Hi, is it possible to show only traces in the traces view, by default Signoz shows both traces and their spans which makes it a bit hard for me to find the information that I need (screenshot for a reference). Also, is it possible to exclude certain routes, as I have healthcheck route which is triggered every few seconds and unnecessarily bloats the view. Thanks!

This is upcoming in a month. We are launching a new explorer page with that option
is it possible to exclude certain routes, as I have healthcheck route which is triggered every few seconds and unnecessarily bloats the view
should be possible. @Srikanth Chekuri can you help?

What data that you need to view for traces and not spans? Would be helpful to understand. @Aleksandar Babic

ideally I would be able to toggle to show/hide the spans in the list shown on
/trace
, so when needed I can see only the traces without the spans, and then when I want to see spans of the specific trace I click on it to open the detailed view (trace details page)

by this do you mean root span? since trace is really a bunch of spans.

@Srikanth Chekuri yes, thats what I’ve meant
@Srikanth Chekuri the URL exclude list seems to be working, the only issue is that my healthcheck is on the
/
route, and I’m not sure which value should I set to exclude only that URL and not any other. With value
OTEL_PYTHON_EXCLUDED_URLS=/
It excludes all root spans for all urls

@Aleksandar Babic Try
^/$
It should only match
/
route

tried it, it excluded all of the routes except the healthcheck one, so basically opposite of what I was heading towards to @Vishal Sharma

Strange,
^/$
is regex to match only
/
Can you set
OTEL_PYTHON_FASTAPI_EXCLUDED_URLS="^/$"
I tested this regex: https://regex101.com/r/lrtXtU/1

I’ll test the
OTEL_PYTHON_FASTAPI_EXCLUDED_URLS
in a few minutes. One thing that crossed my mind from https://opentelemetry-python-contrib.readthedocs.io/en/latest/instrumentation/fastapi/fastapi.html#exclude-lists - it seems like they are not including the trailing slashes in the values, for example they wrote that in order to exclude
/healthcheck
route you need to set value
OTEL_PYTHON_FASTAPI_EXCLUDED_URLS=healtcheck
which does not include the
/
, could that be the problem?
OTEL_PYTHON_FASTAPI_EXCLUDED_URLS
behaving exactly the same

Yes, it doesn’t include the trailing slash. I recommend you to some straightforward endpoint like
/healthz
or
/healthcheck
and exclude it instead of the root URL.

that is probably the best approach. Thanks for the help @Srikanth Chekuri @Vishal Sharma
@Srikanth Chekuri @Vishal Sharma I was able to actually solve it with the following value for excluded URLs:
^(https?://)?[^/]+(/)?$
The regex
^/$
would have worked if the url that was passed to the validation function was only relative (
/
), but instead its the full URL (
<http://server>:port/
) and requires the above regex in order to properly filter out the
/
URL. Thanks for the guidance, much appreciated! I love Signoz and will start using it in prod very soon!
