Bulkstats are only generated for the first 100 NAT IP pools from an alphabetical list of all NAT IP pools, which is based
on the context name and pool name. Therefore, to generate bulkstats for a specific NAT IP pool it must be named such
that it gets selected in the first 100 bulkstats.
on the context name and pool name. Therefore, to generate bulkstats for a specific NAT IP pool it must be named such
that it gets selected in the first 100 bulkstats.
The following are cumulative statistics that can be part of NAT bulkstats:
vpnname: Context name
realmname: Realm name
nat-bind-updates: Total interim AAA NBU sent
nat-rlm-bytes-tx: Total number of bytes transferred by realm (uplink + downlink)
nat-rlm-flows: Total number of flows used by the realm
nat-rlm-ip-denied: Total number of flows denied NAT IP address
nat-rlm-port-denied: Total number of flows denied NAT ports
nat-rlm-max-port-chunk-subs: Total number of subscribers who used maximum number of port chunks
nat-rlm-max-port-chunk-used: Maximum port chunks used
The following are snapshot statistics that can be part of NAT bulkstats:
vpnname: Context name
realmname: Realm name
nat-rlm-ttl-ips: Total number of NAT public IP addresses, per context per NAT realm. Is a static value.
nat-rlm-ips-in-use: Total number of NAT IP addresses currently in use, per context per NAT realm.
nat-rlm-current-users: Total number of subscribers currently using the NAT realm.
nat-rlm-ttl-port-chunks: Total number port-chunks, per context per NAT realm. Is a static value.
nat-rlm-chunks-in-use: Total number of port-chunks currently in use, per context per NAT realm.
nat-rlm-max-cur-port-chunk-subs: Current number of subscribers using maximum number of port chunks.
nat-rlm-max-cur-port-chunk-used: Maximum port chunks used by active subscribers.
nat-rlm-port-chunk-size: Size of the port chunk in the NAT realm.
nat-rlm-port-chunk-average-usage-tcp: Average TCP port usage in the allocated TCP ports, i.e. out of allocated
TCP ports how many got used. Not percentage value.
nat-rlm-port-chunk-average-usage-udp: Average UDP port usage in the allocated UDP ports, i.e. out of allocated
UDP ports how many got used. Not percentage value.
nat-rlm-port-chunk-average-usage-others: Average other (ICMP or GRE) port usage in the allocated other ports,
i.e. out of allocated ‗other‘ ports how many got used. Not percentage value.
Alarms
Alert threshold values can be specified to generate alarms for NAT IP pools. To specify realm-specific threshold limits
(pool-used, pool-free, pool-release, and pool-hold) ―alert-threshold‖ NAT IP pool parameter can be used, or it can also
be specified across context. These thresholds can be specified to any number of NAT IP pools.
