I'm monitoring my Debian GNU/Linux server with Munin monitoring software. I was wondering whether I could export the raw data used to generate Munin charts?
I want to do some in-depth statistical analysis for example on outgoing traffic. CSV or some similar table format preferred.
I was reading in some forums that the data is stored in some RRDtool database format. It can be exported using rrdump or rrdxport but both are rather used for RRD-internal ex- and import and only dump XML files.
Did anyone try to extract the data to CSV and if so, how?
