### Describe Your Changes Add storage metrics that count records that failed to insert: - `RowsReceivedTotal`: the number of records that have been received by the storage from the clients - `RowsAddedTotal`: the number of records that have actually been persisted. This value must be equal to `RowsReceivedTotal` if all the records have been valid ones. But it will be smaller otherwise. The values of the metrics below should provide the insight of why some records hasn't been added - `NaNValueRows`: the number of records whose value was `NaN` - `StaleNaNValueRows`: the number of records whose value was `Stale NaN` - `InvalidRawMetricNames`: the number of records whose raw metric name has failed to unmarshal. The following metrics existed before this PR and are listed here for completeness: - `TooSmallTimestampRows`: the number of records whose timestamp is negative or is older than retention period - `TooBigTimestampRows`: the number of records whose timestamp is too far in the future. - `HourlySeriesLimitRowsDropped`: the number of records that have not been added because the hourly series limit has been exceeded. - `DailySeriesLimitRowsDropped`: the number of records that have not been added because the daily series limit has been exceeded. --- Signed-off-by: Artem Fetishev <wwctrsrx@gmail.com> |
