Justin Burnham	97c7d7ca3c	LogQL: add the `default` sprig template function to logql label/line formatter (#6163) ... * add the `default` sprig template function to logql label/line formatter With the `default` sprig template function, we will be able to make it easier to output a default value if the source string is otherwise empty. 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

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

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
