'Which is the right package in the yum repo for Ops Agent on RHEL7?

I am trying to install the Ops Agent from the GCP yum repo: https://packages.cloud.google.com/yum/repos/

I see there are 4 different packages for this agent:

google-cloud-ops-agent-el7-x86_64-0
google-cloud-ops-agent-el7-x86_64-1
google-cloud-ops-agent-el7-x86_64-2
google-cloud-ops-agent-el7-x86_64-all

What is the difference between the suffixes, -0, -1, -2, and -all? I've tried looking through the docs but couldn't find anything, and I am confused over which one I should get.
