“Santa Is Watching” (aka Santa_IW) is a new open-source network monitoring tool with an emphasis on ZFS and network attached storage in a homelab environment. Santa_IW can automatically discover hardware on your intranet and build up a list of appropriate tests which will then run periodically to monitor your network. Santa_IW uses keyed ssh to communicate with monitored nodes, and needs no additional agent installed.
