Detailed Description

The Get-BrokerHypervisorAlert cmdlet gets alert objects reported by the hypervisors that the controller is monitoring.

Without parameters, Get-BrokerHypervisorAlert gets all of the alerts recorded. Use parameters to select which alerts are returned.

Once you have configured suitable alerts in your hypervisor, and configured the controller with your hypervisor details (see New-BrokerHypervisorConnection), the controller monitors each hypervisor for new alerts.

Four hypervisor alert metrics are recorded; these relate to the hypervisor host, not individual virtual machines:

  • Cpu: Reports excessive CPU usage.

  • Memory: Reports excessive memory usage.

  • Network: Reports high network activity.

  • Disk: Reports high disk activity.

Each alert also includes information about where and when the alert occurred, the severity of the alert (Red/Yellow), and the configuration of the triggered alert.

The following metrics are supported with these hypervisors:

  • VMware ESX (Cpu, Memory, Network, Disk)

  • Citrix XenServer (Cpu, Network)

  • Microsoft Hyper-V (None)

Brokerhypervisoralert Object

The BrokerHypervisorAlert represents a hypervisor alert object. It contains the following properties:

  • HostingServerName (System.String) The name of the hypervisor hosting this machine.

  • HypervisorConnectionUid (System.Int32) The Uid of the hypervisor connection that reported this alert.

  • MetadataMap (System.Collections.Generic.Dictionary<string, string>) Metadata for this hypervisor alert.

  • Metric (Citrix.Broker.Admin.SDK.AlertMetric) The metric this alert relates to: Cpu, Memory, Network, Disk, HostConnection or HostReboot.

  • Severity (Citrix.Broker.Admin.SDK.AlertSeverity) Severity of the alert (Red or Yellow). Red is more serious than Yellow.

  • Time (System.DateTime) Time that the alert occurred.

  • TriggerInterval (System.TimeSpan?) Number of ticks (100ns) before the alert can be raised again.

  • TriggerLevel (System.Double?) Threshold level that the alert was configured to trigger at.

  • TriggerPeriod (System.TimeSpan?) Duration the value was above the trigger level.

  • TriggerValue (System.Double?) The value of the monitored metric that triggered the alert.

  • Uid (System.Int64) The unique internal identifier of this alert.


Name Description Required? Pipeline Input Default Value
Uid Gets the hypervisor alert with the specified UID. true false  
HostingServerName Gets alerts for the specified hosting hypervisor server. false false  
HypervisorConnectionUid Gets alerts for the specified hypervisor connection. false false  
Metadata Gets records with matching metadata entries.      
The value being compared with is a concatenation of the key name, a colon, and the value. For example: -Metadata “abc:x*” matches records with a metadata entry having a key name of “abc” and a value starting with the letter “x”. false false    
Metric Gets alerts for a specified metric.      
Valid values are: Cpu, Memory, Network and Disk. false false    
Severity Gets alerts with the specified severity.      
Valid values are: Red and Yellow. false false    
Time Gets alerts that occurred at a specific time.      
You can also use -Filter and relative comparisons; see the examples for more information. false false    
TriggerInterval Gets alerts with a specific trigger interval. This is the interval before the alert is raised again. false false  
TriggerLevel Gets alerts with a specific trigger threshold level. false false  
TriggerPeriod Gets alerts with a specific trigger period. This is the duration the threshold level was exceeded for, prior to the alert triggering. false false  
TriggerValue Gets the value of the monitored metric that triggered the alert. false false  
ReturnTotalRecordCount When specified, this causes the cmdlet to output an error record containing the number of records available. This error record is additional information and does not affect the objects written to the output pipeline. See about_Broker_Filtering for details. false false False
MaxRecordCount Specifies the maximum number of records to return. false false 250
Skip Skips the specified number of records before returning results. Also reduces the count returned by -ReturnTotalRecordCount. false false 0
SortBy Sorts the results by the specified list of properties. The list is a set of property names separated by commas, semi-colons, or spaces. Optionally, prefix each name with a + or - to indicate ascending or descending order. Ascending order is assumed if no prefix is present. false false The default sort order is by name or unique identifier.
Filter Gets records that match a PowerShell style filter expression. See about_Broker_Filtering for details. false false  
FilterScope Gets only results allowed by the specified scope id. false false  
Property Specifies the properties to be returned. This is similar to piping the output of the command through Select-Object, but the properties are filtered more efficiently at the server. false false  
AdminAddress Specifies the address of a XenDesktop controller that the PowerShell snapin will connect to. This can be provided as a host name or an IP address. false false Localhost. Once a value is provided by any cmdlet, this value will become the default.
BearerToken Specifies the bearer token assigned to the calling user false false  
TraceParent Specifies the trace parent assigned for internal diagnostic tracing use false false  
TraceState Specifies the trace state assigned for internal diagnostic tracing use false false  
VirtualSiteId Specifies the virtual site the PowerShell snap-in will connect to. false false  

Input Type


You cannot pipe objects to this cmdlet.

Return Values


Get-BrokerHypervisorAlert returns an object for each matching alert.


Example 1

C:\PS> Get-BrokerHypervisorAlert -HostingServerName TestHyp\* -Severity Red



Returns all serious (Red) alerts for any hosting server with a name that starts with ‘TestHyp’.

Example 2

C:\PS> Get-BrokerHypervisorAlert -Filter { Metric -eq 'Cpu' -and Time -ge '-1:0' }



Returns all CPU usage alerts that occurred in the last hour.
