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.

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.

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.
