monCIPCMesh

Description

(Cluster environments only) Gives summary figures for the mesh of connections, from the current instance to all other instances in the cluster, on a per-instance basis.

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.

Description

InstanceID

tinyint

ID of the instance within the cluster.

FarInstanceID

tinyint

Instance number of the far-end instance in the cluster.

Received

int

Number of messages received by this instance from the FarInstanceID instance.

Dropped

int

Number of messages from the FarInstanceID instance that were dropped, due to a lack of resources.

Transmitted

int

Number of messages transmitted to the FarInstanceID instance.

Resent

int

MaxSendQ

int

Maximum number of packets in the send queue for this mesh since the InstanceID instance was started.

SentQ

int
