Description Daniel Horák 2017-06-19 13:21:14 UTC 
Description of problem:
  Web browser (Firefox or Chrome) with opened Tendrl - Cluster Overview page consumes huge amount of memory after few hours.

Version-Release number of selected component (if applicable):
  tendrl-alerting-3.0-alpha.3.el7scon.noarch
  tendrl-api-3.0-alpha.4.el7scon.noarch
  tendrl-api-doc-3.0-alpha.4.el7scon.noarch
  tendrl-api-httpd-3.0-alpha.4.el7scon.noarch
  tendrl-commons-3.0-alpha.9.el7scon.noarch
  tendrl-dashboard-3.0-alpha.4.el7scon.noarch
  tendrl-node-agent-3.0-alpha.9.el7scon.noarch
  tendrl-performance-monitoring-3.0-alpha.7.el7scon.noarch

How reproducible:
  100%


Steps to Reproduce:
1. Prepare nodes for Ceph cluster and Tendrl server:
  - 1 Tendrl Server
  - 3 Ceph MONs
  - 4 Ceph OSDs with 10 free disks, two of them are configured as SSDs[1].
2. Install Tendrl Server and Tendrl nodes.
3. Create Ceph Cluster via Tendrl web UI.
4. Create fresh clean profile in Firefox and open there the Ceph cluster Overview page (Clusters -> <cluster name>)
5. Left it untouched for few hours.
6. Monitor the memory consumed by the browser.


Actual results:
  The browser starts to consume more and more memory.
  In my case after 5 hours fresh clean firefox profile with only the one tab opened consumes more than 5GB of RAM and more than 13GB of Virtual Memory! (see the attached screenshot of htop)

Expected results:
  Browser with opened any Tendrl page should consume reasonable amount of memory and should not consume more and more memory during few hours time frame.

I don't think this is valid anymore. This was raised when tendrl used to support ceph and dashboard was based on PatternFly. Now we have a grafana based dashboard and havn't seen this issue in recent past. Closing this issue.
