This project was developed during the second semester of the 2nd year of the Software Engineering degree @ University of Minho.
The project consisted of developing a system monitor, similar to the htop
command, using the C programming language and specially only system calls.
The project architecture is based on a server-client model, where the server is responsible for collecting the information and the client for running a program and displaying the result.
Examples of commands that can be used by a client:
execute -u "ls"
, which executes the commandls
and displays the result;execute -p "ls -la | grep x | wc -l"
, which executes a pipeline of commands and displays the result;status
, which displays all the current programs being executed by all the connected clients;stats-time <PID-x> <PID-y>
, which displays the CPU time used by the programs with the PIDs x and y;stats-uniq <PID-x> <PID-y>
, which displays the number of unique commands executed by the programs with the PIDs x and y;stats-command <PID-x> <PID-y> <command>
, which displays the number of times the command was executed by the programs with the PIDs x and y;
$ git clone [email protected]:ruilopesm/System-Monitor-SO.git
$ cd System-Monitor-SO
$ make
Note: You can also use make client
or make server
to compile only the client or the server, respectively.
$ ./bin/monitor
$ ./bin/tracer execute -u "ls"
