Given my recent problems caused by Sage assuming 'top' existed, I decided to write some code which gives at least some of the information of top (see full usage below). It basically gives data by the system level, and by the process level.
drkir...@smudge:[~] $ ./a.out physical_ram_in_MB 8192 drkir...@smudge:[~] $ ./a.out processor_speed 1200 drkir...@smudge:[~] $ ./a.out physical_processors 2 Now find information about PID 1877 (data below is in MB) drkir...@smudge:[~] $ ./a.out image_size 1877 377.5 drkir...@smudge:[~] $ ./a.out resident_size 1877 188.2 Below is what is implemented so far. Can anyone think of anything else useful, that perhaps might be needed for gathering information for bug reports? I'll then implement what I can of these, using system calls. Note I've implement the load averages in two ways: * System as a whole * Processors available to Sage, which might have a very different load average if its running in a Solaris Zone or as a virtual machine with only a limited number of processors available. My intension is to add something to Sage so this sort of information can be found on Solaris. I'll leave it to others to get the data from linux, OS X etc. There is more of a need on Solaris, as 'top' which is currently called to get memory usage is not universally implemented. Also, as a trac item shows, using 'top' causes timeouts in one package as this is called thousands of times and takes a second each time.
