F5 load balancer sample configuration

Use the F5 load balancer to ensure seamless failover when TrueSight Operations Management is configured for high availability. The following topic provides information on how to prepare and configure F5 load balancer.

Note

This topic provides only a sample configuration of the F5 load balancer. BMC Quality Assurance department used this configuration for TrueSight Operations Management in high availability mode.
Your F5 configuration can vary depending on your requirements. For more information about F5 documentation, see https://support.f5.com/csp/knowledge-center/software

Terms used in this document

  • A node is a logical object on the BIG-IP system that identifies the IP address of a physical resource on the network. You can explicitly create a node, or you can instruct Local Traffic Manager to automatically create one when you add a pool member to a load balancing pool.
  • A load balancing pool is a logical set of devices, such as web servers, that you group together to receive and process traffic. Instead of sending client traffic to the destination IP address specified in the client request, Local Traffic Manager sends the request to any/available servers that are members of that pool.
  • Purpose of health monitors is check the health, performance and load. If a monitored device, link, or service does not respond within a specified timeout period, or the status indicates that service is down or performance is degraded or that the load is excessive, the BIG-IP system can redirect the traffic to another resource.
  • A virtual server is a traffic-management object on the BIG-IP system that is represented by an IP address and a service. Clients on an external network can send application traffic to a virtual server, which then directs the traffic according to your configuration instructions. The main purpose of a virtual server is often to balance traffic load across a pool of servers on an internal network.


To configure F5 load balancer, perform the following:

TrueSight App Visibility Portal and App Visibility Collector load balancer configuration in HA mode

In TrueSight Operations Management, the App Visibility Portal and App Visibility Collector components can be installed and configured in a High-Availability mode.  However, to manage the connection between the active and standby nodes, the App Visibility Portal and Collector components require a load balancer.  For more information, see App Visibility Manager high-availability deployment

Note

There is no specific load balancer requirement for the App Visibility Portal and App Visibility Collector components.  This document discusses the usage of the F5 load balancer.

Configuring an F5 load balancer is users responsibility, and the information in this document uses as a sample F5 load balancer configuration with App Visibility Portal and App Visibility Collector.  In addition, these steps and screen shots could vary depending on the version of the F5 load balancer.
