Code for the Concurrent and Realtime Programming UNIPD Course's oral exam.

Producer-(multiple) consumers program with remote status monitoring. An actor (thread or process), separate from the producer and the consumers shall periodically monitor the message queue length, the number of produced messages and the number of received messages for every consumer. The collected information shall be sent via TCP/IP to a server that shall print the received information.

To compile the source code, use the following command:

make all

If you want the extra debug information use

make debug

NOTE: Suggested number of consumers is 3 so that the queue fill level varies meaningfully.

First, you have to run the monitor server.

./monitor_server <monitor port>

Then, you have to run the client with producers, consumers and the monitor thread.

./main <n. consumers> <monitor ip> <monitor port> <monitor interval [s]>

Check which functions get inlined by the compiler.
