説明
The link to make changes to a the document here: https://grafana.com/docs/loki/latest/logql/log_queries/ is broken and leads to a 404 page in github. I would like to make a suggestion to edit this page based on feedback I have seen from the field.
In this section: https://grafana.com/docs/loki/latest/logql/log_queries/#pattern
By default, a pattern expression is anchored at the start of the log line. If the expression starts with literals, then the log line must also start with the same set of literals. Use <_> at the beginning of the expression if you don’t want to anchor the expression at the start.
add this to the end of that paragraph.
This means that you do not need to capture every part of the line in your pattern. You can create a pattern that only captures the part(s) of the line that you need.
An example that show this would also be good.
