| Combined with parsers, metric queries can also be used to calculate metrics from a sample value within the log line, such as latency or request size. | ||
| All labels, including extracted ones, will be available for aggregations and generation of new series. | ||
| By using aggregation operators and functions, you can convert a set of log entries into a single numeric value or a time series. This helps you compute totals, rates, and trends based on either the number of log lines or a label. If you use a parser, you can calculate metrics using values from inside the log lines. You can use any label, including indexed or parsed labels, to create aggregations and generate new series. |
