 |
|
anyone know how to implement this?
I've been testing the 1-min polling (thanks to Tekbot for his awesome tutorial) feature, and am now running into server slowness issues...
iostat shows spikes of 7k writes/sec, and I would think this is affecting performance of the server... but then how to set this up, and how to copy the data from the volatile ramdisk to persistent storage...? |

ps. Avoid MLC, it's unreliable for RRDtool. |

Thanks,
hmm.. I wonder how much one of these go for, and if it has been proven to work in a SUSE environment... |

80GB == 2900
160GB == 7200
Not cheap, but if you have a Large system, you need at least one.
