> Key: MESOS-813
> URL: https://issues.apache.org/jira/browse/MESOS-813
> Project: Mesos
> Issue Type: Improvement
> Components: cli
> Reporter: Bernardo Gomez Palacio
> Assignee: Bernardo Gomez Palacio
> Priority: Minor
> Labels: cli

> Rationale:
> As a CLI User I should be able to know how much memory/resources the Cluster has available before activating a framework. The Use Case arises when several CLI Users are interacting with Shark while the Cluster is already running additional frameworks. Ideally a CLI Users knows the available memory such that they can set a sensitive SPARK_MEM value. This will help reduce the number of Shark Queries hanging waiting for resources that they not necessarily require.
> Implementation suggestion.
> Will be simple to follow the mesos-ps script example to read the master/stats.json endpoint to present such metrics. The script could be mesos-stats and receive the specific metric you are interested in, should default to all.
> Potential enhancement could be an argument that loops the command such that we have a continuos feed of the stats in the cli.
