Camel Labs Performance Testing Framework
Camel IoT Labs comes with the Performance Testing Framework that can be used to define the hardware profiles and test scenarios. Performance framework takes care of detecting the devices connected to your local network, deploying the test application into these, executing the actual tests and generating the results as the human-readable chart. For example the sample output for the MQTT QOS testing could generate the following diagram:When to use Performance Testing Framework
Performance Testing Framework excels when you would like to answer the following question - how the different field hardware setups perform against the given task. And to answer that question just connect your devices to the local network, execute the performance testing application and compare the generated diagrams.Here is the 30 seconds video guide demonstrating how easy it is to perform the test:
Hardware profiles
This section covers the hardware profiles for the performance tests. Profiles are used to describe the particular hardware configuration that can be used as a target device for the performance benchmark. Every performance test definition can be executed on the particular hardware profiles.The example of the hardware profile can be Raspberry PI 2 B+ (aka RPI2). The RPI2 hardware profile is just the Raspberry Pi 2 B+ model equipped with the network connector (WiFi adapter or the ethernet cable). Currently we assume that the device is running Raspbian operating system (version 2015-05-05).
The other profile we defined for the Camel Labs is the Raspberry is the PI 2 B+ with BU353 (aka RPI2_BU353) The RPI2_BU353 hardware profile is the same as RPI2 profile, but additionally equipped with the BU353 GPS receiver plugged into the USB port.
Running the performance tester
The easiest way to run the performance benchmark is to connect the target device (for example Rapsberry Pi) into your local network (for example via the WiFi or the Ethernet cable) and start the tester as a Docker container, using the following command:docker run -v=/tmp/gateway-performance:/tmp/gateway-performance --net=host camellabs/performance-of RPI2
Keep in mind that RPI2 can be replaced with the other supported hardware profile (like RPI2_BU353). The performance tester detects the tests that can be executed for the given hardware profile, deploys the gateway software to the target device, executes the tests and collects the results. When the execution of the benchmark ends, the result diagrams will be located in the /tmp/gateway-performance directory (or any other directory you specified when executing the command above). The sample diagram may look as follows:
Keep in mind that currently we assume that your Raspberry Pi has default Raspbian SSH account available (username: pi / password: raspberry).
