Description Lubos Trilety 2017-11-29 14:22:23 UTC

Description of problem:
There's ambiguity in uses of decimal and binary metric for capacity in Grafana as both are used:

E.g.
tendrl-gluster-bricks.json
"The Capacity Available panel displays the available capacity for a given volume."
uses binary metric powers of 1024 - "format": "bytes", while
"The Weekly Growth Rate panel displays the forecasted weekly growth rate for capacity utilization computed based on daily capacity utilization."
uses decimal pwers of 1000 - "format": "decbytes"


Version-Release number of selected component (if applicable):
tendrl-monitoring-integration-1.5.4-8.el7rhgs.noarch

How reproducible:
100%

Steps to Reproduce:
1. Install tendrl-monitoring-integration package
2. Look on json files in /etc/tendrl/monitoring-integration/grafana/dashboards/ directory

Actual results:
bytes, kbytes and decbytes is used for capacity metrics

Expected results:
Only decimal or binary metric should be used for any capacity metric. It should be unified on all dashboards.

Not critical to address at the point of time. Proposing to move out to a future release.

Comment 3 Filip Balák 2018-05-11 12:29:32 UTC

Only binary metric is used for capacity metrics:
tendrl-gluster-at-a-glance uses kbytes
tendrl-gluster-bricks uses bytes
tendrl-gluster-hosts uses bytes
tendrl-gluster-volumes uses kbytes
--> VERIFIED
