We should remove the documentation for gwtop. It's essentially deprecated upstream since it doesn't function in a containerized environment and therefore has been replaced by a built-in prometheus exporter in 'ceph-iscsi'. See BZ1786453 for the related BZ to (re)add the iSCSI grafana dashboard to the Ceph dashboard (was in included in ceph-metrics).
Hi Amrita, In section 7.11. MONITORING THE ISCSI GATEWAYS: {storage-cluster} cluster now incorporates a generic metric gathering framework within the OSDs and MGRs to provide built-in monitoring. The metrics are generated within the {storage-cluster} cluster and there is no need to access client nodes to scrape metrics. "{storage-cluster} cluster" looks confusing. Can you look into it?
Hi Gopi, Thanks for your feedback, have rectified to {storage-product}. Block Device Guide 4: Jenkins preview: Section 7.11 https://jenkins.dxp.redhat.com/job/CCS/job/ccs-mr-preview/5978/artifact/preview/index.html Block Device Guide 5: SEction 10.10 Jenkins preview: https://jenkins.dxp.redhat.com/job/CCS/job/ccs-mr-preview/5979/artifact/preview/index.html Thanks Amrita
Document looks fine.
