Load Balance Traffic to ESM Servers

Using a load balancer, you can balance traffic from Traps agents across your ESM Servers. While load balancing is supported with ESM Servers, the ESM Console must not be behind a load balancer.
  1. Set up your load balancer.
    Configure the load balancer in sticky mode: When the agent directs a request to a specific ESM Server, a load balancer configured in this mode will send all subsequent requests to the same ESM Server. See the instructions for your load balancer vendor.
  2. Configure the ESM Servers for load balancing.
    For each ESM Server for which you want to load balance traffic, you must specify the IP address of the load balancer as the primary internal IP address for the server instead of the auto-detected IP address for the ESM server. The Traps agent builds the list of addresses based on the addresses you configure for the ESM Server.
    1. Select
      Multi ESM
    2. Select the row of the ESM Server.
      The ESM Console displays the settings associated with the server.
    3. Edit
      the settings for the ESM Server.
    4. Override the auto-detected IP address of the ESM Server to specify the FQDN of the load balancer as the primary
      Internal Address
      . If you are not using SSL for communication to the load balancer, you must also specify the IP address of the load balancer as the secondary
      External Address
    5. Save
      your changes.
  3. Select a server that is configured with the load balancer address. Traps agents installed using this package will establish connections through the load balancer instead of attempting to connect directly to an ESM Server.
