| Statistic name | Description |
| Member | Shows the names and the availability indexes of the servers in the cluster |
| AvailabilityIndex | A measure of a server's availability. 0 (zero) indicates no available resources; 100 indicates complete server availability |
| AvailabilityThreshold | The current availability threshold of the server. When the availability index is less than or equal to the availability threshold, the server is put into the BUSY state. |
| ExpansionFactor | The current expansion factor. This value is used to compute the availability index. A value of 1 indicates that the server is completing transactions at the minimum time for that server. A value of 64 indicates that it is taking 64 times longer than the minimum time to complete transactions. By default, an expansion factor of 64 indicates a fully loaded server, and results in an availability index of 0 (zero). You can use the NOTES.INI setting Server_Transinfo_Range to change the expansion factor value that indicates a fully loaded server. |
| OpenRedirects.Failover.Successful | Total times that server successfully redirects a client to another cluster member after the client fails to open a database by replica ID |
| OpenRedirects.Failover.Unsuccessful | Total times that server is unable to redirect a client to another cluster member after the client fails to open a database by replica ID |
| OpenRedirects.FailoverByPath.Successful | Total times server successfully redirects a client to another cluster member after the client fails to open a database by path name |
| OpenRedirects.FailoverByPath.Unsuccessful | Total times server is unable to redirect a client to another cluster member after the client fails to open a database by path name |
| OpenRedirects.LoadBalance.Successful | Total times server successfully redirects a client to another cluster member after the client tries to open a database by replica ID when the server is BUSY |
| OpenRedirects.LoadBalance.Unsuccessful | Total times server is unable to redirect a client to another cluster member after the client tries to open a database by replica ID when the server is BUSY |
| OpenRedirects.LoadBalanceByPath.Unsuccessful | Total times that server is unable to redirect a client to another cluster member after the client tries to open a database by path name when the server is BUSY |
| OpenRedirects.LoadBalanceByPath.Successful | Total times that server successfully redirects a client to another cluster member after the client tries to open a database by path name when the server is BUSY |
| OpenRequest.ClusterBusy | Total client requests when all servers are BUSY |
| OpenRequest.DatabaseOutOfService | Total times a client tries to open a database that is marked out-of-service on the server |
| OpenRequest.LoadBalanced | Total times a client tries to open a database on the server when the server is BUSY |
| PortName | Default port used for intra-cluster network traffic or an asterisk, which indicates there is no default port and any available active port can be used |
| ProbeCount | Total times that a server completes a probe of the other cluster members |
| ProbeError | Total times that a server receives an error when probing another server |
| ProbeTimeout(mins) | Shows the interval at which an intracluster probe occurs
