FieldStat

Number of errors whose path is this field. Note that we assume that error tracking does not require field-level instrumentation so this will include errors from requests that don't contribute to the observed_execution_count field (and does not need to be scaled by field_execution_weight).

Same as count but potentially scaled upwards if the server was only performing field-level instrumentation on a sampling of operations. For example, if the server randomly instruments 1% of requests for this operation, this number will be 100 times greater than observed_execution_count. (When aggregating a Trace into FieldStats, this number goes up by the trace's field_execution_weight for each observed field execution, while observed_execution_count above goes up by 1.)

Duration histogram for the latency of this field. Note that it is scaled in the same way as estimated_execution_count so its "total count" might be greater than observed_execution_count and may not exactly equal estimated_execution_count due to rounding.

Number of times that the resolver for this field is directly observed being executed.

Number of times the resolver for this field is executed that resulted in at least one error. "Request" is a misnomer here as this corresponds to resolver calls, not overall operations. Like errors_count above, this includes all requests rather than just requests with field-level instrumentation.
