Solution

Page Composition is the total number of objects, hosts, connections, and bytes. If any individual metric's one-hour average is less than the threshold set for the 24 hour average, the yellow icon is displayed.

For example, the Page Composition Thresholds is 25%. If the current hour's average for total objects downloaded,  total hosts connected, total number of connections, or total bytes downloaded is less than 25% of the 24-hour average, the yellow icon is displayed.

Note that the recent average is compared to the historical data, including failed tests. Thus you the test may be "green" even though test is failing.

For response time, the calculation to determine the alert status depends on the unit you select for the threshold.

  • If you selected seconds, the one hour average response time is compared to the thresholds you set.
  • If you selected percentage, the one hour average response time is compared to a 24 hour average.

For availability, the one-hour average is compared to the thresholds you set.
