eG Monitoring
 

Measures reported by VDIBoxServerTest

The grid unites servers running vdiManager, allowing load balancing and ensuring high availability of virtual machines on the servers. Servers are organized into a grid, and all the servers in a grid are functionally identical, so if one dies any of the others act in its place. For each server in the monitored grid, this test reports the current status of that server, the server configuration, the status of the virtual desktops on the server, and the disk space utilization on the server, so that:

  • Inactive servers in the grid can be quickly identified;
  • Servers experiencing a space crunch can be isolated;
  • The number of desktops in various states of usage/activity can be ascertained

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
State Indicates the current status of this server. Number If the server is an active server in the grid, this measure will report the value Activated. If the server is an inactive server in the grid, this measure will report the value Deactivated. The values that this measure can take and their corresponding numeric values are discussed in the table below:
Measure Value Numeric Value
Activated 1
Deactivated 0
Quiescing 2
Deactivating 3
Shutting Down 4
Shutdown 5
Missing 6
Broken 7

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the current status of a server. However, in the graph of this measure, the status will be represented using the corresponding numeric equivalents only.

Desk_in_use Indicates the number of desktops on this server that are currently in use. Number  
Desk_in_hold Indicates the number of desktops on this server that have been preserved for subsequent use. Number This refers to the number of desktops that are ‘On Hold’.
Desk_new Indicates the number of desktops on this server that are already prestarted for instant login. Number Pre-started desktops are in a powered-on state and at the logon prompt, ready for use. Pre-starting desktops eliminates the need for users to wait for virtual desktops to start.
Desk_start Indicates the number of desktops on this server that are being pre-started for instant login. Number
Server_type Indicates the type of this server.   The values that this measure can take and their corresponding numeric values are discussed in the table below:

Measure Value Numeric Value
VMware 1
XenServer 2
Hyper-V 3

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the server type. However, in the graph of this measure, the type will be represented using the corresponding numeric equivalents only.

If you have added a server of a different type, say XenServer, to a grid of servers of type VMware, then this measure will reveal this inconsistency.
Ram_size Indicates the total RAM size of this server. MB  
Num_CPU_core Indicates the number of CPU cores of this server. Number  
Total_CPU Indicates the total CPU cycles available across all CPU cores in the server. GHz  
Disk_total Indicates the total capacity of the logical storage device attached to this server. GB  
Disk_free Indicates the amount of unused space in the logical storage device of this server. GB A high value is desired for this measure.
Disk_used Indicates the amount of space that is currently in use on the logical storage device of this server. GB A very high value is a cause for concern, as it indicates that the server is running short of storage space. Without sufficient space, critical read/write operations cannot be performed by the server. You may then have to clear some space in the logical storage devices or allocate more space to these devices to avert the problem.
Disk_util Indicates the percentage of space in the logical storage device of this server that is currently in use. Percent
