@bentzimortaboola The error (Execution canceled by operator
) seems to be rather specific to Vertica. I'm not sure if you had a look here already. In this case context deadline exceeded
likely means that SQL-exporter hasn't received any response within a given timeout. You can try to increase that timeout via configuration or optimize your query to see if it helps.
With regards to the debug logs, it seems there is no such an option as debug messages have to be placed in the code beforehand. Since you've added Vertica driver, you can check that there are not many debug log lines available in the code. Alternatively, you can try to use /debug/pprof
or put debug messages yourself for further digging.
Unfortunately, it's not that easy to help to address this issue, since there's no easy way to spin up a free Vertica cluster.

Yes I am aware of the error.
- How do I control the query timeout? (want to validate it's the root cause)
- Vertica is free till 1TB
Thanks

@bentzimortaboola You can try to increase scrape_timeout
in the configuration file.
Another approach would be to enable debug log levels provided by the Vertica driver itself (if you use the official one).
