List metric tag values for a metric - Automate.ax

axiom.listMetricTagValuesForMetric lists values observed for one tag on one metric. Use the result to build a valid exact filter without mixing values observed only on other metrics.

import { automation, onHttpRequest } from "automate.ax"
import { axiom } from "automate.ax/axiom"

export default automation("List metric tag values for a metric", () => {
  onHttpRequest({ scope: "automation" })
  axiom.listMetricTagValuesForMetric({
    datasetName: "metrics",
    metric: "http.server.duration",
    tag: "service.name",

Inputs

Input	Required	Default	Description
`datasetName`	Yes	—	OpenTelemetry metrics dataset name or ID.
`metric`	Yes	—	Non-empty metric name.
`tag`	Yes	—	Non-empty tag name.
`startTime`	No	30 minutes before execution	Discovery-window start as an RFC3339 timestamp.
`endTime`	No	Execution time	Discovery-window end as an RFC3339 timestamp.
`edgeUrl`	No	`"https://us-east-1.aws.edge.axiom.co"`	Axiom query edge or an HTTPS `*.edge.axiom.co` origin.

Set edgeUrl to the edge that stores the dataset.

Output

Returns values observed for the tag on the metric in the selected window as string[]. No observed values returns [].

Permission and failures

The API token needs the dataset-level query|read capability for datasetName. Axiom returns an error when the dataset, metric, or tag is missing or inaccessible, and rejects invalid time windows. Request-rate limits return 429, while exhausted query-cost limits return 430. Automate.ax uses Axiom’s reset timing when available.
