A couple Marvel Overview Q - How CPU and Memory for a Cluster are calculated


(Tony Su) #1

Hello,
Have posted a screenshot of Marvel on my demo cluster
https://github.com/putztzu/Misc_images/blob/master/marvel_only.png

FYI Configuration
All nodes running on openSUSE 13.1/openjdk1.7
(On a single machine running VMware)
ES-Marvel-openSUSE
ES-LogstasthIndexer-Redis-LogstashShipper(ApacheParse)-netcat
ELASTICSEARCH-1 ES
ELASTICSEARCH-2 ES
ELASTICSEARCH-3 ES
ELASTICSEARCH-4 ES

Questions I have about what Marvel is displaying

Cluster Summary

  1. CPU usage of a cluster is interesting, is it an aggregate of cluster CPU
    resources, and is it supposed to be a realtime snaphot or
    mean/median/average/something else?

  2. Memory, similar Q to (1). Is this the aggregated cluster resources,
    total available and used, and is it current, peak or something else?

Thx,
Tony

Hi Tony,

The cluster summary shows a snapshot of the cluster, taken every 5 second.
The CPU numer is the total cpu usage of all the ES processes (100% == one
core). Memory is the total memory used by the JVM nodes & the total memory
available to them.

Cheers,
Boaz
