Performance Metrics for Windows Failover Cluster
Get the number and status of all the nodes in a Windows cluster, network reconnections, storage stats, and state of the resource groups. The cluster monitor uses the Site24x7 Windows agent for monitoring. Install the Windows agent and get your failover clusters auto-discovered.
Once the failover cluster monitor is successfully added to your Site24x7 account,
- View performance metrics for cluster monitors. Log in to Site24x7 and go to Server > Microsoft Failover Cluster.
- Add a Threshold and Availability profile to declare a specific resource as critical or down. Go to Admin > Configuration Profiles > Threshold and Availability (+).
- Analyze trends and identify performance issues with exclusive performance reports.
- View key metrics in a single glance with the server inventory and health dashboards, or create your own.
Interpret Microsoft Failover Cluster Performance Metrics
The following metrics are provided for the Failover Cluster monitor:
- Cluster View: Details on the number of nodes, networks, online and offline resource groups are listed.
- Performance: Metrics related to resource stats and network messages communicated.
- Networks: Name, address, status of the network, along with bytes received/sent per second are specified.
- Storage: Data on the cluster disk including free space, used space, and total space available are tabulated.
- Resource Groups: Name, status, and the nodes in which the resource group is running are given.

| Resource Failure | The number of times the Resource Host Subsystem gets terminated due to a resource failure |
| Resource Failure Access Violation | Indicates the number of times the Resource Host Subsystem gets terminated due to a resource failure, caused by access violation |
| Resource Failure Deadlock | Indicates the number of times the Resource Host Subsystem gets terminated due to a resource failure, caused by a deadlock |
Networks
| Parameters | Description |
| Networks: | |
| Name | Name of the network |
| Address | Gives the address for the entire network or subnet |
