Hi everyone,

I have successfully managed to install Grafana and InfluxDB database on IOT2050. But there are a couple of things that are not clear to me. Maybe, some of you guys, have already accomplished management of InfluxDB on IOT20x0 or other Linux based devices.

First question:

How much space for DB data is available on IOT? Is it the size of the card SD or some internal memory on which the data is saved?

Second question:

How could I check, how much of storage have left and how much has already been used by data from InfluxDB?

Third question:

Do you maybe have some practical experience on how to calculate the retention policy time to avoid overlapping pieces of data?

Basically, I'm creating an application that reads the data from another device and writes it to InfluxDB through Node-Red. I want to adjust the retention policy to it as I'm doing it for the first time.

Thanks in advance,
