HTTP REST Api endpoint query last - IBM/ibm-spectrum-scale-bridge-for-grafana GitHub Wiki

• /api/query/last

  • Supported for OpenTSDB API
  • This endpoint provides support for accessing the latest value of individual time series. It provides an optimization over a regular query when only the last data point is required
  • You can send a metric name and optionally a set of tag pairs. Grafana-bridge will send the metric query for the last data point and return the result
