Configuring Power and Capacity Management

Oct 09, 2015

After component installation, first-time use of the Power and Capacity Management system includes specifying configuration values. With a basic setup (using default setpoint values and without enabling load consolidation or power management), you can monitor the system and create reports.

Complete the following Initial configuration tasks:
  • Connect to a XenApp Power and Capacity Management farm to manage (required only if you have more than one Power and Capacity Management farm)
  • Configure server profile properties
  • Configure server properties
  • Specify global configuration settings
  • Add machine managers, if your Power and Capacity Management farm includes XenApp servers hosted on XenServer virtual machines
  • Optionally, add sites, if your Power and Capacity Management farm includes XenApp servers hosted on XenServer virtual machines
After the initial setup, observe management console displays and generate reports. Using the collected information, you can then:
  • Create a schedule
  • Enable power management and load consolidation

Understanding management console displays

The management console connects to the master concentrator to obtain data. The menu, toolbars, and Actions pane are standard MMC 3.0 panes, some of which can be hidden if required. The workloads and tabs panes comprise the Power and Capacity Management snap-in.

The workloads pane contains the following information:
Column Description
Workload All Workloads, plus names of individual workloads
Power Managed Indicates if power management is enabled or disabled for the system (All Workloads) and for each workload.
  • Checkmark = enabled ("override" indicates a manual override is in effect)
  • x = disabled (with a notation if a workload does not have a schedule)
Load Consolidated Indicates if load consolidation is enabled or disabled for the system (All Workloads) and for each workload.
  • Checkmark = enabled
  • x = disabled
Utilization Current utilization shown in meter form and percent text (utilization is the ratio of: total active sessions/total session capacity available from all online servers)
Sessions Current number of load, unused, and offline sessions, shown graphically and in absolute counts.
Servers Current number of online and offline servers in the workload, shown graphically and in absolute counts.

The tabs pane contains five tabs.

Status
Utilization, sessions, and servers information on the Status tab is equivalent to the information for the selected workload in the workloads pane above it.
  • When All Workloads is selected, the Status display also indicates if power management and load consolidation are globally enabled or disabled.
  • When a single workload is selected, the Status display also indicates if power management and workload load consolidation are enabled or disabled for that workload.
With power management enabled, the display includes current setpoint values.
  • For workloads with an empty schedule and no override, the display shows the default setpoint values
  • When the power controller is following the schedule for a workload, the display shows the scheduled setpoint values
  • When the power controller is following override setpoints for a workload, the display shows those values
Performance
The Performance tab displays metric graphs collected for a specific interval. After you select an interval, the display shows values collected throughout the interval for utilization, sessions, and servers, starting with the beginning of the selected interval, and ending with the current ("Now") value.
Servers
The Servers tab lists all servers in the workload selected in the workloads pane. Information for each server includes:
Column Content

Server

DNS name and server profile information.

Control mode

Power control mode, site (if there is more than one defined), and power controller preference.

State

Online, offline, draining, powering on, or powering off. If you disable logons to a server, this field indicates Maintenance.

Utilization

Current utilization percentage in graphic and text forms.

Sessions

Current sessions counts in graphic and text forms.

Hovering over an entry displays the current session count for that server and the current load consolidation activity, if any. An icon to the left of the graph represents the current load consolidation activity (when load consolidation is enabled for the server's workload):
  • Green triangle = server is accepting new connections and is below optimal load
  • Yellow triangle = server is accepting new connections but is above optimal load
  • Grey dot = logons are disabled for this server

The Sessions graphic fades for servers in drain mode.

Session Capacity

Hovering over an entry displays how the dynamic capacity estimate differs from the typical session capacity value configured in the server profile (the session capacity value indicates 'calculated').

Capacities
The Capacities tab displays server profile information and the typical session capacity for each server profile (or Unset if the typical session capacity has not been configured). To display the DNS names of servers that use a profile, select the profile, then click the entry in the Servers column.
Schedule
The Schedule tab displays the current Monday through Sunday schedule for a workload. (This tab is not displayed when All Workloads is selected in the workloads pane.) The entry for each day indicates time and setpoint values.
