QUERY_NN_TOPOLOGY_STATS
node_equal_rsns
Total number of topology node updates received by this node with RSN equal to the current RSN. Both even
and odd RSNs are included in this count. (These TDUs are not errors, but result when TDUs are broadcast
to all adjacent network nodes. No update to this node’s topology database occurs.)
node_good_high_rsns
Total number of topology node updates received by this node with RSN greater than the current RSN. The
node updates its topology and broadcasts a TDU to all adjacent network nodes. It is not required to send a
TDU to the sender of this update because that node already has the update.
node_bad_high_rsns
Total number of topology node updates received by this node with an odd RSN greater than the current RSN.
These updates represent a topology inconsistency detected by one of the APPN network nodes. The node
updates its topology and broadcasts the TDU to all adjacent network nodes.
node_state_updates
Total number of topology node updates built as a result of internally detected node state changes that affect
APPN topology and routing. Updates are sent via TDUs to all adjacent network nodes.
node_errors
Total number of topology node update inconsistencies detected by this node. This occurs when this node
attempts to update its topology database and detects a data inconsistency. This node will create a TDU with
the current RSN incremented to the next odd number and broadcast it to all adjacent network nodes.
node_timer_updates
Total number of topology node updates built for this node’s resource due to timer updates. Updates are sent
via TDUs to all adjacent network nodes. These updates ensure that other network nodes do not delete this
node’s resource from their topology database.
node_purges
Total number of topology node records purged from this node’s topology database. This occurs when a node
record has not been updated in a specified amount of time. The owning node is responsible for broadcasting
updates for its resource that it wants kept in the network topology.
tg_low_rsns
Total number of topology TG updates received by this node with RSN less than the current RSN. Both even
and odd RSNs are included in this count. (These TDUs are not errors, but result when TDUs are broadcast
to all adjacent network nodes. No update to this node’s topology database occurs, but this node will send a
TDU with its higher RSN to the adjacent node that sent this low RSN.)
tg_equal_rsns
Total number of topology TG updates received by this node with RSN equal to the current RSN. Both even
and odd RSNs are included in this count. (These TDUs are not errors, but result when TDUs are broadcast
to all adjacent network nodes. No update to this node’s topology database occurs.)
tg_good_high_rsns
Total number of topology TG updates received by this node with RSN greater than the current RSN. The
node updates its topology and broadcasts a TDU to all adjacent network nodes.
tg_bad_high_rsns
Total number of topology TG updates received by this node with an odd RSN greater than the current RSN.
These updates represent a topology inconsistency detected by one of the APPN network nodes. The node
updates its topology and broadcasts the TDU to all adjacent network nodes.
tg_state_updates
Total number of topology TG updates built as a result of internally detected node state changes that affect
APPN topology and routing. Updates are sent via TDUs to all adjacent network nodes.
