Load Balancer: A10 Discovery identifies and classifies information about A10 load balancers. Prerequisites and important information Important: Discovery treats hardware load balancers as network devices and attempts to discover them primarily using SNMP. If a load balancer in your system, running on a Linux host, has SNMP and SSH ports open, Discovery might classify it based on the SSH port. This classification has priority over SNMP. To ensure that Discovery properly classifies your hardware load balancers, create a Discovery behavior for load balancers that includes SNMP but not SSH. Software load balancers are treated as applications. Credentials Configure SNMP credentials or (optionally) SSH credentials. Classifier, pattern, and probes Discovery uses these classifiers, probes, and pattern for F5 discovery: Classifier Trigger probes Pattern A10 Load Balancer Horizontal discovery probe: launches patterns A10 Load Balancer Data collected The following data is collected on the A10 Load Balancers [cmdb_ci_lb_a10] table. Label Field Name Serial Number serial_number The following data is collected on the Load Balancer Interface [cmdb_ci_lb_interface] table. Label Field Name Name name MAC Address mac_address Operational Status operational_status The following data is collected on the Load Balancer Pool [cmdb_ci_lb_pool] table. Label Field Name Name name The following data is collected on the Load Balancer Pool Member [cmdb_ci_lb_pool_member] table. Label Field Name Name name IP Address ip_address Service Port service_port The following data is collected on the Load Balancer Services [cmdb_ci_lb_service] table. Label Field Name Name name IP Address ip_address Port port Operational Status operational_status Install Status install_status The following data is collected on the DNS [cmdb_ci_dns_name] table. Label Field Name Name name IP Address ip_address Relationships created An A10 Discovery creates relationships between the application and the load balance service if the application CI exists. In this example from the dependency view (BSM map), an A10 load balancer is represented by these elements: Vip1: Virtual IP address that is the entry point for all business services attempting to contact the load balancer. vthunder: Actual A10 load balancer CI created by Discovery. webApp-group1: Group containing the web server pool members IBM web01 and IBM web02. Figure 1. A10 load balancer dependency view (BSM map) Discovery creates these relationships from the perspective of the load balancer group: Figure 2. A10 load balancer relationships ServiceWatch maps an A10 load balancer like this: Figure 3.
