Set the format specification for the metric aggregate indicated by the specified `category`, `metricName`, and `publicationType` to the specified `formatSpec`. Optionally specify a metrics `manager` to configure. If `manager` is 0, configure the default metrics manager; if `manager` is 0 and the default metrics manager has not been initialized, this method has no effect. Return 0 on success, or a non‐zero value if `manager` is 0 and the default metrics manager has not been initialized. If a `MetricId` does not exist for `category` and `metricName`, create one and add it to the metric registry of the indicated metrics manager. For example a publication type of `e_AVG`, and a format spec with a scale of 1000.0 and a format of "%.2f ms", indicates that the average value of the indicated metric should be formatted by scaling the value by 1000 and then rounding the value to the second decimal place and appending " ms".
