Monitoring the NetApp Cluster

eG Enterprise provides out-of-the-box monitoring for the NetApp Cluster. The NetApp Cluster monitoring model (see Figure 1) offered by the eG Enterprise monitors various aspects of the performance of the NetApp Cluster and promptly alerts storage administrators to potential I/O processing bottlenecks or space crunches.

The metrics so collected report on the following:

• The performance of the hardware compoennts of the cluster;
• The health of the network components that interface with (and depend on) the hardware;
• The current status and space usage of physical storage entities (disks, aggregates etc);
• The efficiency of the access framework and protocols that are used to access the cluster – e.g., iSCSI;
• The NAS aspect of the NetApp Cluster; this includes the file access protocols such as CIFS;
• Abnormalities related to the usage of logical storage entities (such as volumes, LUNs, Qtrees etc.,) which are accessed using their framework by the end users;
• The overall status and performance of the NetApp Cluster which depends on all its underlying components;
• The failover state of the NetApp Cluster;
