tip: you can nest groups if you would like. Assign the sub-groups to the main group that is used in your persistence config (the gInfluxDB)
For example:
Put all systeminfo items in a gSysInfo group and then make that group a member of the big gInfluxDB Group.
Group gInfluxDB
Group gSysInfo (gInfluxDB)
itemtype itemname "labeltext [stateformat]" <iconname> (gSysInfo) [...]
