This topic describes the metrics that are displayed on the dashboard of a ping 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. |
Average Latency | The time that elapses from the time when ICMP requests are sent to the time when responses are received. This metric is used to evaluate the response speed and stability of the network. |
Packet loss rate | Packet loss rate = Lost packets/Total transmitted packets × 100% |
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. |
Packet Loss Rate Trend | The trend for the packet loss rate in the specified time range. |
Response Time (City) | The trend for the average latency of HTTP or HTTPS requests by city. |
Response Time (Operator) | The trend for the average latency of HTTP or HTTPS requests by carrier. |
Tracert Delay | The average latency of all hops during the Tracert process. |
Tracert Hop | The number of network devices involved in the Tracert process. |
The city's slowest Top5 | Top five cities with the highest average latency. |
Slowest operators Top5 | Top five carriers with the highest average latency. |
Error Type Top5 | Top five types of errors that occur in responses. |
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.
