node_purges
Total number of topology node records purged from this node’s topology database. A purge 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 occur when TDUs are broadcast to all adjacent network nodes. This node’s topology database is not updated, 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 occur when TDUs are broadcast to all adjacent network nodes. This node’s topology database is not updated.
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. TG updates are sent via TDUs to all adjacent network nodes.
tg_errors
Total number of topology TG update inconsistencies detected by this node. A TG update inconsistency occurs when this node attempts to update its topology database and detects a data inconsistency. This node creates a TDU with the current RSN increased to the next odd number and broadcasts it to all adjacent network nodes.
tg_timer_updates
Total number of topology TG updates built for this node’s resource due to timer updates. TG 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.
tg_purges
Total number of topology TG records purged from this node’s topology database. A purge occurs when a TG 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.
total_route_calcs
Number of routes calculated for all class of services since the last initialization.
total_route_rejs
Number of route requests for all class of services that could not be calculated since the last initialization.
total_tree_cache_hits
Number of route computations that were satisfied by a cached routing tree. This number may be greater than the total number of computed routes because each route may require the inspection of several trees.
total_tree_cache_misses
Number of route computations that were not satisfied by a cached routing tree, so that a new routing tree had to be built.
