Getting Index was outside the bounds of the array error when trying to scrape the metrics for virtual_machine and kubernetes

[HusnainTaja]

Hi,

Using promitor I am trying to scrape metrics from a virtual machine but getting this message in the logs:-

[20:14:00 FTL] Failed to scrape resource collection virtual-machine-landscape: Index was outside the bounds of the array.
System.IndexOutOfRangeException: Index was outside the bounds of the array.
   at System.Collections.Generic.Dictionary`2.TryInsert(TKey key, TValue value, InsertionBehavior behavior)
   at Promitor.Agents.Scraper.Scheduling.ResourceDiscoveryGroupScrapingJob.ExecuteAsync(CancellationToken cancellationToken)

And also getting error for kubernetes metrics:-

[20:14:00 FTL] Failed to scrape resource collection kubernetes-service-landscape: Index was outside the bounds of the array.
System.IndexOutOfRangeException: Index was outside the bounds of the array.
   at System.Collections.Generic.Dictionary`2.TryInsert(TKey key, TValue value, InsertionBehavior behavior)
   at Promitor.Agents.Scraper.Scheduling.ResourceDiscoveryGroupScrapingJob.ExecuteAsync(CancellationToken cancellationToken)

This are the metrics_declaration file:-

• name: node_cpu_usage_millicores
  description: "{Aggregated measurement of CPU utilization in millicores across the cluster}"
  resourceType: KubernetesService
  azureMetricConfiguration:
  metricName: node_cpu_usage_millicores
  aggregation:
  type: Average
  resourceDiscoveryGroups:

  • name: kubernetes-service-landscape

• name: available_memory_bytes
  description: "{Amount of physical memory, in bytes, immediately available for allocation to a process or for system use in the Virtual Machine}"
  resourceType: VirtualMachine
  azureMetricConfiguration:
  metricName: Available Memory Bytes
  aggregation:
  type: Average
  resourceDiscoveryGroups:

  • name: virtual-machine-landscape

  Request you to please help me as I am new to promitor
