Monitoring General Physical Resources

Use the Hosts view to monitor the physical resources of your cluster. These include the hosts and virtual machines. Please refer to the image below and the call-outs in it for more details.

Settings

Click the icon on the right side of the window to perform maintenance operations and modify specific settings on individual components.

Display control

• You can filter which components you want to display
  
• You can also control the ordering of each column in the display.

Display Logs

For each component you can view the log information. It is possible to filter the logs and search them.

	GSM Grid Service Manager. This is is a service grid component that manages a set of Grid Service Containers (GSCs). A GSM has an API for deploying/undeploying Processing Units. When a GSM is instructed to deploy a Processing Unit, it finds an appropriate, available GSC and tells that GSC to run an instance of that Processing Unit. It then continuously monitors that Processing Unit instance to verify that it is alive, and that the SLA is not breached.
	LUS Lookup Service. This service provides a mechanism for services to discover each other. Each service can query the lookup service for other services, and register itself in the lookup service so other services may find it.
	GSC Grid Service Container. This provides an isolated runtime for one (or more) processing unit (PU) instance and exposes its state to the GSM.
	Processing Unit This is the unit of packaging and deployment in the GigaSpaces Data Grid, and is essentially the main GigaSpaces service. The Processing Unit (PU) itself is typically deployed onto the Service Grid. When a Processing Unit is deployed, a Processing Unit instance is the actual runtime entity.
	Space Where GigaSpaces data is stored. It is the logical cache that holds data objects in memory and might also hold them in layered in tiering. Data is hosted from multiple SoRs, consolidated as a unified data model.
	Stateful PU This is a Space containing data and might also include code and services. They are displayed in all UI tools and the metrics for them are managed.
	Stateless PU Built-in services such as mirror WAN-GW, data GW and custom services. They are displayed in some UI tools (Ops-UI/Web-UI) but NOT in SpaceDeck. Metrics are managed.
	Mirror Performs the replication of changes to the target table or accumulation of source table changes used to replicate changes to the target table at a later time. If you have implemented bidirectional replication in your environment, mirroring can occur to and from both the source and target tables. Service
