Ok, let me explain in more detail :- I have a requirement to write gathered data from a small cluster (about 40 computers). The number of metrics to be gathered is low (about 6-10). These metrics need to be stored indefinitely. We also want to process the data in a real-time manner, that is - each insert of data results in some operations, the results of which are used in taking meal-time decisions about the configuration/allocation of the cluster.
Having the data in a Relational DB makes it far easier to perform complex operations on the stored data. This is the main reason why we want it in a DB. This is all for a research project into cluster computing. The growing size of the Data is not really an issue for us as we can truncate it to whatever we want. We already know that an rrd can be dumped to xml or whatever, but we specifically want data to be written directly to a DB. I hope that answers all the queries. :) Thanks and regards Arjun On 2/24/06, michal <[EMAIL PROTECTED]> wrote: > > Arjun napisał(a): > > Hi Folks, > > > > I have a requirement to integrate ganglia to a DB such as MySql so that > > gmetad should store retreived data in > > MySql instead of an RRD. > > You can easyly dump RRD file to XML (rrdtool dump). > Then parse XML file and put the data anywhere you want. > > But keep in mind that badatabse will growing up if you just add new > records.
