I've been trying to figure out a way to do this usefully and haven't had much success due to the nature of RRDs.
I have an environment where I need to have some sort of high availability for my RRD collector boxes. While its possible to use a SAN, that still leaves me with a single point of failure on the SAN box, which is less than ideal. Unfortunatly, it doesn't appear I can replicate RRDs without coping the entire file from one machine to another at certain intervals, which is a massive IO hit. I've heard rumblings of a SQL backend, but from what I've seen so far that only seems to be for fetching data from SQL, not updating. Does anybody have any suggestions for how one might approach active/standby redundancy with a large amount of RRDs? We only have about 15k RRDs currently, but I expect to be seeing over 100k in the next 6-8 months and I'd like to see if I can solve this problem before I have that kind of volume. Thanks, Dylan _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
