EBS Read IOPS reported incorrectly

[cyberchip-wang]

There is a couple of places where the metric 'Ops' should be used.
E.g., the template file batch-grafana-dashboard-template.json has the following section, where the EBSReadOps_Average should be used.

  "title": "EBS Read IOPS",
  "transformations": [
    {
      "id": "calculateField",
      "options": {
        "alias": "EBS Read IOPS",
        "binary": {
          "left": "EBSReadBytes_Average",
          "operator": "/",
          "reducer": "sum",
          "right": "60"
        },
        "mode": "binary",
        "reduce": {
          "include": [
            "EBSReadBytes_Average"
          ],
          "reducer": "sum"
        },
        "replaceFields": true
      }
    }
  ],
  "type": "timeseries"
}
