With this you can change the --deltapos, --deltaneg, --failure-threshold, --window-length, --alpha, --beta and --gamma parameters. Also you can also set --gamma-deviation and it has a --aberrant-reset parameter (which are not included in rrd_hwreapply). This should be faster than rrd_hwreapply as it doesn't rebuild the whole rrd, but it is also less powerfull as you cannot change the --rralen and --season parameters with it.
