Linux-Metrics-Collector

A metrics collection application for Linux machines. Created for MSCS 710 Project at Marist College.

Development Environment Setup

The technologies used to develop this application require development tools themselves to make changes to the project as a whole. This section discusses how to access and make changes to the various modules which make up the frontend and backend of the project.

First Steps

• Download Rust
• Download IntelliJ IDEA Community Edition
• Download Rust and TOML plugins for IntelliJ IDEA
  • In IntelliJ IDEA go to File > Settings > Plugins
  • Type "Rust" in the search bar and click Install
  • When asked to install TOML, click Yes
• Clone this repository and open it in IntelliJ
  • In the toolbar, click File > Open > ~/.../Metrics-Collector

Rust Server

• Setup run configuration for server
  • From the project root, open the 'server/src' directories
  • Select the main.rs file in the project hierarchy
  • In the toolbar, click Run > Edit > Configurations
  • Click "Add a new configuration" > cargo
  • Name the configuration "server"
  • Set the working directory to
    • ~/.../Metrics-Collector/server
  • Check the box that says "Run with root privileges"
• Click on the Cargo.toml file and click Attach in the top left of IntelliJ
• Hit Ok and try running the application

Interacting with the Database

• Running the server will automatically create a database if it is not there already.
  • It will appear in the 'metrics_collector_controllers' directory
• To query the database
  • Enter your terminal and cd into the metrics_collector_controllers directory
  • Enter the sqlite3 command
  • Enter .open data.db
  • Query with "SELECT * FROM process;"
• Editing or building upon the database
  • Whenever the database must be changed or restarted, the 'data.db' file has to be deleted from the project folder
  • Rebuild it by re-running the server
