Task Overview Dashboard

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, the number of successful monitoring actions refers to the monitoring actions that meet the assertion conditions.
Overall time	The interval between the start of Alibaba Cloud DNS (DNS) resolution and the completion of download.
Download speed	The average download speed during the specified time range. `Average download speed = Number of downloaded bytes/Download duration`
Number of tests	The number of synthetic tests in this task.
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 assertion conditions.
City Dial Test Overview	The following metrics are displayed by city: Availability: the availability in the region. Overall time: the interval between the start of DNS resolution and the completion of download. DNS Time: the time spent on Alibaba Cloud DNS resolution to translate domain names to IP addresses. Connection time: the time spent on establishing TCP connections during the test file download. SSL Usage: the time spent on SSL handshake. Request sending time: the time spent on sending requests during the test file download. Waiting for response: the time it takes for the client to receive the first packet from the server after sending the request. download time: the time spent on downloading the test file. Download speed: the average download speed of the test file. Number of tests: the total number of synthetic tests that are initiated from the region.
Availability Trends	The availability trend during the specified time range.
Time trend of each stage	Overall time: the interval between the start of DNS resolution and the completion of download. DNS Time: the time spent on Alibaba Cloud DNS resolution to translate domain names to IP addresses. Connection time: the time spent on establishing TCP connections during the test file download. SSL Usage: the time spent on SSL handshake. Request sending time: the time spent on sending requests during the test file download. Waiting for response: the time it takes for the client to receive the first packet from the server after sending the request. download time: the time spent on downloading the test file. Download speed: the average download speed of the test file.
Average download time (city)	The trend of the average download time by city.
Average download time (carrier)	The trend of the average download time by ISP.
Download Speed (city)	The download speed trend of synthetic tests by city.
Download speed (operator)	The download speed trend of synthetic tests by ISP.
The city's slowest Top5	Top five cities with the slowest average download speed.
Slowest operators Top5	Top five ISPs with the slowest average download speed.
Error Type Top5	Top five types of errors.

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.
