Installing

Requirements

• Java 8
• Maven 3.X.X

Tested environment:

Apache Maven 3.8.1 (05c21c65bdfed0f71a2f2ada8b84da59348c4c5d)
Maven home: C:\Users\Georges\Development\Tools\apache-maven-3.8.1\bin\..
Java version: 1.8.0_291, vendor: Oracle Corporation, runtime: C:\Program Files\Java\jdk1.8.0_291\jre
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

Steps

1. Install the dev branch of NanoSatMO Framework (NMF) following the NMF quick start guide

2. Get and build

$ git clone https://github.com/georgeslabreche/opssat-datapool-param-dispatcher
$ mvn install

3. Deploy the application in the NMF SDK following the NMF deployment guide. Replacing instances of "sobel" by "datapool-param-dispatcher" and "Sobel" by "DatapoolParameterDispatcherApp" in the main class name.

Starting

Configuring

The app is configured via the config.properties file. Number of aggregations to build and the row write frequency in which the fetched values are written to the output CSV files:

aggregations=4
flush.write.at=10

Each aggregation is configured to fetch n parameters of a certain type for i iterations and whether or not the output is appended to an existing CSV file or if a new file is created on each run. For instance, to fetch 15 Float parameters for 5 iterations at intervals of 2 seconds:

iterations.1=5
interval.1=2000
params.get.count.1=15
params.get.type.1=Float
params.get.output.csv.1=toGround/thread_01.csv
params.get.output.csv.append.1=false

Parameters can also be explicitly listed:

iterations.2=10
interval.2=1000
params.get.names.2=GNC_0005,GNC_0011,GNC_0007
params.get.output.csv.2=toGround/thread_02.csv
params.get.output.csv.append.2=true

Running

Follow the last 3 steps of the NMF SDK guide.

Alternatively, use the build.bat script after editing the PROJECT_DIR and NMF_SDK_PACKAGE_DIR to match your development environment's file system. Running build.bat builds the project. Running build.bat 1 builds and runs the project.
