Note: This article details the Catchpoint advanced test setting "Test Size Override Enabled" If you are looking for our documentation on system limits and thresholds, click here.
Test Download Limit
By default, Catchpoint tests have a maximum allowable size per test run or step. This limit is the total allowable bytes that can be downloaded in a single test run, such as a web browser test. Any test run that exceeds this limit will automatically fail with an error of 50013: “The test page reached the maximum file size limit".
You can see the default size limit in Settings > Info.
The download limit varies by node network type. Wireless (mobile) nodes have a limit of 5 MB per test run. Enterprise agents have no limit.
If needed, you can override this limit, allowing individual tests to exceed it. Test runs that exceed the default limit will be charged additional points as specified in the Point Charges section below.
Overriding the Default Size Limit
To enable a test to exceed the default limit, go to the Advanced Settings section of the test configuration and select the option "Test Size Override Enabled":
When this option is set, test runs or steps will be allowed to exceed the default limit up to an absolute maximum of 30 MB for backbone, cloud and last-mile nodes, or 15 MB for wireless. This limit is applied separately to downloads and uploads. E.G. a backbone node would be able to download up to 30MB and upload up to 30MB in a single test run or step. Above these maximums, all tests will be forced to fail with an error of 50013.
Remember, this is a per-test setting. Only tests with this option checked will be allowed to exceed the default limit.
Exceptions
- This feature does **not **apply to Enterprise Nodes. Enterprise agents ignore file size limits.
- This feature does not change the per-URL limit of 15 MB. This is fixed and cannot be overridden. A test with an individual URL greater than 15 MB will automatically fail with an error of 50012, even if the total test download size is less than the configured limit.
- The maximum download sizes are fixed and unchangeable: 30 MB for backbone, cloud and last-mile nodes, and 15 MB for wireless nodes.
Point Charges
Test runs below the default size limit incur no extra point cost, even if the override setting is checked.
Test runs that do exceed the default limit will be charged extra points. The additional charge is 1 point for every 5 MBs over the default limit, multiplied by the network factor. To clarify:
- A test run that exceeds the default limit by up to 5 MB will be charged +1 point * network factor.
- A test run that exceeds the default limit by 5 MB to 10MB will be charged +2 points * network factor.
- A test run that exceeds the default limit by 10 MB to 15MB will be charged +3 point * network factor.
... and so on, until the test run hits the maximum limit of 30 MB for backbone/cloud/last mile nodes, or 15 MB for wireless nodes.
Examples
Additional point charges are shown in the examples below. Each case assumes the default limit is 15 MB, and the test is set to allow it to exceed that limit, unless otherwise noted.
Example 1: Test size = 6 MB
Test run on Backbone nodes
- Network factor = 1
- Additional charge: None (test run size is below default limit)
Test run on Last-Mile nodes
- Network factor = 2
- Additional charge: None (test run size is below default limit)
Test run on Wireless nodes (default limit is automatically 5 MB)
- Network factor = 5
- Additional charge: 1 × 5 = +5 points per run or step per node
Example 2: Test size = 13 MB
Test run on Backbone nodes
- Network factor = 1
- Additional charge: None (test run size is below default limit)
Test run on Last-Mile nodes
- Network factor = 2
- Additional charge: None (test run size is below default limit)
Test run on Wireless nodes (default limit is automatically 5 MB)
- Network factor = 5
- Additional charge: 2 × 5 = +10 points per run or step per node
Example 3: Test size = 18 MB
Test run on Backbone nodes
- Network factor = 1
- Additional charge: 1 × 1 = +1 points per run or step per node
Test run on Last-Mile nodes
- Network factor = 2
- Additional charge: 1 × 2 = +2 points per run or step per node
Test run on Wireless nodes (default limit is automatically 5 MB)
- Network factor = 5
- Additional charge: No additional point charge. The test fails above the wireless max of 15 MB
Example 4: Test size = 26 MB
Test run on Backbone nodes
- Network factor = 1
- Additional charge: 3 × 1 = +3 points per run or step per node
Test run on Last-Mile nodes
- Network factor = 2
- Additional charge: 3 × 2 = +6 points per run or step per node
Test run on Wireless nodes (default limit is automatically 5 MB)
- Network factor = 5
Additional charge: No additional point charge. Test fails above the wireless max of 15 MB
