Alerts and notifications

Alerts are displayed in Director on the dashboard and other high-level views with warning and critical alert symbols. Alerts are available for Premium licensed sites. Alerts update automatically every minute; you can also update alerts on demand.

A warning alert (amber triangle) indicates that the warning threshold of a condition has been reached or exceeded.

A critical alert (red circle) shows that the critical threshold of a condition has been reached or exceeded.

You can view more detailed information on alerts by selecting an alert from the sidebar, clicking the Go to Alerts link at the bottom of the sidebar or by selecting Alerts from the top of the Director page.

In the Alerts view, you can filter and export alerts. For example, Failed Multi-session OS machines for a specific Delivery Group over the last month, or all alerts for a specific user. For more information, see Export reports.

Citrix alerts

Citrix alerts are alerts monitored in Director that originate from Citrix components. You can configure Citrix alerts within Director in Alerts > Citrix Alerts Policy. As part of the configuration, you can set notifications to be sent by email to individuals and groups when alerts exceed the thresholds you have set up. For more information on setting up Citrix Alerts, see Create alerts policies.

Note:

Ensure that your firewall, proxy, or Microsoft Exchange Server do not block the email alerts.

Smart alert policies

A set of built-in alert policies with predefined threshold values is available for Delivery Groups and Multi-session OS VDA scope. This feature requires Delivery Controller(s) version 7.18 or later. You can modify the threshold parameters of the built-in alert policies in Alerts > Citrix Alerts Policy. These policies are created when there is at least one alert target -a Delivery Group or a Multi-session OS VDA defined in your site. Additionally, these built-in alerts are automatically added to a new delivery group or a Multi-session OS VDA.

In case you upgrade Director and your site, the alert policies from your previous Director instance are carried over. Built-in alert policies are created only if no corresponding alert rules exist in the Monitor database.

For the threshold values of the built-in alert policies, see the Alerts policies conditions section.

Advanced alert policies

The Proactive Notification and Alerting feature of the Director is enhanced to include a new alerting framework named Advanced Alert Policies. With this feature, you can create alerts by including granular details for each element or condition, thereby enhancing the control over the alerts scope. Currently, these policies include alerts for cost savings and infrastructure.

With the introduction of Advanced alert policies, which is a data source-driven alert you can use multi-condition scope filtering.

This feature helps you to reduce excessive alerts which might lead to reduced responsiveness or effectiveness in addressing important issues. This policy helps to measure effectiveness of alert policies and engagement from admins.

You can create an Advanced alert policy from the Alerts > Advanced alert policy > Create Policy section.

You can select the category as Power Managed Machines failed to power on, Power Managed Machines failed to power off, Power Managed Machines with high uptime and then select the required conditions for the policy. For more information on how to create a policy, see Create alert policies. After the policy is created, you can edit, delete, or disable the policy on the Citrix Alerts page.

You can select the specific parameters and the corresponding options for each of the preceding conditions.

The Power Managed Machines with high uptime category checks the following metrics:

• Number of machines crossing uptime threshold
• Re-alert interval (in min) interval can be minimum 60 min

The Power Managed Machines failed to power on and the Power Managed Machines failed to power off categories checks the following metrics:

• Number of machines crossing uptime threshold
• Sampling interval (in min) intervals can be multiples of 30 min
• Re-alert interval (in min) re-alert can be multiples of 60 min

You can set the severity of the preceding categories as required. You can also schedule re-alert intervals for these alerts.

Define the scope of the policy

You can define the scope of your alert and add exceptions. The alert is generated only for the selected scope and the subscope excluded using add exceptions aren’t included in alert generation. This feature helps you to create alerts on a granular level.

You can create notifications through emails or through webhook URLs. You can also select your preferred language in which you would like to receive alerts. You can also select an option to receive the alert parameters in a .CSV file attachment for email or in a json payload through a webhook URL. The attachment includes details of the required parameters. For more information, see Enhancements on alert content.

The following data is received as an alert over email or on the Citrix Alerts page:

How to create an Advanced alert policy using a PowerShell script?

PowerShell script to create an alert policy:

asnp Citrix.Monitor.*
# Add Parameters
$timeSpan = New-TimeSpan -Seconds 30
$alertThreshold = 1
$alarmThreshold = 2
# Add Target UID's
$targetIds = @()
$targetIds += "e9a211b4-a1f3-4f74-b6c7-85225902e997"
# Add email addresses
$emailaddress = @()
$emailaddress += "loki@abc.com"
# Create new policy
$policy = New-MonitorNotificationPolicy -Name "FailedMachinePercentageAlertCreationViaPowershell" -Description "Policy created to test urm" -Enabled $true
<!--NeedCopy-->

Replace the following line with the correct condition for FailedMachinePercentage

Add-MonitorNotificationPolicyCondition -Uid $policy.Uid -ConditionType FailedMachinePercentage -AlertThreshold $alertThreshold -AlarmThreshold $alarmThreshold -AlertRenotification $timeSpan -AlarmRenotification $timeSpan

Add-MonitorNotificationPolicyTargets -Uid $policy.Uid -Scope "DG-Multisession" -TargetKind DesktopGroup -TargetIds $targetIds

$policy = Get-MonitorNotificationPolicy -Uid $policy.Uid
$policy

Infrastructure policies (Preview)

These policies are introduced to create alerts related to the health of supported Citrix Virtual Apps and Desktops components.

Once the Infrastructure monitoring setup is completed, you can use the health data available in Director to configure alerts for any required component. Admins can set conditions, scopes, and notification mediums to receive important alerts through emails or a json payload through webhooks. The alerts raised are also available in the Citrix Alerts section for analysis and management.

As a part of the newly introduced Infrastructure policy, alert conditions are categorized into four sections as follows:

• Reachability
• Dependent services
• Impact
• Resource utilization

Conditions within each category can be set with the severity of Critical and Warning based on your organizational priorities. You can also schedule re-alert intervals for these alerts.

You can create an infrastructure policy from the Alerts > Citrix Alert Policies section. You can select the required category and then select the required conditions for the policy. For more information on how to create a policy, see Create alert policies. After the policy is created, you can edit, delete, or disable the policy on the Citrix Alerts page.

For more details on the conditions supported in each category and component, see the following:

• PVS health metrics
• StoreFront health metrics

The following data is received as an alert over email or on the Citrix Alert page:

Create alert policies

To create an alert policy, for example, to generate an alert when a specific set of session count criteria is met:

1. Go to Alerts > Citrix Alerts Policy and select, for example, Multi-session OS Policy.
2. Click Create.
3. Name and describe the policy, then set the conditions that have to be met for the alert to be triggered. For example, specify Warning and Critical counts for Peak Connected Sessions, Peak Disconnected Sessions, and Peak Concurrent Total Sessions. Warning values must not be greater than Critical values. For more information, see Alerts policies conditions.
4. Set the Re-alert interval. If the conditions for the alert are still met, the alert is triggered again at this time interval and, if set up in the alert policy, an email notification is generated. A dismissed alert does not generate an email notification at the re-alert interval.
5. Set the Scope. For example, set for a specific Delivery Group.

6. In Notification preferences, specify who must be notified by email when the alert is triggered. You have to specify an email server on the Email Server Configuration tab to set email Notification preferences in Alerts Policies.

   1. You can also receive the alert content in a .CSV attachment or through the json payload. For this, select the following checkboxes:

      • Include a json payload as an attachment in the webhook
      • Include a csv file as an attachment in the email

   Note:

   To receive alert content through .CSV attachment and json payload options are available only for a few alerts currently. For more information, see Enhancements on alert content

7. Click Save.

Creating a policy with 20 or more Delivery Groups defined in the Scope might take approximately 30 seconds to complete the configuration. A spinner is displayed during this time.

Creating more than 50 policies for up to 20 unique Delivery Groups (1000 Delivery Group targets in total) might result in an increase in response time (over 5 seconds).

Moving a machine containing active sessions from one Delivery Group to another might trigger erroneous Delivery Group alerts that are defined using machine parameters.

Note:

After you delete an alert policy, it might take up to 30 minutes for the alert notifications generated by the policy to stop.

Enhancements on alert content

The alerting feature of the Director is enhanced to include a CSV attachment and a JSON payload. With this enhancement, you can get alert details in a CSV attachment over email or as a JSON payload if there is a webhook. Using this CSV attachment or JSON payload, you can receive enriched content at a detailed level, aiding in the quick identification and resolution of issues.

Currently, this enhancement is available only on the following alerts:

• Machine uptime
• Failed power on actions
• Failed power off actions
• Unregistered machines (%)

To use this feature, navigate to the alert and select the following checkboxes:

• Include a json payload as an attachment in the webhook
• Include a csv file as an attachment in the email

The following is a screenshot from the Citrix Alert Policies section:

Here is a screenshot from Advanced Alert Policies section:

CPU

Percentage of CPU usage indicates the overall CPU consumption on the VDA, including that of the processes. You can get more insight into the CPU utilization by individual processes from the Machine details page of the corresponding VDA.

• Go to Machine Details > View Historical Utilization > Top 10 Processes, identify the processes consuming the CPU. Ensure that the process monitoring policy is enabled to initiate collection of process level resource usage statistics.
• End the process if necessary.
• Ending the process causes unsaved data to be lost.

• If all is working as expected, add additional CPU resources in the future.

  Note:

  The policy setting, Enable resource monitoring is allowed by default for the monitoring of CPU and memory performance counters on machines with VDAs. If this policy setting is disabled, alerts with CPU and memory conditions are not triggered. For more information, see Monitoring policy settings

  Smart policy conditions:

  • Scope: Delivery Group, Multi-session OS scope
  • Threshold values: Warning - 80%, Critical - 90%

Memory

Percentage of Memory usage indicates the overall memory consumption on the VDA, including that of the processes. You can get more insight into the memory usage by individual processes from the Machine details page of the corresponding VDA.

• Go to Machine Details > View Historical Utilization > Top 10 Processes, identify the processes consuming memory. Ensure that process monitoring policy is enabled to initiate collection of process level resource usage statistics.
• End the process if necessary.
• Ending the process causes unsaved data to be lost.

• If all is working as expected, add additional memory in the future.

  Note:

  The policy setting, Enable resource monitoring, is allowed by default for the monitoring of CPU and memory performance counters on machines with VDAs. If this policy setting is disabled, alerts with CPU and memory conditions are not triggered. For more information, see Monitoring policy settings

  Smart policy conditions:

  • Scope: Delivery Group, Multi-session OS scope
  • Threshold values: Warning - 80%, Critical - 90%

Connection Failure Rate

Percentage of connection failures over the last hour.

• Calculated based on the total failures to total connections attempted.

• Determine if applications or desktops are reachable.

Connection Failure Count

Number of connection failures over the last hour.

• Check Director Connection Failures Trends view for events logged from the Configuration log.
• Determine if applications or desktops are reachable.

ICA RTT (Average)

Average ICA round-trip time.

• Check Citrix ADM for a breakdown of the ICA RTT to determine the root cause. For more information, see Citrix ADM documentation.
• If Citrix ADM is not available, check the Director User Details view for the ICA RTT and Latency, and determine if it is a network problem or an issue with applications or desktops.

ICA RTT (No. of Sessions)

Number of sessions that exceed the threshold ICA round-trip time.

• Check Citrix ADM for the number of sessions with high ICA RTT. For more information, see Citrix ADM documentation.

• If Citrix ADM is not available, work with the network team to determine the root cause.

  Smart policy conditions:

  • Scope: Delivery Group, Multi-session OS scope
  • Threshold values: Warning - 300 ms for 5 or more sessions, Critical - 400ms for 10 or more sessions

ICA RTT (% of Sessions)

Percentage of sessions that exceed the average ICA round-trip time.

• Check Citrix ADM for the number of sessions with high ICA RTT. For more information, see Citrix ADM documentation.
• If Citrix ADM is not available, work with the network team to determine the root cause.

ICA RTT (User)

ICA round-trip time that is applied to sessions launched by the specified user. The alert is triggered if ICA RTT is greater than the threshold in at least one session.

Failed Machines (Single-session OS)

Number of failed Single-session OS machines. Failures can occur for various reasons as shown in the Director Dashboard and Filters views.

• Run Citrix Scout diagnostics to determine the root cause.

  Smart policy conditions:

  • Scope: Delivery Group, Multi-session OS scope
  • Threshold values: Warning - 1, Critical - 2

Failed Machines (Multi-session OS)

Number of failed Multi-session OS machines. Failures can occur for various reasons as shown in the Director Dashboard and Filters views.

• Run Citrix Scout diagnostics to determine the root cause.

  Smart policy conditions:

  • Scope: Delivery Group, Multi-session OS scope
  • Threshold values: Warning - 1, Critical - 2

Failed Machines (in %)

The percentage of failed single-session and multi-session OS machines in a delivery group calculated based on the number of failed machines. This alert condition allows you to configure alert thresholds as a percentage of failed machines in a delivery group and is calculated every 30 seconds. Failures can occur for various reasons as shown in the Director Dashboard and Filters views. Run Citrix Scout diagnostics to determine the root cause. For more information, see Troubleshoot user issues.

Failed power on action and Failed Power off action

Number of failed power on actions and number of failed power off actions in a delivery group calculated based on number of Power Managed Machines that failed to power on or off. This alert condition allows you to configure alert thresholds as the number of Power Managed Machines that failed to power on or off in a delivery group and is calculated every 30 minutes.

Admin can configure the following parameters for these alerts in the Advanced alert policy:

• Triggered By: What triggered the power action
• Reason Of failure: Why the action failed
• Threshold: Threshold number of machines that failed power action to trigger the policy
• Sampling interval: The interval In which the failed power action has to be checked
• Re-alert interval: After how much time the alert must be re-sent

Failures can occur for various reasons as shown in the Director Dashboard and Filters views. Run Citrix Scout diagnostics to determine the root cause. For more information, see Troubleshoot user issues.

Unregistered machines (in %)

A machine is considered unregistered, when a machine becomes unstable due to a restart or when there is a communication problem between the delivery controller and the virtual machines. The Unregistered machines (in %) is the percentage of unregistered single-session and multi-session OS machines in a delivery group calculated based on the number of unregistered machines. This alert condition allows you to configure warning and critical threshold values as a percentage of unregistered machines in a delivery group. You can set an interval for re-alert. You can also add an email to get a notification when the conditions are met for Unregistered Machines (in %). When the critical or warning threshold value is exceeded, alerts and emails are generated. You can view alerts under Citrix Alerts. You can filter it by Unregistered Machines (in %) category and for the required state and time.

You can also receive alert details in a CSV attachment if there is an email or through a JSON payload if there is a webhook.

Note:

The critical value must be greater than the warning value.

Policy conditions:

• Scope: Single-session OS, and Multi-session OS Delivery group
• Threshold values: Warning and Critical

Machine uptime alert

Machine uptime in a delivery group is calculated based on the number of hours per day, hours per week, or hours per month for a machine that is turned on in a delivery group. This alert condition allows you to configure alert thresholds as the hours a machine is turned on in a delivery group. The machine uptime alerts works as follows in case of:

• Hours per day - You can specify the number of hours a machine is turned on for a day and is calculated every 30 minutes. The maximum number of hours per day that you can set is 24 hours.
• Hours per week - You can specify the number of hours a machine is turned on for a week and is calculated every six hours. The maximum number of hours per week that you can set is 168 hours.
• Hours per month - You can specify the number of hours a machine is turned on for a month and is calculated once every day. The maximum number of hours per month is 720 hours. The minimum re-alert interval value that you can set is 60 minutes. You can enter the number of machines that cross the machine uptime threshold value under the Warning and Critical alerts section. You can also add exceptions for any machines.

For example, if there are five delivery groups added for this alert and if in the first delivery group and fourth delivery group, the number of machines crosses the warning or critical threshold values, the alert is triggered separately for the first delivery group and for the fourth delivery group.

This alert helps the admins to analyze the uptime of the machines and based on this analysis the admins can help in optimizing the cost. You can also receive alert details in a CSV attachment if there is an email or through a JSON payload if there is a webhook.

Average Logon Duration

Average logon duration for logons that occurred over the last hour.

• Check the Director Dashboard to get up-to-date metrics regarding the logon duration. Many users logging in during a short timeframe can increase the logon duration.

• Check the baseline and break down of the logons to narrow down the cause. For more information, see Diagnose user logon issues

  Smart policy conditions:

  • Scope: Delivery Group, Multi-session OS scope
  • Threshold values: Warning - 45 seconds, Critical - 60 seconds

Logon Duration (User)

Logon duration for logons for the specified user that occurred over the last hour.

Load Evaluator Index

Value of the Load Evaluator Index over the last 5 minutes.

• Check Director for Multi-session OS Machines that might have a peak load (Max load). View both Dashboard (failures) and Trends Load Evaluator Index report.

  Smart policy conditions:

  • Scope: Delivery Group, Multi-session OS scope
  • Threshold values: Warning - 80%, Critical - 90%

Configure alerts policies with webhooks

Apart from email notifications, you can configure alerts policies with webhooks.

Note: This feature requires Delivery Controller(s) version 7.11 or later.

You can configure an alert policy with an HTTP callback or an HTTP POST using PowerShell cmdlets. They are extended to support webhooks.

For information on the creation of a new Octoblu workflow and obtaining the corresponding webhook URL, see the Octoblu Developer Hub.

To configure a webhook URL for a new alert policy or for an existing policy, use the following PowerShell cmdlets.

Create a new alerts policy with a webhook URL:

$policy = New-MonitorNotificationPolicy -Name <Policy name> -Description <Policy description> -Enabled $true -Webhook <Webhook URL>
<!--NeedCopy-->

Add a webhook URL to an existing alerts policy:

Set-MonitorNotificationPolicy - Uid <Policy id> -Webhook <Webhook URL>
<!--NeedCopy-->

For help on the PowerShell commands, use the PowerShell help, for example:

Get-Help  <Set-MonitorNotificationPolicy>
<!--NeedCopy-->

Notifications generated from the alert policy trigger the webhook with a POST call to the webhook URL. The POST message contains the notification information in JSON format:

{"NotificationId" : \<Notification Id\>,

"Target" : \<Notification Target Id\>,

"Condition" : \<Condition that was violated\>,

"Value" : \<Threshold value for the Condition\>,

"Timestamp": \<Time in UTC when notification was generated\>,

"PolicyName": \<Name of the Alert policy\>,

"Description": \<Description of the Alert policy\>,

"Scope" : \<Scope of the Alert policy\>,

"NotificationState": \<Notification state critical, warning, healthy or dismissed\>,

"Site" : \<Site name\>}
<!--NeedCopy-->

Hypervisor Alerts Monitoring

Director displays alerts to monitor hypervisor health. Alerts from XenServer and VMware vSphere help monitor hypervisor parameters and states. The connection status to the hypervisor is also monitored to provide an alert if the cluster or pool of hosts is rebooted or unavailable.

To receive hypervisor alerts, ensure that a hosting connection is created in Web Studio. For more information, see Connections and resources. Only these connections are monitored for hypervisor alerts.

These alerts are displayed once the thresholds are reached or exceeded. Hypervisor alerts can be:

• Critical—critical threshold of the hypervisor alarm policy reached or exceeded
• Warning—warning threshold of the hypervisor alarm policy reached or exceeded
• Dismissed—alert no longer displayed as an active alert

This feature requires Delivery Controller version 7 1811 or later. If you are using an older version of Director with sites 7 1811 or later, only the hypervisor alert count is displayed. To view the alerts, you must upgrade Director.

The following table describes the various parameters and states of Hypervisor alerts.

Note:

For more information about configuring alerts, see Citrix XenCenter Alerts or check the VMware vCenter Alerts documentation.

Email notification preference can be configured under Citrix Alerts Policy > Site Policy > Hypervisor Health. The threshold conditions for Hypervisor alert policies can be configured, edited, disabled, or deleted from the hypervisor only and not from Director. However, modifying email preferences and dismissing an alert can be done in Director. You can disable the alert if your role does not involve infrastructure monitoring.

Important:

• Alerts triggered by the Hypervisor are fetched and displayed in Director. However, changes in the life cycle/state of the Hypervisor alerts are not reflected in Director.
• Alerts that are healthy or dismissed or disabled in the Hypervisor console continues to appear in Director and have to be dismissed explicitly.
• Alerts that are dismissed in Director are not dismissed automatically in the Hypervisor console.
