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 limitConnections 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.

  1. 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 connectionsnot exceed 1/10 of the total connections
  2. 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
  3. 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
  4. Fan-out:

    Total connections range<= 1,000> 1,000
    Pub clients limit<= 1,000, and not exceed 1/10 of the total connections
    Messages published per second limit<= 1,000, and not exceed 100 times of the total connections<= 500,000 / total connections, and not exceed 100 times of the total connections
    Payload limit<= 102,400 bytes
  5. Fan-in:

    Total connections range<= 1,000> 1,000
    Sub clients limit<= 1,000, and < total connections
    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

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 limitConnections 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.

  1. Connection-only: all connections must be established within given duration. In addition,

    New connections per second limit<= 1,000
  2. Publish:

    Messages published per second limit<= 1,000
    Payload limit<= 1,024 bytes
  3. One-to-one:

    Messages published per second limit<= 500
    Payload limit<= 1,024 bytes
  4. Fan-out:

    Pub clients limit1
    Messages published per second limit1
    Payload limit<= 1,024 bytes
  5. 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.
