Description Heðin 2020-06-03 12:34:00 UTC 
Description of problem:
https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/4/html-single/block_device_guide/index#monitoring-the-iscsi-gateways-block refers to installing 
yum install ceph-iscsi-tools
But this is not compatable with rhcs-4.0

Also, the documentation does not state how gwtop is to be installed in a containeried igw deployment.

Version-Release number of selected component (if applicable):
rhcs-4.0 on RHEL-8.2

How reproducible:
100%

Steps to Reproduce:
1. Deploy IGW containerized on RHEL8
2. Try to follow the documenation for deploying igw monitoring.


Actual results:
#1 Packages can't be installed.
#2 Documentation states 
"Information from the Linux-IO target (LIO) PMDA is used to list each exported RBD image with the connected client and its associated I/O metrics."
But this contradicts the state-less nature of the containers and the fact that the ceph-iscsi package is not installed on the physical node.

Expected results:
#1 igw monitoring by following documentation
#2 After reading the documnetation, the reader should have a clear understanding of the interaction between the relevant services.
