- In the Health Monitors area, you can assign the GTP monitor to the server by moving it from theAvailablelist to theSelectedlist; however, best practice is to assign theGTPmonitor to the pool of PGW systems.The GTP monitor simply checks that the PGW system responds to a GTP echo request.
- In theHealth Monitorssetting, assign health monitors to the server by moving them from theAvailablelist to theSelectedlist.If the server is a BIG-IP system, use thebigipmonitor. If the server is a generic host, consider using thegateway_icmpmonitor, because this monitor simply checks that the server responds to a ping.

- From theLimit Settingslist, select the resource thresholds for this server.When the server does not meet the resource threshold limit requirements that you set, the system marks the server as unavailable and load balances traffic to available servers.The limit settings that display are based on the type of server you selected from theProductlist.CPUSpecifies the percent of CPU usage. If percent of CPU usage goes above the limit, the system marks the server as unavailable.MemorySpecifies the available memory required by the virtual servers on the server. If available memory falls below this limit, the system marks the server as unavailable.BitsSpecifies the maximum allowable data throughput rate, in bits per second, for the virtual servers on the server. If the network traffic volume exceeds this limit, the system marks the server as unavailable.PacketsSpecifies the maximum allowable data transfer rate, in packets per second, for the virtual servers on the server. If the network traffic volume exceeds this limit, the system marks the server as unavailable.Current ConnectionsSpecifies the maximum number of concurrent connections, combined, for all of the virtual servers on the server. If the connections exceed this limit, the system marks the server as unavailable.
- In theiQuery Optionssetting, specify the types of probes the DNS performs to determine the state of the server .The default is for the Global Traffic Manager to perform all three probes.If the server is another BIG-IP system, such as a Local Traffic Manager, then the Global Traffic Manager can delegate certain probe tasks to that system.Service CheckThe system verifies that an application on a server is running, by remotely running the application using an external service checker program.PathThe system verifies the logical network route between a data center server and a local DNS server.SNMPThe system checks the performance of a server running an SNMP agent.
- From theVirtual Server Discoverylist, select how you want virtual servers to be added to the system.DisabledThe system does not use the discovery feature to automatically add virtual servers. This is the default value. Use this option for a standalone BIG-IP DNS system or for a BIG-IP DNS/LTM combo system when you plan to manually add virtual servers to the system, or if your network uses multiple route domains.EnabledThe system uses the discovery feature to automatically add and delete virtual servers. Use this option for a BIG-IP DNS/LTM combo system when you want the BIG-IP DNS system to discover LTM virtual servers.Enabled (No Delete)The system uses the discovery feature to automatically add virtual servers and does not delete any virtual servers that already exist in the configuration. Use this option for a BIG-IP DNS/LTM combo system when you want the BIG-IP DNS system to discover LTM virtual servers.
- From theVirtual Server Discoverylist, select how you want virtual servers to be added to the system.Virtual server discovery is supported when you have only one route domain.DisabledUse this option when you plan to manually add virtual servers to the system, or if your network uses multiple route domains. This is the default value.EnabledThe system automatically adds virtual servers using the discovery feature.Enabled (No Delete)The system uses the discovery feature and does not delete any virtual servers that already exist.
- From theVirtual Server Discoverylist, selectEnabled.
- From theVirtual Server Discoverylist, selectEnabled (No Delete).
- From theVirtual Server Discoverylist, selectDisabled.
- From theLink Discoverylist, select how you want links to be added to the system.DisabledThe system does not use the discovery feature to automatically add links. This is the default value. Use this option for a standalone BIG-IP DNS system or for a BIG-IP DNS/LTM combo system when you plan to manually add links to the system.EnabledThe system uses the discovery feature to automatically add and delete links. Use this option for a BIG-IP DNS/LTM combo system when you want BIG-IP DNS to discover links.Enabled (No Delete)The system uses the discovery feature to automatically add links and does not delete any links that already exist in the configuration. Use this option for a BIG-IP DNS/LTM combo system when you want BIG-IP DNS to discover links.
