Monitor VM performance tiering with QoSSIOC events

Contributors netapp-pcarriga netapp-dbagwell amgrissino

You can view events related to QoSSIOC when a VM with a QoS-enabled datastore is reconfigured or issued a power or guest event.

You can view QoSSIOC events from the plug-in extension point in NetApp Element Plug-in for vCenter Server.

QoSSIOC events are displayed from locally added clusters. In a Linked Mode environment, log into the vSphere Web Client that has the cluster added locally to view QoSSIOC events for that cluster.

  • Beginning with Element vCenter plug-in 5.0, to use vCenter Linked Mode, you register the Element Plug-in from a separate management node for each vCenter Server that manages NetApp SolidFire storage clusters.

  • Using NetApp Element Plug-in for vCenter Server 4.10 and earlier to manage cluster resources from other vCenter Servers using vCenter Linked Mode is limited to local storage clusters only.

What you'll need
  • At least one cluster must be added and running.

  • The QoSSIOC service must be configured and verified running using the QoSSIOC Settings page for the plug-in.

  • At least one datastore must have QoSSIOC automation enabled.

  1. In your vSphere Web Client, open the QoSSIOC Events tab:

    • Beginning with Element vCenter plug-in 5.0, select NetApp Element Remote Plugin > Configuration > QoSSIOC Events.

    • For Element vCenter plug-in 4.10 and earlier, select NetApp Element Configuration > QoSSIOC Events.

QoSSIOC event data

  • Date: The date and time of the QoSSIOC event.

  • Datastore Name: The user-defined datastore name.

  • Cluster IP: The IP address of the cluster containing the datastore from which the event originated.

  • Volume ID: The system-generated ID for the associated volume.

  • Min IOPs: The current minimum IOPS QoS setting of the volume.

  • Max IOPs: The current maximum IOPS QoS setting of the volume.

  • Burst IOPs: The current maximum burst QoS setting of the volume.

  • Burst Time: The length of time a burst is allowed.
