iRule-based Instrumentation​

Pre-requisites​

  • You have sufficient permissions to add iRule to the Virtual Servers.
  • The Satellite has been successfully set up and is reachable from the BIG-IP LTM.

Installation​

To instrument your APIs from the LTM Virtual Servers, you need to:

  1. Download and configure the iRule script
  2. Add the iRule to the VirtualServers you want to instrument

Download and configure iRule Script​

  • Download the iRule script

  • Locate collector_host_ip and collector_host_port inside the script, and set them to appropriate values. Note that the virtual server should be able to reach to this IP.

Add the iRule to the VirtualServers you want to instrument​

  • In the BIG-IP Dashboard, go to, Local Traffic > iRules > iRule List
  • Click on Create and paste the downloaded iRule inside the Definition. Give the script a name and click on Finished
  • Next, go to, Local Traffic > Virtual Servers > Virtual Server List
  • Click on the virtual server which you want to instrument.
  • Under the Resources section, locate iRules. Click on Manage
  • Move the Levo's iRule script to Enabled section. Click on Finished.

The iRule script will start instrumenting and send the traces to Levo's Collector.
