Supported by `/api/v2` data queries and `json2` format. * `minify` - Remove unnecessary spaces and newlines from the output. * `debug` - Provide additional information in `jsonwrap` output to help tracing issues. * `nonzero` - Do not return dimensions that all their values are zero, to improve the visual appearance of charts. They will still be returned if all the dimensions are entirely zero. * `null2zero` - Replace `null` values with `0`. * `absolute` or `abs` - Traditionally Netdata returns select dimensions negative to improve visual appearance. This option turns this feature off. * `display-absolute` - Only used by badges, to do color calculation using the signed value, but render the value without a sign. * `flip` or `reversed` - Order the timestamps array in reverse order (newest to oldest). * `min2max` - When flattening multi-dimensional data into a single metric format, use `max - min` instead of `sum`. This is EOL - use `/api/v2` to control aggregation across dimensions. * `percentage` - Convert all values into a percentage vs the row total. When enabled, Netdata will query all dimensions, even the ones that have not been selected or are hidden, to find the row total, in order to calculate the percentage of each dimension selected. * `seconds` - Output timestamps in seconds instead of dates. * `milliseconds` or `ms` - Output timestamps in milliseconds instead of dates. * `unaligned` - by default queries are aligned to the the view, so that as time passes past data returned do not change. When a data query will not be used for visualization, `unaligned` can be given to avoid aligning the query time-frame for visual precision. * `match-ids`, `match-names`. By default filters match both IDs and names when they are available. Setting either of the two options will disable the other. * `anomaly-bit` - query the anomaly information instead of metric values. This is EOL, use `/api/v2` and `json2` format which always returns this information and many more. * `jw-anomaly-rates` - return anomaly rates as a separate result set in the same `json` format response. This is EOL, use `/api/v2` and `json2` format which always returns information and many more. * `details` - `/api/v2/data` returns in `jsonwrap` the full tree of dimensions that have been matched by the query. * `group-by-labels` - `/api/v2/data` returns in `jsonwrap` flattened labels per output dimension. These are used to identify the instances that have been aggregated into each dimension, making it possible to provide a map, like Netdata does for Kubernetes. * `natural-points` - return timestamps as found in the database. The result is again fixed-step, but the query engine attempts to align them with the timestamps found in the database. * `virtual-points` - return timestamps independent of the database alignment. This is needed aggregating data across multiple Netdata agents, to ensure that their outputs do not need to be interpolated to be merged. * `selected-tier` - use data exclusively from the selected tier given with the `tier` parameter. This option is set automatically when the `tier` parameter is set. * `all-dimensions` - In `/api/v1` `jsonwrap` include metadata for all candidate metrics examined. In `/api/v2` this is standard behavior and no option is needed. * `label-quotes` - In `csv` output format, enclose each header label in quotes. * `objectrows` - Each row of value should be an object, not an array (only for `json` format). * `google_json` - Comply with google JSON/JSONP specs (only for `json` format). required: false allowEmptyValue: false schema: type: array items: type: string enum: - jsonwrap - raw - minify - debug - nonzero - null2zero - abs - absolute - display-absolute - flip - reversed - min2max - percentage - seconds - ms - milliseconds - unaligned - match-ids - match-names - anomaly-bit - jw-anomaly-rates - details - group-by-labels - natural-points - virtual-points - selected-tier - all-dimensions - label-quotes - objectrows - google_json default: - seconds - jsonwrap dataTimeGroup1: name: group in: query description: | Time aggregation function.
