Dashboard

You can view the Status, Messages, and Network Resources on the Dashboard.

Status

You can view:

• Grid status, such as account, AppLogic version, system status, system uptime, high availability, and number of active applications with the grid resources by hypervisor type and total resources
• High availability status that indicates the ability of the grid to failover safely
• Number of applications currently running and their reserved resources
• Meters indicating the utilization of the grid's CPU, Memory, Storage, and Bandwidth resources.

  In addition, you can view the CPU oversubscription indicator, as applicable. The CPU resource can be over-subscribed to allow a grid to run applications whose CPU allocation exceeds the physical capacity of the grid.

  This gives service providers the ability to maximize their margins by controlling the level of CPU oversubscription. CPU oversubscription is used primarily where the appliances are not expected to be under full load all the time and can tolerate lower performance in case all appliances on the server are in use.

  When CPU oversubscription is configured, the CPU meter displays the virtual CPU capacity of the grid and an indicator beneath the meter showing the physical CPU capacity of the grid.

  Notes:

  • CPU oversubscription removes the guarantee of CPU resource allocation.
  • When using CPU oversubscription, applications should be started in round robin mode.
  • If you notice performance issues in applications on grids that use overcommit, app start does support a --no_overcommit option on a per-application basis. This allows you to start a specific application without overcommit, such as 2 CPU means 2 physical cores will be allocated. You can diagnose performance issues and rule out overcommit.

  For additional information on setting oversubscription, refer to grid set in the Grid Control section of the Command Line Shell Reference Guide.

• Oversubscription indicates the network bandwidth oversubscription status. If oversubscription is set in the command line, the resource meters display the overcommitment.

  Oversubscription of network bandwidth allows you to start a mix of applications whose network bandwidth requirement exceeds the network bandwidth capacity of the grid. Applications tend not to continually use full capacity of their network interfaces, allowing oversubscription to typically be safe.

Messages

• System maintenance messages

Network Resources

• Network settings for the grid, displaying application IP ranges separately for each VLAN. Information includes the name and number of VLAN, Application IP range, prefix, gateway, and name servers. The network list is both sortable and scrollable.
