Hi,
In OpenMetrics protobuf each metric (i.e. each time series) has an optional
timestamp:
message MetricPoint {
oneof value {
UnknownValue unknown_value = 1;
GaugeValue gauge_value = 2;
CounterValue counter_value = 3;
HistogramValue histogram_value = 4;
StateSetValue state_set_value = 5;
InfoValue info_value = 6;
SummaryValue summary_value = 7;
}
google.protobuf.Timestamp timestamp = 8;
}
However, this is NOT the created timestamp. Counters, Histograms, and
Summaries have a created timestamp in addition to that:
message CounterValue {
oneof total {
double double_value = 1;
uint64 int_value = 2;
}
google.protobuf.Timestamp created = 3;
Exemplar exemplar = 4;
}
I'm struggling to understand why there are two timestamps. Can we remove
one of them?
Fabian
