So I have been using Nagios/RRD for many years to collect/store data about my machines. I would like to be able to move some of this data over to elasticsearch so that I can do some analysis on it.
Does anyone know of a way to use logstash/beats/something else to take data from an RRD and put it into ES? I have messed around with the rrddump command in rrdtools, but it can be a mess.
Any help would be appreciated!
