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.
