NUM MISSING SEGMENTS I think <https github com apache incubator pinot blob master pinot common src main java org apache pinot common metrics ServerMeter java L61>

It looks like this can happen in the window between when a segment is removed from the server and a broker sees the ExternalView change Maybe this is too challenging to manually trigger so I should tell ops not to worry about trying to validate
