[RFE] Brick Utilization: threshold breached Alert needs to be generated for brick usage above 90%
Last modified: 2018-09-04 03:02:03 EDT
Description of problem: Currently when gluster volume usage (brick usage) goes above 75% an Alert is generated and in the dashboard the color changes to Amber. If the gluster volume (brick usage) goes above 90% the color in the dashboard changes to Red BUT there is no Alert for crossing the 90% usage. Version-Release number of selected component (if applicable): tendrl-monitoring-integration-1.5.4-14.el7rhgs.noarch How reproducible: Always Steps to Reproduce: 1.Identify gluster volume and write data into volume to exceed 75% threshold. 2.Tendrl Alert should be generated for all bricks in the volumes. Validate that in dashboard the color is now Amber for this volume/bricks. 3. In the case of CRS 3 Alerts will be generated and sent to specified email address, one for each brick (gluster hostname is now shown because this Alert was generated from customer tendrl installation). Brick utilization of <gluster_server_hostname>:|var|lib|heketi|mounts|vg_0bfd0da65ef15a9d75692a67b838cfc9|brick_c5e7ee1e0704c91888f04cfb4cb50017|brick in cluster 7bc6aa73-0c97-404b-88a2-077b5c77656a is 82.29 % which is above WARNING threshold (75 %) 4.Continue writing to gluster volume until 90% usage has been achieved. Validate that in the dashboard the color is now Red for this volume/bricks. Actual results: No additional Alert is sent for crossing the 90% usage value even though the color in dashboard is now Red. Expected results: Tendrl Alert should be sent for crossing the 75% usage AND for crossing the 90% usage (Green->Amber->Red). Additional info:
There are generated alerts when brick utilization is over 90%. --> VERIFIED Tested with: tendrl-ansible-1.6.1-3.el7rhgs.noarch tendrl-api-1.6.1-3.el7rhgs.noarch tendrl-api-httpd-1.6.1-3.el7rhgs.noarch tendrl-commons-1.6.1-3.el7rhgs.noarch tendrl-grafana-plugins-1.6.1-3.el7rhgs.noarch tendrl-grafana-selinux-1.5.4-2.el7rhgs.noarch tendrl-monitoring-integration-1.6.1-3.el7rhgs.noarch tendrl-node-agent-1.6.1-3.el7rhgs.noarch tendrl-notifier-1.6.0-1.el7rhgs.noarch tendrl-selinux-1.5.4-2.el7rhgs.noarch tendrl-ui-1.6.1-3.el7rhgs.noarch glusterfs-3.12.2-7.el7rhgs.x86_64
