Description gowtham 2018-03-22 14:28:12 UTC

Description of problem:
Monitoring-integration sync-interval time is fetched from gluster_ns in central-store. But before cluster import gluster_ns is not created in central store. So monitoring-integration sync thread is keep executed without any break, So it consumes a lot of CPU and memory resources.

Version-Release number of selected component (if applicable):


How reproducible:
Install and start monitoring-integration before import cluster and check CPU and memory resource consumption.

Steps to Reproduce:
1.
2.
3.

Actual results:
monitoring-integration consumes a lot of CPU and memory

Expected results:
monitoring-integration should consume less CPU and memory

Comment 2 Martin Bukatovic 2018-03-28 08:28:21 UTC

Could you provide more details about:

* Version where the bug is present.
* Is it possible to reproduce this on previously released RHGS WA?
* Link to upstream merge request.

Comment 3 gowtham 2018-03-28 15:41:53 UTC

It is possible to reproduce in all previous released RHGS, After executing ansible script for installing tendrl components, check the CPU and memory resource consumption using a command top.

Comment 4 gowtham 2018-03-28 16:06:39 UTC

Check cpu and memory resource which is used by monitoring-integration in server node, it is reproducible in rhgs 1.6.1-1

Comment 5 gowtham 2018-03-28 16:43:22 UTC

sorry, In version 3.3.1 it can be reproducible

Comment 6 gowtham 2018-03-28 16:43:31 UTC

sorry, In version 3.3.1 it can be reproducible

Comment 7 gowtham 2018-03-28 17:14:57 UTC

I meant 1.6.1-1 is actually RHGS-WA NVR 1.6.1-1

Comment 10 Daniel Horák 2018-05-15 09:28:07 UTC

Reproduced on tendrl-monitoring-integration-1.6.1-1.el7rhgs.noarch.

Comment 11 Daniel Horák 2018-05-15 10:14:26 UTC

Tested and verified on tendrl-monitoring-integration-1.6.3-2.el7rhgs.noarch.

CPU and memory consumption of tendrl-monitoring-integration service is constantly bellow 1%.

# ps -p $(echo $(ps aux | grep [t]endrl-monitoring-integration | awk '{print $2}') | sed 's/ /,/') -o %cpu,%mem,cmd -h;
 0.4  0.3 /usr/bin/python /usr/bin/tendrl-monitoring-integration

>> VERIFIED
