Cluster Manager statistics
Other than AvailabilityIndex, AvailabilityThreshold, and ExpansionFactor, each Domino® cluster manager statistics name includes the prefix Server.Cluster, which is not included in the names in this table. AvailabilityIndex, AvailabilityThreshold, and ExpansionFactor include the prefix Server.

Table 1. Statistic names
Statistic nameDescription
MemberShows the names and the availability indexes of the servers in the cluster
AvailabilityIndexA measure of a server's availability. 0 (zero) indicates no available resources; 100 indicates complete server availability
AvailabilityThresholdThe 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.
ExpansionFactorThe 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.SuccessfulTotal times that server successfully redirects a client to another cluster member after the client fails to open a database by replica ID
OpenRedirects.Failover.UnsuccessfulTotal 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.SuccessfulTotal times server successfully redirects a client to another cluster member after the client fails to open a database by path name
OpenRedirects.FailoverByPath.UnsuccessfulTotal 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.SuccessfulTotal 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.UnsuccessfulTotal 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.UnsuccessfulTotal 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.SuccessfulTotal 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.ClusterBusyTotal client requests when all servers are BUSY
OpenRequest.DatabaseOutOfServiceTotal times a client tries to open a database that is marked out-of-service on the server
OpenRequest.LoadBalancedTotal times a client tries to open a database on the server when the server is BUSY
PortNameDefault 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
ProbeCountTotal times that a server completes a probe of the other cluster members
ProbeErrorTotal times that a server receives an error when probing another server
ProbeTimeout(mins) Shows the interval at which an intracluster probe occurs
