This topic describes the metrics that are displayed on the dashboard of a DNS task.
Procedure
Log on to the ARMS console.
In the left-side navigation pane, choose Synthetic Monitoring > Scheduled Tests. On the Synthetic Tasks page, click the name of the task.
Metrics
Metric | Description |
Availability | The success rate for the monitoring points of the synthetic monitoring task to access the destination. The availability is calculated based on the following formula: Availability = Number of successful monitoring actions/Total number of monitoring actions × 100%. In this formula, successful monitoring actions refer to the monitoring actions that meet the conditions specified in Availability Assertion. |
parsing time | The average time consumed for DNS resolution. |
Number of tests | The total number of synthetic tests during the specified time range. |
Number of errors | The number of failed synthetic tests during the specified time range. Failed synthetic tests are synthetic tests that do not meet the conditions specified in Availability Assertion. |
Region Dial Test Overview |
|
Availability Trends | The availability trend during the specified time range. |
DNS Resolution Time Trend | The trend for DNS resolution time during the specified time range. |
Resolution Time (City) | The trend for DNS resolution time by city. |
Resolution Time (Operator) | The trend for DNS resolution time by carrier. |
The city's slowest Top5 | Top five cities with the longest DNS resolution time. |
Slowest operators Top5 | Top five carriers with the longest DNS resolution time. |
Error Type Top5 | Top five types of errors that occur during DNS resolution. |
Task analysis
The task analysis feature allows you to combine filter conditions and aggregate dimensions for real-time analysis based on all data on which synthetic tests have been performed. This feature helps meet requirements for custom monitoring in different scenarios. For more information, see Task analysis.
