Logging data

[PaddyB]

thanks for posting

I had held off trying the Influxdb option- I thought the Raspberry has enough to do without being a database server as well....

But by the sound of it, it does not use too much processor/memory ?
Are you using the SD card or an external USB drive for the database & how much space does it take up ?
I'm guessing it would be possible to write a query to delete old data- say over 30 days old- if disk space is an issue ?

Revisiting this again - influxdb was having a 'blip' of high CPU usage every few seconds, from just watching htop. Google came up with this after some searching which seems to solve that, it's floating around 2% CPU now in htop so much better >

Just change  a line in the config >

Code:

[monitor]

store-enabled = false

Also installed telegraf for monitoring the Pi but not really dug deep in there yet though looks very useful as an easy way to view what the pi is up to.
