Monitor NFS Datastores
You can monitor NFS Datastore performance in vCenter and in Cloud Monitoring:
- vCenter: Provides performance metrics as observed by the ESXi hosts and cluster on which the NFS Datastore is mounted.
- Cloud Monitoring: Provides performance metrics for NFS volumes from Filestore and Google Cloud NetApp Volumes, as observed by the respective service. We recommend using Cloud Monitoring metrics to monitor the performance of your file shares, track latency, and set up alerts based on your workload's needs.
VMware Engine automatically monitors your NFS Datastores for potential issues. When a condition requires your attention or indicates a problem, VMware Engine generates an alert. You receive these alerts as emails sent to the essential contacts for your project and as entries in Cloud Logging.
The following sections describe the alerts you might receive.
High storage usage
Alert name: vmware_nfs_datastore_storage_usage_high
This alert triggers when the used space on an NFS Datastore exceeds 80% of its total capacity.
Recommended action: To resolve the issue, increase the size of the underlying NFS volume to avoid running out of space.
Example notification:
The private cloud `{.PCName}` in project `{.ProjectNumber}` can be affected because
the used space for the NFS Datastore `{.NFS_Datastore}` has exceeded
80%. Increase the size of your NFS volume and Datastore to avoid an out-of-space
condition and disruption to your applications. If you have any questions,
contact Cloud Customer Care.
Datastore inaccessibility
Alert name: vmware_host_datastore_nfs_mount_inaccessible
This alert triggers when one or more ESXi hosts in a cluster cannot access a mounted NFS Datastore.
Recommended action: This alert indicates an issue that the VMware Engine team is actively working to resolve. If you have questions, contact Cloud Customer Care.
Example notification:
The NFS Datastore `{.NFS_Datastore}` in private cloud `{.PCName}`
mounted to cluster `{.cluster}` is inaccessible from one or more hosts in
cluster `{.cluster}`. The VMware Engine team is aware of the issue and is working on a
resolution. If you have any questions, contact Cloud Customer Care.
Unmanaged Datastore detected
Alert name: vmware_nfs_datastore_not_allowed
This alert triggers when VMware Engine detects an NFS Datastore that you mounted manually, without using the VMware Engine API. These unmanaged Datastores aren't supported going forward.
Recommended action: To ensure proper integration and support, contact Cloud Customer Care to schedule a migration of the unmanaged Datastore to a fully managed VMware Engine Datastore.
Example notification:
Google Cloud VMware Engine Service identified an NFS volume within your Google Cloud project `{.ProjectNumber}` as a mounted NFS Datastore in your private cloud `{.PCName}` but is not managed by VMware Engine. To ensure seamless operation and proper integration, contact Cloud Customer Care to arrange its no-data-copy migration.
