Christian Haudum	a56a88bd35	Add unwrapped aggregation `rate_counter()` (#6412) ... `rate_counter()` takes an unwrapped range as input, but unlike `rate()` it treats the values extracted from the log lines as "counter metric" like in Prometheus' `rate()` function. This is a replacement for the reverted change of #5013 Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	4 years ago
Christian Haudum	b315ed0ddf	Sum values in unwrapped rate aggregation instead of treating them as counter (#6361) ... * Revert unwrapped rate aggregation to previous implementation This PR reverts the implementation done in #5013 to the original implementation that sums the extracted values from the log lines instead of treating them like a Prometheus counter metric.

Karen Miller	24accf6a5b	Docs: correctly represent product name (#4416) ... The product name is Grafana Loki. The first use of the product name on each web page should be the full product name. After that, within each page, it is fine to use just Loki. This PR also set up some frontmatter with weights where it was missing on a few files, and correct where "Loki" was not capitalized.	4 years ago
