# Details
The queries in GenerateHostStatusStatistics (which feeds the
host_summary API) were incorrectly filtering out hosts that had been
removed from ABM from the denominator (i.e. "total hosts") count, while
keeping them in the per-platform counts. This PR fixes the query so that
the sum of the platforms matches the total.
