expected equal, got "INVALID"

[Maksim Podbereznov]

Hey.

I got an error, maybe filter it or fix it

curl --header 'Host: "exemple.com' 10.10.10.8

curl -s http://**********:9927/metrics | promtool check metrics 2 error while linting: text format parsing error in line 177: unexpected end of label value ""

is it possible to implement a filter?

I suspect the error is on one of the previous lines, possibly 176, which you didn't show.

Here's an approach you can try:

1. write the metrics to a file

2. divide the file into two parts

3. run promtool check metrics on the two parts. Presumably one half is OK and one gives an error.

4. take the half which gives an error

5. go back to step 2

Eventually you'll find the bad line.
