I am following documentation and thanks to | line_format
and regexReplaceAll
I was able to fetch some substring from a line.
Let's say now I have those columns:
line
123
7
123
54
14
Having that I want to perform some transform operation, ex sum, or transform operation with grouping by and taking total. It is not working as I am suspecting those values are not being numbers, but only strings. Is it possible to convert it to numbers?
I was trying using unwrap
but it didn't worked:
sum_over_time(
{service="some"}
|="text expression"
| json
| line_format `{{ regexReplaceAll "text expression to remove from (\\d+)" .label_id "${1}" | trim }}`
| unwrap label_id [1m]
)
it ends up with
pipeline error: 'SampleExtractionErr' for series:
when I am filtering out errors, there is no results.
