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.

Useful for json fields that can be missing, like HTTP headers in a log line that aren't required as in the following: ``` {job="access_log"} \| json \| line_format `{{.http_request_headers_x_forwarded_for \| default "-"}}` ``` Previously this could only be done (that I found) with the much more verbose ``` {{regexReplaceAllLiteral "^$" .http_request_headers_x_forwarded_for "-"}} ``` * update changelog entry * add pr number * enhance docs * Update docs/sources/logql/template_functions.md Co-authored-by: Kaviraj Kanagaraj <kavirajkanagaraj@gmail.com> * Update docs/sources/logql/template_functions.md Co-authored-by: Vladyslav Diachenko <82767850+vlad-diachenko@users.noreply.github.com> Co-authored-by: Kaviraj Kanagaraj <kavirajkanagaraj@gmail.com> Co-authored-by: Owen Diehl <ow.diehl@gmail.com> Co-authored-by: Vladyslav Diachenko <82767850+vlad-diachenko@users.noreply.github.com>	4 years ago

Cyril Tovena	4d1da2edf3	first_over_time and last_over_time (#3050 ) * Wip Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * [POC] last_over_time and first_over_time. This is an attempt to allow users to select the first or last discrete sample values from a range vector. This way we can create gauge, the only drawback being the log need to exists at least in every range. May be we could transfer the last or first value to the next range, but it will still be a problem for small ranges. Still wondering how useful this is compare to min/max_over_time.
