Monitoring the Nutanix Acropolis Server

eG Enterprise provides a specialized model for monitoring Nutanix Acropolis servers with VMs that host server applications.

Each layer of this model is mapped to tests that report on the resource usage of the hypervisor and the VMs inside-out, and point you to resource-hungry VMs and applications. Using the metrics reported by this model, administrators can find quick and accurate answers to the following performance queries:

  • Is the Acropolis server available over the network? If so, how responsive is the server to requests?
  • Is the content cache sized enough to handle requests, or are cache hits very low?
  • How much memory did deduplication save in the content cache?
  • Are any physical disks marked for removal? Has data from that disk been migrated?
  • Which physical disk is currently offline?
  • Is any physical disk being over-utilized?
  • Are there any latent physical disks?
  • How is the I/O performance of the physical disks?
  • Is I/O load balanced across all physical disks?
  • Is any physical disk consuming bandwidth excessively when processing I/O?
  • How is the I/O load on the storage?
  • Is the storage processing I/O requests quickly?
  • Is too much bandwidth being consumed when processing I/O?
  • Is the AHV sized with adequate storage resources? If not, what type of storage is running short of space - the SSDs? or the SATA HDDs?
  • How many VMs are operating on the Acropolis server? What is their IP address and which OS are they running?
  • Which VMs are currently powered off or suspended?
  • Which VMs have been newly added and which ones were recently removed from the server?
  • Which VM is the CVM of a cluster?
  • Is any VM consuming the physical CPU, memory, network, and I/O resources of the Acropolis server, abnormally?
  • Which VM is utilizing the CPU, memory, network, and I/O resources allocated to it, excessively? Which process on the VM is causing this abnormal resource consumption?
