Created attachment 1351945 [details] Screenshot - duplicated hosts on Tendrl-Gluster-Hosts dasboard Description of problem: When Gluster Trusted Storage Pool is created using IP addresses (not hostnames), Grafana lists each host twice - by hostname and by IP address (see the attachment).

Prepare Gluster Cluster, use IP addresses in gdeploy configuration file (instead of hostnames): Example gdeploy configuration file: [hosts] 192.0.2.1 192.0.2.2 192.0.2.3 192.0.2.4 192.0.2.5 192.0.2.6 [peer] action=probe ignore_peer_errors=no 2. Install and configure Tendrl Server and Tendrl Node Agents. 3. Import Glsuter Cluster into Tendrl. 4. Open Grafana Tendrl-Gluster-Hosts dashboard. Actual results: Host Name selectbox contains each server twice, once listed by Hostname, second time listed by IP. (see screenshot) Expected results: Hosts should be listed only once by Hostname. Additional info:
Using IP Address to peer probe a gluster cluster is not a recommended configuration. Same with Tendrl as well.You need to use FQDN.
If I understand it correctly, using IPs for peer probe is not generally recommended, but supported Gluster configuration. So if the decision is not to fix this issue now, we should answer following question: What is the full impact of this kind of configuration for Tendrl? If it is only the duplicated visibility of hosts in selectbox on Grafana Tendrl-Gluster-Hosts Dashboard, then we can leave it for now as a known issue and do not limit the supported Gluster configurations for Tendrl. But if it might cause another unexpected issues, we have to properly and explicitly document, that this particular Gluster configuration is not supported and such cluster should not be imported into Tendrl.
At the moment I propose to explicitly document that this particular Gluster configuration is not supported as we are not recommending this to the customer.
Could you review this BZ, which we discussed on "RHGS WA with RHS One testing" meeting on 2018-03-05 and add here a comment with severity from RHSOne perspective? Thanks a lot for the feedback.
Could you recheck status of this BZ and add FiV if possible to move it to the ON QE state?
I've retested this bug with various scenarios consisting from: * peer probe done using FQDN or IP addresses * volume(s) created using FQDN or IP addresses And in all cases, each hosts on various Grafana dashboards (Hosts, Bricks) is properly listed only once (by FQDN or IP, depending how peer probe was done). Just small note related to: (In reply to Daniel Horák from comment #0) > Expected results: > Hosts should be listed only once by Hostname. The hosts are listed by FQDN/Hostname or IP - depending on how the peer probe for particular node was done, which seems to be reasonable. >> VERIFIED ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Version-Release number of selected components: Tendrl Server # cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.5 (Maipo) # rpm -qa | grep -e tendrl -e collectd -e gluster -e etcd | sort collectd-5.7.2-3.1.el7rhgs.x86_64 collectd-ping-5.7.2-3.1.el7rhgs.x86_64 etcd-3.2.7-1.el7.x86_64 libcollectdclient-5.7.2-3.1.el7rhgs.x86_64 python-etcd-0.4.5-2.el7rhgs.noarch rubygem-etcd-0.3.0-2.el7rhgs.noarch tendrl-ansible-1.6.3-3.el7rhgs.noarch tendrl-api-1.6.3-2.el7rhgs.noarch tendrl-api-httpd-1.6.3-2.el7rhgs.noarch tendrl-commons-1.6.3-3.el7rhgs.noarch tendrl-grafana-plugins-1.6.3-1.el7rhgs.noarch tendrl-grafana-selinux-1.5.4-2.el7rhgs.noarch tendrl-monitoring-integration-1.6.3-1.el7rhgs.noarch tendrl-node-agent-1.6.3-3.el7rhgs.noarch tendrl-notifier-1.6.3-2.el7rhgs.noarch tendrl-selinux-1.5.4-2.el7rhgs.noarch tendrl-ui-1.6.3-1.el7rhgs.noarch Gluster Storage Server # cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.5 (Maipo) # cat /etc/redhat-storage-release Red Hat Gluster Storage Server 3.4.0 # rpm -qa | grep -e tendrl -e collectd -e gluster | sort collectd-5.7.2-3.1.el7rhgs.x86_64 collectd-ping-5.7.2-3.1.el7rhgs.x86_64 glusterfs-3.12.2-8.el7rhgs.x86_64 glusterfs-api-3.12.2-8.el7rhgs.x86_64 glusterfs-cli-3.12.2-8.el7rhgs.x86_64 glusterfs-client-xlators-3.12.2-8.el7rhgs.x86_64 glusterfs-events-3.12.2-8.el7rhgs.x86_64 glusterfs-fuse-3.12.2-8.el7rhgs.x86_64 glusterfs-geo-replication-3.12.2-8.el7rhgs.x86_64 glusterfs-libs-3.12.2-8.el7rhgs.x86_64 glusterfs-rdma-3.12.2-8.el7rhgs.x86_64 glusterfs-server-3.12.2-8.el7rhgs.x86_64 gluster-nagios-addons-0.2.10-2.el7rhgs.x86_64 gluster-nagios-common-0.2.4-1.el7rhgs.noarch libcollectdclient-5.7.2-3.1.el7rhgs.x86_64 libvirt-daemon-driver-storage-gluster-3.9.0-14.el7_5.2.x86_64 python2-gluster-3.12.2-8.el7rhgs.x86_64 tendrl-collectd-selinux-1.5.4-2.el7rhgs.noarch tendrl-commons-1.6.3-3.el7rhgs.noarch tendrl-gluster-integration-1.6.3-2.el7rhgs.noarch tendrl-node-agent-1.6.3-3.el7rhgs.noarch tendrl-selinux-1.5.4-2.el7rhgs.noarch vdsm-gluster-4.19.43-2.3.el7rhgs.noarch
Boob looks good to me now.
I am really sorry about the bad word I meant Bobb(In reply to Shubhendu Tripathi from comment #15) > Boob looks good to me now.
