BloombergLP::balm::ConfigurationUtil::setFormatSpec

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".
