I am Using Logstash, Redis and Elastic Search using the shipper and indexer
configuration.
Kindly tell me in detail the nature of each of the above in terms of CPU
bound or I/O bound jobs or network bound, so that I can decide which
component to run on which system.
What I thought of is that Redis is IO bound, and ES is CPU bound. In that
case, should run Redis on a machine, the indexer which filters on another,
and ES on another separate machine. Is it right?
Kindly explain the nature of each.
Any ideas will be appreciated.
