Windows Cluster Monitoring

Monitored Parameters

Applications Manager's Windows Cluster monitoring capability includes monitoring of the cluster details, the cluster nodes, resource groups, cluster performance, networks, disk utilization and storage stats. You can also monitor the cluster events by configuring the Event log Rules.

The monitoring details of Windows Cluster are represented graphically that helps to understand the parameters with ease. You can also configure thresholds to the attributes monitored and in case of threshold violation you can get notified on this by associating Actions. This will also help, to get notified on the failover happened in the Cluster.

Availability tab, gives the Availability history for the past 24 hours or 30 days. Performance tab gives the Health Status and events for the past 24 hours or 30 days. List view enables you to perform bulk admin configurations. Click on the individual monitors listed, to view the following information.

The Windows Cluster attributes monitored are classified under the following tabs in Applications Manager:

Down - The node is turned off or not operational. Joining - The node is in the process of joining a cluster. Paused - The node is running but not participating in cluster operations. Unknown - The operation was not successful.
RESOURCE CONTROL AND MULTICAST RR

RHS Processes	Specifies how many Resource Host Monitor processes are running on the node.
RHS Restarts	Specifies how many Resource Host Monitor failures have taken place on this node.
NETWORK RECONNECTIONS
Reconnect Count	Specifies the number of times the TCP connection was broken and reestablished.

Performance

Parameter	Description
MULTICAST REQUEST REPLY

Normal Message Queue Length Delta	Specifies the incoming message rate to the queue.
Urgent Message Queue Length	Specifies the number of urgent messages in the queue waiting to be sent.
Urgent Message Queue Length Delta	Specifies the incoming message rate to the queue.
RESOURCE TYPE STATS
Resource Failure	Indicates the number of times, the Resource Host Monitor get terminated due to a failure of a resource.
Resource Failure Access Violation	Indicates the number of times, the Resource Host Monitor get terminated due to a failure of a resource, which caused by access violation.
Resource Failure Deadlock	Indicates the number of times, the Resource Host Monitor get terminated due to a failure of a resource, which caused by deadlock.

Networks

Parameter	Description
Name	Specifies the name of the network.
Address	Provides the address for the entire network or subnet.
Role	Provides access to the network's Role property i.e, the role of the network in the cluster. The following are the possible values: None - The network is not used by the cluster. Cluster - The network is used to carry internal cluster communication. Client - The network is used to connect client systems to the cluster. Both - The network is used to connect client systems and to carry internal cluster communication.
State	Specifies the current state of the network. The following are the possible values: Unknown - The operation was not successful. Unavailable - All of the network interfaces on the network are unavailable, which means the nodes that own the network interfaces are down. Down - The network is not operational; none of the nodes on the network can communicate. Partitioned - The network is operational, but two or more nodes on the network cannot communicate. Typically a path-specific problem has occurred. Up - The network is operational; all of the nodes in the cluster can communicate.
NETWORK MESSAGES
Bytes Received	The Bytes Received/sec performance counter shows the number of new cluster message bytes received on the network per second
Bytes Sent	The Bytes Sent/sec performance counter shows the number of new cluster message bytes sent over the network per second.
Messages Received	The Messages Received/sec performance counter shows the number of new cluster messages received on the network per second.
Messages Sent	The Messages Sent/sec performance counter shows the number of new cluster messages sent over the network per second.

Storage

Parameters	Description
Path	The path (including the drive letter if present) of the clustered disk partition.
Volume Label	Specifies access to the VolumeLabel property, which is the volume label of the partition.
Size	The total size for the partition, in megabytes.
Used	The total used space in the partition, in megabytes.
Free	The total free space available for the partition, in megabytes.
Used Percentage	The percentage of used space in the partition.
Free Percentage	The percentage of free space in the partition.

Resource Groups

Parameters	Description
Name	The name of the Resource group.
Current Node	The node in which the resource group is currently running.
