On what basis are the spans colored? My java application is autoinstrumented and mades JDBC calls. However all the spans appear blue. I’d like for the spans with attribute db.system=mssql to be colored differently. How can I do this?

No, you can not specify color codes.
Errors are in red.
Palash can you please confirm?

vishal-signoz the sample app that Signoz ships has different colors for spans but here each span belongs to a separate service

I’d like my database msssql show up as separate service similar to the redis or myqsl service in the sample app

designing a color system might be a good idea. Sanjiv can you create an issue for this, might be helpful to others users also

Sanjiv DB are not shown as different services. The hot rod shows them in services because it sets service.name for databases. They are not really databases but a simply go programs mimicking the DB behaviour.

Is there a way to programatically update the service.name of a Span? Setting an attribute “service.name” on the Span does not result it the new service name being applied

Sanjiv service.name is not a span level attribute, rather it is a resource attribute.

do you know how I can set the resource attribute using Java API’s

Resource attributes can only be added when initializing the instrumentation in a service.
So you can’t change resource attribute for a individual span.

vishal-signoz ok, thanks

However, you can use multiple (tracer/meter/logger)providers within same service each with different resource attributes, then they will show up as different services in the UI.

vishal-signoz apart from the error we are assigning the colour in a round-robin fashion for different service
