Christian Simon	2ff6f13c8b	Better error message for empty selector queries (#6936) ... This improves the error when an empty label selector is given: Before: ```sh-session # Before $ logcli query "{}" Error response from server: parse error at line 1, col 2: syntax error: unexpected }, expecting IDENTIFIER # After $ logcli query "{}" Error response from server: parse error : queries require at least one regexp or equality matcher that does not have an empty-compatible value. For instance, app=~".*" does not meet this requirement, but app=~".+" will ``` I fear that might have wider implications, so it would be great to get a lot of eyes on this. In theory I think we should remove the restriction on querying all log streams, but this should maybe discussed in a follow up PR 🙂 Co-authored-by: Karsten Jeschkies <karsten.jeschkies@grafana.com>	3 years ago

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.

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.

Cyril Tovena	c971e8e65a	Optimizes SampleExpr to remove unnecessary line_format. (#3065) ... * Optimizes SampleExpr to remove unnessary line_format. When doing count_over_time and rate(), it doesn't make sense to have a line_format since you're counting line, you don't really care about what the line contains. At the same time this set the foundation of for further optimization, like parsing only required labels during label parsing. I've also found a bug where `topk by(foo) (1...` where not correctly parsed. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * For all range vector operations.

Cyril Tovena	3f0800dc44	Add function label_replace. (#3047) ... You might be wondering why do we need label_replace when we already have label_format. Well for two reasons: 1. It's nice to have something similar to Prometheus, so users building metric queries will feel right at home. 2. Interestingly, they are quite different in how they execute. label_format executes for every log line, however label_replace execute for every sample. Since you aggregate log lines into sample then label_replace is way more efficient at scale. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com>	5 years ago
Cyril Tovena	2406ea72bc	Allows by/without to be empty and available for max/min_over_time (#3030) ... * Allows by/without to be empty and available for max/min_over_time operations. This essentially allows to aggregate over all dimensions when using by () while without() is a noop. This also makes it possible for max and min range vector aggregation to use grouping, which is simpler than doing max by (foo) max_over_time(...) Examples: - `max_over_time(...) by ()` gives your the max over time accross of all series. - `min_over_time(...) by (namespace)` gives you the min over time per namespace. - `max_over_time(...) without (namespace)` gives you the max over time removing the namespace dimension. PS: I've also refactored a bit how we optimized grouping to make it more clear. Fixes #2884 Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * nit doc.

Cyril Tovena	049c7acc12	Improve logql parser allocations. (#2927) ... * Improve logql parser allocations. Also moving labels parsing into logql package, and I'm not shy to say that promql is faster for this. So we're using promql for parser, it's faster because their lexer is more sophisticated than ours. Result are impressive. ``` ❯ benchcmp before.txt after.txt benchmark old ns/op new ns/op delta Benchmark_ParseLabels-16 24394 8745 -64.15% benchmark old allocs new allocs delta Benchmark_ParseLabels-16 156 20 -87.18% benchmark old bytes new bytes delta Benchmark_ParseLabels-16 24976 2099 -91.60% ``` Combined with #2926, I think we should be able to get rid of `util.ToClientLabels`.
