Struct pprof::protos::Sample

[+] Show declaration

pub struct Sample {
    pub location_id: Vec<u64>,
    pub value: Vec<i64>,
    pub label: Vec<Label>,
}

[−] Expand description

Each Sample records values encountered in some program context. The program context is typically a stack trace, perhaps augmented with auxiliary information like the thread-id, some indicator of a higher level request being handled etc.

Fields

location_id: Vec<u64>

[−] Expand description

The ids recorded here correspond to a Profile.location.id. The leaf is at location_id[0].

value: Vec<i64>

[−] Expand description

The type and unit of each value is defined by the corresponding entry in Profile.sample_type. All samples must have the same number of values, the same as the length of Profile.sample_type. When aggregating multiple samples into a single sample, the result has a list of values that is the elemntwise sum of the lists of the originals.

label: Vec<Label>

[−] Expand description

label includes additional context for this sample. It can include things like a thread id, allocation size, etc
