Long Term data not or only written after checking the same?

[Chris]

@Chris

I suppose disabling “Query Logging” via the (Admin) GUI leads to the mentioned setting in the /etc/pihole/setupVars.conf - right?

Yes, that toggle sets the configuration to disable queries being written to the log files.

I understood that disabling “Query Logging” via the (Admin) GUI only disables the availability of displaying the DNS request “real time” (located under Tools @ the (Admin) GUI - not sure, haven’t used that for ages) and consequently reduces write operations - am I mistaken in this regards?

No, that is correct, no queries are being logged.

Sorry, for being nagging but this is really confusing to me.

According to this discussion I would expect that the “Disable Query Logging” button (which I pressed months ago) does NOT stop the long term data logging.

@Chris

In case I am not mistaken I’d be happy to understand how a flushing of the logs can impact the long term data (given that this is written regularly, usually every minute).

If there’s nothing being logged then there’s nothing to go in the long term database.

Is there maybe any easy way to check the sanity of an installation?

(eg recommended log files to check for failed write operations or such,…?)

Everything looks to be operating as requested. Logging was disabled and this is what happens when you stop logging queries.

I didn't change the setting at all - for the time until Feb. 26 ~20:00 the long term data shows queries, and starting from Feb 27 ~20:00 (after I pressed the "Flush logs" button and did a reboot) it also shows queries (as shown in the attached jpg)

My apologies again, but I really don't get my head around this...
