Querying certain items doesn't work and results in a 422 error. These ones did not work for me:
kpi.lun.+.sp..readBandwidth
kpi.lun.+.sp..writeBandwidth
kpi.lun.+.sp.*.totalBandwidth

try use
-histpaths lun.+.sp..readBandwidth
-histpaths lun.+.sp..writeBandwidth
-histpaths lun.+.sp.*.totalBandwidth
