SysUsage is a system monitoring and alarm reporting tool. The project can generate historical graph views of CPU, memory, IO, network and disk usage, and much more.


Once you have correctly installed and configured SysUsage the best way to run it is by croni job. As it is very fast you can set running time each minute. This is the default interval used in the graph report tool sysusagegraph. So I recommand you to do so or to modify this script to match you interval.

Here is how I use it with an installation with all path by default :

*/1 * * * * /INSTALL_DIR/sysusage
*/5 * * * * /INSTALL_DIR/sysusagegraph

If you have change the default installation path (/usr/local/sysusage) you need to give these script the path to the configuration into the command line argument using -c option. To know what arguments can be passed use option -h or --help.

Main features:

  • Load average.
  • CPUs usage. (total, system, user, iowait, idle, steal)
  • Memory usage (with and without cache).
  • Share memory usage (POSIX /dev/shm).
  • Swap usage.
  • Page swapping.
  • Page I/O stats.
  • R/W request stats.
  • R/W block stats.
  • Created process per second.
  • Percentage of open file regarding to file-max.
  • Number of socket in use. With TCP versus UDP.
  • Any active network interface usage.
  • Errors on network interface (bad packet, dropping, collision.
  • Any mounted partition disk space usage.
  • Monitoring running process.
  • Monitoring number of file in queue directory.
