- Comments starting with `#` and ending with newline. For instance, `up # this is a comment for 'up' metric`.
- Rollup functions - `rollup(m[d])`, `rollup_rate(m[d])`, `rollup_deriv(m[d])`, `rollup_increase(m[d])`, `rollup_delta(m[d])` - return `min`, `max` and `avg`
values for all the `m` data points over `d` duration.
- `candlestick(m[d])` - returns `open`, `close`, `low` and `high` values for all the `m` data points over `d` duration. This function is useful for financial applications.
- `rollup_candlestick(m[d])` - returns `open`, `close`, `low` and `high` values for all the `m` data points over `d` duration. This function is useful for financial applications.
- `union(q1, ... qN)` function for building multiple graphs for `q1`, ... `qN` subqueries with a single query. The `union` function name may be skipped -
the following queries are equivalent: `union(q1, q2)` and `(q1, q2)`.
- `ru(freeResources, maxResources)` function for returning resource utilization percentage in the range `0% - 100%`. For instance, `ru(node_memory_MemFree_bytes, node_memory_MemTotal_bytes)` returns memory utilization over [node_exporter](https://github.com/prometheus/node_exporter) metrics.
