Bad Request: Not supported about qryn

[akvlad]

Hello. Do you request something like topK(5, rate({a="b"} | json [10m])) ?

[gauravpareekk]

I don't think so. This is the error we're seeing from Grafana dashboard end.

[akvlad]

Well Not supported\nBad Request: Not supported in this case means that topK with | json or | logfmt is not supported.
Please try using | json a="obj.a" - json with parameters with topK.
I'll recheck the grafana agent but it seems like a human built request with | json and topk from grafana explore or a dashboard.

[gauravpareekk]

ok do we have a rebuilt dashboard that can be used?

[gauravpareekk]

I'm using the prebuilt dashboard and just imported that to grafana

[akvlad]

can you please share a link to the prebuilt dashboard you use? is it from an open source?

[akvlad]

another question. "reqId":"req-2k"
can you please filter the logs by req-2k string and paste the request causing the error?

[akvlad]

do you have a widget named Top Exceptions inside the prebuilt dashboard?

[gauravpareekk]

Yes

[akvlad]

I think I see the source of the prebuilt dashboard you have.
https://github.com/grafana/faro-web-sdk/blob/main/dashboards/frontend-application.json#L995
As you see at this line https://github.com/grafana/faro-web-sdk/blob/main/dashboards/frontend-application.json#L990C11-L990C23

topk(10, count(count_over_time({kind="exception", app="$app"} | logfmt [$__range])) by (value))

The request is not supported for now. We should either replace it or support it.
I'll think about that. Maybe it's easier to make a quick replacement.

[gauravpareekk]

sure, thanks. At this moment, we can't do anything about it?

[akvlad]

We will suggest the requests replacements shortly.

[akvlad]

Suggested replacements for some of widgets of the dashboard:

Top Exceptions
topk(10, count(count_over_time({kind="exception", app="$app"} | regexp "value=(?<value>([^\"]+|\"[^\"]+\"))" [$__range])) by (value))

Top URLs by Exception Count
topk(10, count(count_over_time({kind="exception", app="$app"} | regexp "page_url=(?<page_url>([^\"]+|\"[^\"]+\"))" [$__range])) by (page_url))

Top Browsers by Exception Count
topk(10, count(count_over_time({kind="exception", app="$app"} | regexp "browser_name=(?<browser_name>([^\"]+|\"[^\"]+\")).*browser_version=(?<browser_version>([^\"]+|\"[^\"]+\"))" [$__range])) by (browser_name, browser_version))

Popular Browsers
topk(10, count(count_over_time({app="$app",kind="measurement"} |= " ttfb=" | regexp "browser_name=(?<browser_name>([^\"]+|\"[^\"]+\")).*browser_version=(?<browser_version>([^\"]+|\"[^\"]+\"))" [$__range])) by (browser_name, browser_version))

Top Events
topk(10, count(count_over_time({kind="event", app="$app"} | regexp "event_name=(?<event_name>([^\"]+|\"[^\"]+\"))" [$__range])) by (event_name))

The Not supported error should not appear after the changes are made.

It's an interesting logic to replace logfmt to regexp if possible. Sounds like a feature request. Thanks for the issue.

[gauravpareekk]

thank you for helping here. We were able to pull the data. However, these ones are still throwing error

Cumulative Layout Shift, p75
quantile_over_time(0.75, {kind="measurement",app="$app"} |= " cls=" | logfmt | unwrap cls [5m]) by (app)

First Input Delay, p75
quantile_over_time(0.75, {kind="measurement",app="$app"} |= " fid=" | logfmt | unwrap fid [5m]) by (app)

Page Load, p75
quantile_over_time(0.75, {kind="measurement",app="$app"} |= " ttfb=" | logfmt | unwrap ttfb [5m]) by (app)

quantile_over_time(0.75, {kind="measurement",app="$app"} |= " fcp=" | logfmt | unwrap fcp [5m]) by (app)

quantile_over_time(0.75, {kind="measurement",app="$app"} |= " lcp=" | logfmt | unwrap lcp [5m]) by (app)

[akvlad]

I see. Will provide the same replacement.
Feel free to do it yourself. Just replace | logfmt with | regexp "lcp=(?<lcp>([^\"]+|\"[^\"]+\"))"

[gauravpareekk]

thank you that worked
