> Metrics: Add a global setting to enable/disable Metrics view
> ------------------------------------------------------------
>
> Key: CLOUDSTACK-9699
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9699
> Project: CloudStack
> Issue Type: Improvement
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: UI
> Affects Versions: 4.7.0, 4.8.0, 4.9.0
> Reporter: Rashmi Dixit
> Assignee: Rashmi Dixit
> Fix For: 4.10.0.0
>
> Attachments: enable-metrics-flag.PNG, metrics-disabled.PNG,
> metrics-enabled.PNG
>
>
> The Metrics view for each type of entity basically fires APIs and calculates
> required values on the client end. For e.g. to display memory usage etc at
> the zone level, it will fetch all zones. For each zone it will fetch
> pods->cluster->host->VMs
> For a very large Cloudstack installation this will have a major impact on the
> performance.
> Ideally, there should be an API which calculates all this in the backend and
> the UI should simply show the values. However, for the time, introduce a
> global setting called enable.metrics which will be set to false. This will
> cause the metrics button not to be shown on any of the pages.
> If the Admin changes this to true, then the button will be visible and
> Metrics functionality will work as usual.
