have in its transmit queue before TIPC's congestion control mechanism is
activated.
.SS Monitor properties
.TP
.B threshold
.br
The threshold specifies the cluster size exceeding which the link monitoring
algorithm will switch from "full-mesh" to "overlapping-ring".
If set of 0 the overlapping-ring monitoring is always on and if set to a
value larger than anticipated cluster size the overlapping-ring is disabled.
The default value is 32.
.SS Monitor information
.TP
.B table_generation
.br
Represents the event count in a node's local monitoring list. It steps every
time something changes in the local monitor list, including changes in the
local domain.
.TP
.B cluster_size
.br
Represents the current count of cluster members.
.TP
.B algorithm
.br
The current supervision algorithm used for neighbour monitoring for the bearer.
Possible values are full-mesh or overlapping-ring.
.TP
.B status
.br
The node status derived by the local node.
Possible status are up or down.
.TP
.B monitored
.br
Represent the type of monitoring chosen by the local node.
Possible values are direct or indirect.
.TP
.B generation
.br
Represents the domain generation which is the event count in a node's local
domain. Every time something changes (peer add/remove/up/down) the domain
generation is stepped and a new version of node record is sent to inform
the neighbors about this change. The domain generation helps the receiver
of a domain record to know if it should ignore or process the record.
.TP
.B applied_node_status
.br
The node status reported by the peer node for the succeeding peers in
the node list. The Node list is a circular list of ascending addresses
starting with the local node.
Possible status are: U or D. The status U implies up and D down.
.TP
.B [non_applied_node:status]
.br
Represents the nodes and their status as reported by the peer node.
These nodes were not applied to the monitoring list for this peer node.
They are usually transient and occur during the cluster startup phase
or network reconfiguration.
Possible status are: U or D. The status U implies up and D down.
.SH EXAMPLES
.PP
tipc link monitor list
.RS 4
Shows the link monitoring information for cluster members on device data0.
.RE
.PP
tipc link monitor summary
.RS 4
The monitor summary command prints the basic attributes.
.RE
.SH EXIT STATUS
Exit status is 0 if command was successful or a positive integer upon failure.
