Depending on how you use Elasticsearch and Marvel, you may find out that Marvel itself is collecting so much data for statistics that it's eclipsing the actual data you want to store on Elasticsearch.
You have a few approaches to handle that:
Deleting old indices by hand
Marvel names its indices quite nicely (one for each day) so it's easy to delete only those that you don't need anymore.
The following command (executed from Sense) will delete all Marvel indices for September/2015:
Preventing Marvel from collecting data altogether
You will still be able to use Sense
Set the following config option on
elasticsearch.yml config file:
# disable from from collecting # statistics data altogether marvel.agent.enable: false
