monCIPCMesh gives summary figures for the mesh of connections, from the current instance to all other instances in the cluster, on a per-instance basis. This monitoring table is available only for Adaptive Server Cluster Edition.
One row is returned for each of the four connections to each of the other nodes in the cluster, up to the maximum configured. If the system view is cluster, a set of rows for each instance active in the cluster is returned.
You need not enable any configuration parameters for
this monitoring table to collect data.
