Raw log data consumption

(theresa) #1


this might seem to be an odd question
But is it possible to find out the size of raw log data that is currently being used (before it is ingested in the elasticsearch database)? With the help of the elasticsearch-hq or kopf plugin I can see that currently approx. 772gb are in the elasticsearch database. There seems to be an 1gb offset, because when I run “df -h” on the elasticsearch filesystem I can see that 773gb are currently used.

Hej @micsnare

the size on disk and the actual message size is not and will not be the same. Elasticsearch is a Database and add additional overhead.

Looking at your Graylog metrics can give you an idea of the volume you get.

currently having 68 shards and 17 indices (goal is to have a 90-days retention time)
the machine has the following specs: 10 vcores, 12GB memory and 1.5TB of storage

do you need more metrics?

Hej Theresa,

sorry to say - but you dropped out the important part. What timespan did you have in your 850 GB ?

Everything else is something we might look together if you have professional support but that is nothing i’ll cover in the community forum.

Hey Jan,

ah sorry, then I misunderstood you. I’m receiving logs since May 8th… so exactly a month today.
Don’t think I’ll be able to cover the 90-days retention period then :smiley:
