Stackdriver target

[nicolas-my-happn]

What does this do?

Add Stackdriver target

Why is it a good idea?

Stackdriver (GCP) isn't currently supported as target in Grafanalib

Context

Stackdriver target allows to generate dashboard for GCP, such as this:

  "targets": [
    {
      "aliasBy": null,
      "datasource": {
        "type": "stackdriver",
        "uid": "zzz"
      },
      "metricType": null,
      "queryType": "timeSeriesList",
      "refId": "A",
      "timeSeriesList": {
        "alignmentPeriod": "cloud-monitoring-auto",
        "crossSeriesReducer": "REDUCE_SUM",
        "filters": [
          "resource.label.project_id",
          "=",
          "my-project",
          "AND",
          "resource.label.job_name",
          "=",
          "dataflow-job",
          "AND",
          "metric.type",
          "=",
          "dataflow.googleapis.com/job/system_lag"
        ],
        "groupBys": [],
        "perSeriesAligner": "ALIGN_MAX",
        "preprocessor": "none",
        "projectName": "my-project",
        "view": "FULL"
      }
    }
  ]
