Signoz builder and promQL shows different responses

[marshallslee]

Hello

I'm using SigNoz version 0.45.0 and was comparing the Builder mode with PromQL.

First, I ran a query using Builder mode, as shown below:

Then, I ran the following PromQL query:

sum by(os_type) (rate(process_disk_io{os_type="linux"}[4m]))

The two results were somewhat different. So I checked the JSON response and noticed that the PromQL result not only had different values but also contained more timestamp-value pairs.

So my questions are:

1. Did I make a mistake when trying to query the same data using both Builder and PromQL?

2. Is it not possible to get equivalent results using SigNoz Builder and PromQL? If so, why?
