Hello.
I have an EPC 1522 running, with an influxdb database (he default implementation included in the Fw 2022.0.7), so far so good, but I would like to control the space of the DB, for that reason.
Where is the influxdb database stored inside the EPC-1522?

Hello carflomi,
the actual size of your database („bucket“) can be read with this function using a SSH connection (Putty):

1. Connect to your EPC using Putty as admin.
2. If not already done, create a new root user („sudo passwd root“) and define a passwort.
3. Log in as root („su“)
4. Read the actual size of your bucket using this following code: („sudo du -sh /opt/plcnext/.influxdbv2/engine/data/ID_OF_YOUR_BUCKET“)

You can find your bucket ID inside InfluxDB in the „Data“ tab.

Here is an example, I’ve read my database „OPC_UA_FIELD“ via SSH and it returned that my database is only 676 KB big.

Best regards,
Daniel
