Clustered Data ONTAP: SMB Latency Monitor (microseconds)

DataONTAP.Cluster.DataVserver.SMBServer.SMBLatencyMonitor (UnitMonitor)

The SMB Latency (microseconds) Monitor monitors the value of the Storage Virtual Machine I/O counter collected by the SMB Performance Statistics Collection Rule.

Knowledge Base article:

Summary

The SMB Latency (microseconds) Monitor monitors the value of the Storage Virtual Machine I/O counter collected by the SMB Performance Statistics Collection Rule:

Counter Name: Storage Virtual Machine I/O

Instance Name: SMB Latency (microseconds)

Configuration

Two overrides are available for this monitor. Threshold and number of samples trigger an alert when the value of the performance counter is greater than the threshold for the specified number of consecutive samples. The alert is autoresolved when the underlying condition is resolved.

The default threshold is 50000 microseconds.

The default number of samples is 4.

Resolutions

Inspect the contents of the alert to determine its cause.
