[bug] Pyroscope data-source not found after the plugin is installed

[hazra-mms]

Bug description

We have installed the plugin in our grafana infrastructure, we are having datasource for pyroscope already enabled but the plugin explore view doesn't find the datasource. Hence we can not use this.

Steps to reproduce

Install the plugin following https://grafana.com/grafana/plugins/grafana-pyroscope-app/?tab=installation ( we installed manually and through plugin section in the helm chart). Navigate to Profiles --> Explore Profiles

Actual behaviour

Error TypeError: Failed to fetch

Error in developer console in chrome

Expected behaviour

I expect the UI would load the profile correctly as the pyrooscope data source is configured already.

Do you mind sharing ...

• ... if the datasource config page like in the screenshot says "Type: Grafana Pyroscope"
• ... if the test of the datasource is successful
• ... the version of Grafana you are running

Thanks that should help us find the problem 🙂

[hazra-mms]

Thanks for your reply, please find the details. Our pyroscope setup is working and we can get the details from the explore view also. It's just issues with the plugin that we face.

We are running Grafana version 10.4.3 which is configured using the helm chart.

In case you need any further information please let me know.

Hi @hazra-mms,

Thank you for the info, may I also ask you to share:

• the URL of the browser after trying to access the "Explore Profiles" page
• the full URL of one of the failing requests, the one that ends up with /Series on your screenshot ?

Thanks, we're still trying to figure out where the problem could be.

Hi @grafakus ,

Sorry for the delay, please find the information below.

https:///grafana/a/grafana-pyroscope-app/profiles-explorer?searchText=&layout=grid&hideNoData=off&explorationType=all&var-serviceName=&var-profileMetricId=process_cpu:cpu:nanoseconds:cpu:nanoseconds&var-dataSource=pyroscope

url for failing request contains: http://localhost/grafana/api/datasources/proxy/uid/pyroscope/querier.v1.QuerierService/Series

Not sure why localhost is used here.

Thanks @hazra-mms. Would you mind sharing part of your settings.ini file in [server] section? The localhost is taken from root_url config which by default is:

root_url = %(protocol)s://%(domain)s:%(http_port)s/

By setting domain/protocol to:

[server]
http_port = 80
domain = grafana

or

[server]
http_port = 80
root_url = http://grafana/

I was able to load the plugin from https://grafana/...:

Also, do you have serve_from_sub_path set in your settings?
