The Health Checker for UNIX/Linux (HC) is a small framework of monitoring & validation scripts. It is meant to be used for low latency & low frequency checks, it is easy to extend where necessary (plugins) and it can be integrated with other toolsets (YMMV).

It requires:

  • ksh88/ksh93 (mksh/pdksh will work also but YMMV)
  • UNIX cron or other scheduler
  • some disk space for storing logs & event files
  • system dependant tools/utilities (see individual health checks)
  • execute as user root only


Download the software from following GitHub repository:

An Ansible role for deploying & configuring the toolset is also available at following GitHub repository:
