   This file has two environment variables that represent BIG-IP passwords, BIGIP_PASSWORD_1 and BIGIP_PASSWORD_2. If you have more than two BIG-IP passwords, you will need to add them here.

+  This is the equivalent of the services/otel_collector/receivers.yaml file. You will need to list all BIG-IPs to be monitored, along with their settings, in this file (within the "receivers.yaml" section). The following is an example that shows how to include two BIG-IP devices. (Additional devices would be added to the end as bigip/3, bigip/4, etc.)
 
-  You will also need to ensure these reference are included in the list of BIG-IPs (i.e., "bigip/1", "bigip/2", etc.) in the receivers subsection under pipelines.yaml section (also in this file). The pipelines.yaml section of this file will look like the following:
