Data collected by Discovery on load balancers Discovery can collect data about network routers, switches, and applications. Discovery supports data collection from the following applications and hardware: A10 Apache mod_jk and Apache mod_proxy Big-IP F5 Traffic Manager Cisco Citrix NetScaler HAProxy NGINX Alteon ACE Radware 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. Load balancer patternsStarting with the Jakarta release, Discovery uses out-of-box patterns to find some types load balancers for new instances (see table). These patterns perform the discovery for both new Jakarta instances and for upgrades.
