Measures reported by WLClusterTest
This test extracts cluster related
statistics from a managed WebLogic server that is part of a cluster. Server
instances in a cluster communicate with each other using
multicasts—multicasts help the server instances in a cluster announce their
services, and issue periodic heartbeats that indicate continued
availability.

Measurement
Unit |
Interpretation |
| Alive_servers_count |
Number
of servers in the clusters that are running currently |
Number |
Ideally
this number must be equal to the actual number of servers in the
cluster. |
| Fragments_sent_rt |
The
rate of multicast fragments sent from this server into the
cluster |
Fragments/Sec |
|
| Fragments_received_rt |
Returns
the rate of multicast messages received on this server from
the cluster |
Fragments/Sec |
|
| Fragments_dropped_rt |
Indicates
the rate of fragments that originated in foreign domains/clusters
that use the same multicast address |
Fragments/Sec |
|
| Msgs_lost_rt |
Returns
the rate at which incoming multicast messages were lost |
Msgs/Sec |
|
| Resend_requests_rt |
Returns
the rate of state-delta messages that had to be resent because a
receiving server in the cluster missed a message |
Reqs/Sec |
|
| Primary_count |
Returns
the number of objects that the local server hosts as primaries |
