I want to keep trends about a table in my database. There are a handful of fields I am interested in less than a dozen. My idea is to send the values of those fields to rrd on a periodic basis and trend their values over time.
My big worry is the number of records in the database. It is my understanding that I would need a different rrd database for every record which means I might need hundreds of thousands of databases maybe even over a million. Is there a way to sore two dimensional data in a single RRD database? In addition to the cumbersome nature of having thousands of rrd files I am thinking I would not be able to ask questions like "this records are trending down" or "which record is trending fastest" etc. I was thinking I would get around that by keeping the aggregate indicators in both RRD and the relational database. Has anybody ever attempted such a thing before? Is there a better way to handle this kind of task. _______________________________________________ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
