  53. In the Health Monitors area, you can assign the GTP monitor to the server by moving it from the
    Available
    list to the
    Selected
    list; however, best practice is to assign the
    GTP
    monitor to the pool of PGW systems.
    The GTP monitor simply checks that the PGW system responds to a GTP echo request.
  54. In the
    Health Monitors
    setting, assign health monitors to the server by moving them from the
    Available
    list to the
    Selected
    list.
    If the server is a BIG-IP system, use the
    bigip
    monitor. If the server is a generic host, consider using the
    gateway_icmp
    monitor, because this monitor simply checks that the server responds to a ping.
  55. In the
    Health Monitors
    setting, assign the
    bigip
    monitor to the server by moving it from the
    Available
    list to the
    Selected
    list.
  56. In the Health Monitors area, assign an SNMP monitor to the server by moving it from the
    Available
    list to the
    Selected
    list.
  57. In the Health Monitors area, assign the
    http
    monitor to the server by moving it from the
    Available
    list to the
    Selected
    list.
  58. From the
    Availability Requirements
    list, select an option and enter any required values.
    All Health Monitors
    By default, specifies that all of the selected health monitors must be successful before the server is considered up (available).
    At Least
    The minimum number of selected health monitors that must be successful before the server is considered up.
    Require
    The minimum number of successful probes required from the total number of probers requested.
  59. From the
    Limit Settings
    list, 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 the
    Product
    list.
    CPU
    Specifies the percent of CPU usage. If percent of CPU usage goes above the limit, the system marks the server as unavailable.
    Memory
    Specifies 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.
    Bits
    Specifies 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.
    Packets
    Specifies 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 Connections
    Specifies 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.
  60. In the
    iQuery Options
    setting, 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 Check
    The system verifies that an application on a server is running, by remotely running the application using an external service checker program.
    Path
    The system verifies the logical network route between a data center server and a local DNS server.
    SNMP
    The system checks the performance of a server running an SNMP agent.
  61. From the
    Virtual Server Discovery
    list, select how you want virtual servers to be added to the system.
    Disabled
    The 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.
    Enabled
    The 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.
  62. From the
    Virtual Server Discovery
    list, select how you want virtual servers to be added to the system.
    Virtual server discovery is supported when you have only one route domain.

    Enabled
    The 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.
  63. From the
    Virtual Server Discovery
    list, select
