Load balancer: Citrix Netscaler Discovery of Citrix Netscaler load balancers is performed by SNMP. Requirements 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 Classifier Trigger probes Pattern Netscaler Load Balancer Horizontal discovery probe: launches patterns Netscaler Load Balancer Data collected The following data is collected on the Citrix Netscaler [cmdb_ci_lb_netscaler] table. Label Field Name Serial Number serial_number Operational Status operational_status The following data is collected on the Load Balancer Pool [cmdb_ci_lb_pool] table. Label Field Name Name name Load Balancing Method load_balancing_method 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 VLAN [cmdb_ci_lb_vlan] table. Label Field Name Name name Tag tag 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 Hit count hit_count Note: Discovery does not gather the load balancer interface information that is necessary to map the network path in Service Mapping. Service maps might not appear correct. To use patterns, verify that the correct pattern is specified in the horizontal pattern probe on the classifier. See Add the Horizontal Pattern probe to a classifier for instructions.
