Impact of marvel on performance


(Deep-2) #1

Hi,
What is the impact of Marvel on elastic search performance. I have a single
node elastic search deployment and I have installed marvel plugin. It seems
that marvel also creates indexes on the node.

How big is the marvel index and if the UI queries that index say every 10
secs will it adversely impact performance of elastic search.

Please guide.

Regards,
Deep

The Marvel indices tend to be small (you only have 1 node and I therefore
assume not too many indices). It will also have a little memory signature,
if you are using the UI. Marvel creates a new index every day, so will know
within a day how big it gets for you. You need to decide how many days of
data you want to keep and delete old ones. Curator
(github.com/elasticsearch/curator ) is a handy tool for that.

As far as search performance goes - it shouldn't have any serious impact
and if you don't have the marvel UI open it will have no impact at all.

Cheers,
Boaz
