I have a use case where I want to sample 25% of all successful trace
( which does not have error)。
I have 2 more use cases:
- Sample all error traces ( no problem)
- Sample all High latency traces (no problem)
I am using ADOT collector. Upon reading the README.md for tail sampling processor.
My understanding is that my use case can be achieved by using and
policy.Like combination go two policies
- Sample only Error free successful traces
- Sample only 25% probabilistic traces
I tried the following policy but not luck
{
name: send-percent-of-successful-traces,
type: and,
and:
{
and_sub_policy:
[
{
name: only-200-response-code,
type: string_attribute,
string_attribute:
{
key: http.response.status,
values: ["200"],
enabled_regex_matching: true,
},
},
{
name: sample-percent-traces,
type: probabilistic,
probabilistic: { sampling_percentage: 25 },
},
],
},
},
Is there any other way to achieve my use case?
Note: I already have 2 more policies to sample only error traces and high latency traces so I cannot use another processor to filter 404 error traces.
