hash entry called `sources` which lists +IP addresses and the number of times they appeared. + +Metric `dnscap-rssm-aggregated-sources` has a hash entry called `aggregated-sources` +which lists the aggregated IPv6 addresses by a /64 net and the number of times +it has appeared. + +## Merge Tool + +The Perl script `dnscap-rssm-rssac002` is included and installed with `dnscap` +and can be used to multiple combine RSSM plugin RSSAC002v3 YAML output files +into one file. + +The script will merge and remove metric specific to this plugin and replace +others to fill in correct values for the new
