FAQ
How test evaluation and deduction works in Professional plan?
In Professional plan, test cost evaluation is based on VUM, where VUM = VU (virtual user, i.e. connections) * M (execution minutes). If there are available coupons that can be used for tests, the cost will be deducted from these coupons first. The remaining cost will then be deducted from test packs.
If the test is running via public network, the traffic cost from XMeter Cloud is also evaluated and charged.
What are the limitations for each MQTT test mode in Professional plan?
In Professional plan, test duration and connections have the following limitation:
| Test duration limit | Connections limit |
|---|---|
| <= 1,440 minutes (e.g. 24 hours) | <= 500,000 |
Also, there are specific limitations for different modes. You will receive detailed instruction messages if your settings exceed the limitations.
Specific limitations for each mode are listed as follows.
Connection-only: all connections must be established within given duration. In addition,
Total connections range <= 10,000 > 10,000 New connections per second limit <= 1,000, and not exceed total connections not exceed 1/10 of the total connections Publish:
Total connections range <= 1,000 > 1,000 Messages published per second limit <= 1,000, and not exceed 10 times of the total connections <= 500,000 and not exceed 10 times of the total connections Payload limit <= 102,400 bytes One-to-one:
Total connections range <= 1,000 > 1,000 Messages published per second limit <= 1,000, and not exceed 10 times of the total connections <= 250,000 and not exceed 10 times of the total connections Payload limit <= 102,400 bytes Fan-out:

What are the limitations for each MQTT test mode in Standard plan?
In Standard plan, test duration and connections have the following limitation:
| Test duration limit | Connections limit |
|---|---|
| <= 60 minutes (e.g. 1 hour) | <= 1,000 |
Also, there are specific limitations for different modes. You will receive detailed instruction messages if your settings exceed the limitations.
Specific limitations for each mode are listed as follows.
Connection-only: all connections must be established within given duration. In addition,
New connections per second limit <= 1,000 Publish:
Messages published per second limit <= 1,000 Payload limit <= 1,024 bytes One-to-one:
Messages published per second limit <= 500 Payload limit <= 1,024 bytes Fan-out:
Pub clients limit 1 Messages published per second limit 1 Payload limit <= 1,024 bytes Fan-in:
Sub clients limit <=10, and not exceed total connections Messages published per second limit <= 500 Payload limit <= 1,024 bytes
How long are trace logs and error logs kept?
XMeter Cloud cleans test logs regularly. Trace logs will be kept for 1 month, while error logs will be kept for 3 months. Logs other than trace logs and error logs will also be kept for 3 months. Please download and back up your important logs in time.
