  and those that are unreachable.
@item Notifications when problems occur and get resolved (via email,
  pager, or user-defined method).
@item Ability to define event handlers for proactive problem resolution.
@item Automatic log file rotation/archiving.

     "HostScope displays key system metrics of Linux hosts, such as detailed
CPU load, speed and temperature, I/O rates of network interfaces, I/O rates of
disks, and user process summary information.  All metrics are multicast on the
LAN, if wanted, and clients can switch between multiple hosts on the network.
Hostscope features a bridge to Influx DB.  So Grafana can be used to visualize
the recorded data over time.")
