@grant1 That is odd - as that would indicate a 64bit kernel - which would be why the previous nodejs install failed, if it is really running 32bit.
Any chance you can also run getconf LONG_BIT and report back ? Thanks
Is that influxdb v2, rather than 1.8? V2 is supposed to run only on 64 bit, so if that does run it seems that raspbian desktop is a bit indeterminate as to whether it is 64 or 32.
I installed InfluxDB v2.3 (the latest) and set it up with Node-RED to populate it the same way as my "regular" NR+Influx system (regular = in production for many months, running on 64-bit Debian). So far, it looks / behaves exactly the same. I can try to install Grafana 64-bit as well and see how that goes.
