Add a new sampled mode

Reported by: andreu Owned by: andreu
Priority: major Milestone: Release 0.0.13
Component: core Version:
Keywords: Cc:


In multi-chassis networks, the NetFlow exporters may be configured with differents sampling due to the platform/card type or OS version. In renetcol, for a prefix we have only one RRD file with the sampling value. She's tagged in the file name (127_0_0_0_16_10.rrd for prefix with sampling value 10 aka 1 packet on 10). This sampling value was get from optional template in the first launch phase of renetcol. We made the choice in release 0.0.13 to keep only one file per prefix. In this case, we need to know the sampling value for each prefix used in aggregation mode before the start of renetcol. These values will be get from the prefix list, the file will have the new format : <prefix> <mask> <sampling>. If sampling values are differents (routers!=file), the amount of bytes and numbers of packets will be tuned. The flow numbers can not be tuned, so some information will lost in this release...
