Wang Haihua commented on SPARK-21157:
-------------------------------------
Dose the include the RES memory of one executor?
It does useful to trace memory usage. We implementa a simple demp (Collect the
RES memory usage by simulating the YARN container memory monitor and send the
metrics by heartbeat to driver ) one year ago, for we need collect real memory
usage for statistics of cluster and application optimization.
> Report Total Memory Used by Spark Executors

> Key: SPARK-21157
> URL: https://issues.apache.org/jira/browse/SPARK-21157
> Project: Spark
> Issue Type: Improvement
> Components: Input/Output
> Affects Versions: 2.1.1
> Reporter: Jose Soltren
> Attachments: TotalMemoryReportingDesignDoc.pdf
>
>
> Building on some of the core ideas of SPARK-9103, this JIRA proposes tracking
> total memory used by Spark executors, and a means of broadcasting,
> aggregating, and reporting memory usage data in the Spark UI.
> Here, "total memory used" refers to memory usage that is visible outside of
> Spark, to an external observer such as YARN, Mesos, or the operating system.
> The goal of this enhancement is to give Spark users more information about
> how Spark clusters are using memory. Total memory will include non-Spark JVM
> memory and all off-heap memory.
> Please consult the attached design document for further details.
