined thresholds used to determine monitor health. Dynamic Thresholds are used to detect time-series anomalies using statistical algorithms, turning monitor health critical when the defined standard deviation values are exceeded for the specified evaluation period. Static Thresholds are fixed response times, turning monitor health critical when the defined thresholds are exceeded for the specified evaluation period.

To avoid false positives and reduce alert noisiness, Dynamic Threshold Health Policies require a week's worth of monitor data in order to establish what normal behavior is for the monitored endpoint. Monitors with Dynamic Threshold Health Policies enabled will look at the previous 7 day period on a rolling basis to calculate the new threshold daily.

To reduce sensitivity of your Dynamic Threshold Health Policy and alert less often, you can increase the standard deviation value and/or increase the evaluation period for the health policy. Increasing the standard deviation value will increase the dynamically calculated threshold that needs to be exceeded before the monitor goes critical. Increasing the evaluation period will increase the amount of time that the monitor latency needs to be in violation state before the monitor turns critical. To increase sensitivity and alert more often, you can reduce the standard deviation value and/or decrease the evaluation period.

The TLS monitor report always sources from US-EAST-1 within the reference page. This is the case regardless of the regions your performance and health monitors are set to.

The TLS report for a given HTTPs monitor is generated one time every 24 hours.

The overall TLS score comes from the SSL Lab's Server Rating Guide. You can view a detailed explanation of the specification here.

Monitor Executions represents the number of individual times a monitor has been run across all configured regions. The 3 factors that determine the monthly consumption for a monitor are:

• Number of Regions for the monitor
• Interval of the Monitor in minutes

Formula: (1440 (Minutes in a day) / <interval>) * (<Number of regions>) = Executions per day

Monitor Executions per interval per day:

Examples for a single monitor using a 1 min interval:

• 1440 (executions per day) x 1 Region x ~30 days in a month = 43,200
• 1440 (executions per day) x 3 Regions x ~30 days in a month = 129,600

Examples for a single monitor using a 5min interval:

• 288 (executions per day) x 1 Region x ~30 days in a month = 8,640
• 288 (executions per day) x 3 Regions x ~30 days in a month = 25,920

The base Organization plan includes 500,000 Synthetic Monitoring executions per month. For usage over the included 500,000 executions per month, please reach out to your account team for more information.
