Querying Metrics

Instant Query

const metrics = yield* AMP.QueryMetrics(workspace);

const result = yield* metrics.query({ query: "up" });
if (result.resultType === "vector") {
  for (const sample of result.result) {
    console.log(sample.metric.__name__, sample.value[1]);
  }
}

Range Query

const result = yield* metrics.queryRange({
  query: "rate(http_requests_total[5m])",
  start: new Date(Date.now() - 3_600_000),
  end: new Date(),
  step: "30 seconds",
});
