connection-count |
Number of connections for a cluster link |
connection-creation-rate , connection-creation-total |
Rate per second and total for connections created for the cluster link. If the rate is high, the source cluster may be overloaded with connections. |
connection-close-rate , connection-close-total |
Rate per second and total for connections closed for the cluster link. Can be compared to connection creation to understand the balance of creating/closing connections. |
incoming-byte-rate , incoming-byte-total |
Number of bytes per second and total received from the source cluster. |
outgoing-byte-rate , outgoing-byte-total |
Number of bytes per second and total sent to the source cluster. |
network-io-rate , network-io-total |
Indicates rate and total network input/output (IO). |
request-rate , request-total |
Rate per second and total requests issued to the source cluster over the cluster link. |
response-rate , response-total |
Rate per second and total number of responses received from the source cluster over the cluster link. |
request-size-avg , request-size-max |
Average and maximum size in bytes of requests issued to the source cluster over the cluster link. |
io-ratio , io-wait-time-ns-avg , io-waittime-total , iotime-total |
Statistics of the destination cluster’s network IO for the requests over the cluster link. |
successful-authentication-rate , successful-authentication-total |
Rate per second and total number of cluster link clients authenticating to the source cluster over the cluster link. |
successful-reauthentication-rate , successful-reauthentication-total |
Rate per second and total re-authentication to the source cluster over the cluster link. |
failed-reauthentication-rate , failed-reauthentication-total |
Rate per second and total failed re-authentications to the source cluster over the cluster link. If failures are present, it could indicate misconfigured or stale cluster link credentials. |
reauthentication-latency-avg |
Average re-authentication latency. Helps to assess whether clients are taking too long to authenticate to the clusters. |
