@Bast i see. I think background workers are not currently displayed in service map. Though we should have better error messages for this. Can you open an issue for this?

Sure
So with only background worker it's not possible to see external bottleneck ?
it's too bad because I can see HTTP POST but impossible to filter by URL

@Bast Can you share more details on what d you mean by
filter by URL
? Do you want to filter by specific URL that HTTP post is made to?
there's a
HTTP URL
filter in the bottom of left filter panel. Have you checked that?

Yes and it's empty. One of my use case his to check external service performance with the data get from my trace Because when filtering by "Operation" with "HTTP POST" it's for all services.
For HTTP URL since it's background process I think it's not fill
