Linux VM and Linux session metrics

The following table lists some metrics that are available for Linux VMs and Linux sessions.

Metric Min. VDA Version Required Description Remarks
ICA latency 2311 ICA Latency is basically the network latency. This metric indicates if the network is sluggish. To access this metric, open the Session Details view. Available both in Citrix Director and in Monitor.
Policies 2311 All policies that are in effect for the current session are displayed on the Policies tab in the Session Details view. Available both in Citrix Director and in Monitor.
Logon duration 2109 It is a measure of the logon process from the time a user connects from Citrix Workspace app to the time a session is ready to use. To view the metric of a session, go to the Monitor tab of Citrix DaaS (formerly Citrix Virtual Apps and Desktops service). Monitor is available as the Director console to monitor and troubleshoot Citrix Virtual Apps and Desktops Current Release and LTSR deployments. On the Monitor tab, click View Historical Trend in the Average Logon Duration section. On the Logon Performance page, set filter conditions and click Apply to visualize metrics. Available only in Monitor.
Session auto reconnect count 2109 To view the number of auto reconnects in a session, access the Trends view. Set conditions and click Apply to narrow search results. The Session Auto Reconnect Count column displays the number of auto reconnects in a session. Auto reconnect is enabled when the Session Reliability or the Auto Client Reconnect policies are in effect. For more information about session reconnections, see Sessions. For more information about policies, see Auto client reconnect policy settings and Session reliability policy settings Available both in Citrix Director and in Monitor.
Idle time 2103 To access this metric, open the All Sessions page by selecting Filters > Sessions > All Sessions. Available both in Citrix Director and in Monitor.
Metrics of a Linux VM 2103 The following metrics for Linux VMs are available: the number of CPU cores, memory size, hard disk capacity, and current and historical CPU and memory utilization Available both in Citrix Director and in Monitor.
Protocol 1909 The transport protocol of a Linux session appears as UDP or TCP in the Session Details view. Available both in Citrix Director and in Monitor.
ICA RTT 1903 ICA Round Trip Time (RTT) is the elapsed time from when you press a key until the response appears on the endpoint. To obtain ICA RTT metrics, create the ICA round trip calculation and ICA round trip calculation interval policies in Citrix Studio. Available both in Citrix Director and in Monitor.

Examples of how to access the various metrics in Citrix Director and Monitor

  • Logon duration

    1. On the Monitor tab of Citrix DaaS, click View Historical Trend in the Average Logon Duration section.

      Click View Historical Trend

    2. On the Logon Performance page, set filter conditions.

      Set filter conditions

    3. Click Apply to visualize the logon duration metrics.

  • The number of CPU cores, memory size, hard disk capacity, and current and historical CPU and memory utilization of a Linux VM

    To access these metrics of a Linux VM, find the VM in Citrix Director or Monitor and check the Machine Details view. For example:

    Linux VM metrics - 1

    Linux VM metrics - 2

  • ICA RTT, ICA latency, Protocol, Policies

    To view the metrics of a Linux session, open the All Sessions page by selecting Filters > Sessions > All Sessions, or access the Session Details view. To access the Session Details view, open the All Sessions page and click a target session to access its Activity Manager view. For example:

    The Session Details view

  • Session auto reconnect count

    To view the number of auto reconnects in a session, access the Trends view. Set conditions and click Apply to narrow search results.

    The Session Auto Reconnect Count column displays the number of auto reconnects in a session. For example:
