@Dam Mad Change the aggregator operator from
NOOP
to
SUM_RATE
. The graph will show you the result and based on that you can configure what is the ideal threshold.
Please scroll down it should be there

No,
SUM
would be incorrect operator. The
signoz_calls_total
is monotonic counter and we are interested in sum of rate because of that. If it is showing zero then either there was no 4xx request within the interval or data is in correct. Are you looking for a specific service? Can you filter by it and see what’s the chart? Is it a server kind or client kind span?

ok - found what was incorrect - threshold was set to 0.1, while the sum_rate values are very low and only 10x errors they are above 0.1
that's fine - I can set it that way - very low threshold value
I think it could be more intuitive if we could sat threshold 0, but SigNoz gives me error when I try to do so

setting
0
as the threshold should be allowed and not treated as empty. Can you raise an issue for this?
