System Monitor

• Reads the following statistics information from the linux file system:

  • CPU: /proc/stat
  • Disk: /sys/block/sda/stat
  • Net: /proc/net/dev/
  • Memory: /proc/meminfo

• Captured data entries are configurable through the print_flag variable in sysmon.c (See include/print_flags.h for flag definitions).

• Monitoring interval can be configured with the INTERVAL_SEC macro in sysmon.c.

• Some files/functions are adapted from:

  • sysstat (https://github.com/sysstat/sysstat)
  • top (http://sourceforge.net/projects/unixtop/)

• Usage

 $ make
 $ ./sysmon 1 log.txt // real-time logging enabled & save monitored data in "log.txt"
