2. Build from Source

# Clone the repository
git clone https://github.com/yourusername/system-monitor.git
cd system-monitor

# Generate gRPC code
protoc --grpc_out=. --cpp_out=. system_monitor.proto

# Build server
g++ -std=c++17 server.cpp system_monitor.grpc.pb.cc system_monitor.pb.cc \
    -lgrpc++ -lprotobuf -lprocps -lssl -lcrypto -o server

# Build client
g++ -std=c++17 client.cpp system_monitor.grpc.pb.cc system_monitor.pb.cc \
    -lgrpc++ -lprotobuf -lncurses -lpanel -lfmt -lssl -lcrypto -o client

3. Docker Installation

# Build and run using Docker
docker-compose up -d

Usage

1. Start the Server

./server

2. Start the Client
