level=error msg="Error during scrape: too many requests"

[urbaman]

Hi,

Deployed in kubernetes, can't seem to be able to scrape, while the serverinfo page responds via blowser. It seems the exporter keeps running every 5s (default timeout) even if I try to set it to 30s, and it's too frequent.

Running Nextcloud 28.0.1.1

Found out it's about brute-force, I'll check it out, both for this and credentials.

[urbaman]

Ok, it actually was MFA, now disabled for the exporter user.

Is there a way to use the app_password? Is it the token (it doesn't seem to work)? I wouldn't leave an admin user without MFA.

Thank you.

Token authentication and app-passwords are not the same thing. Have you seen the documentation about token authentication already?

Second, the timeout configured in the exporter does not configure how often it is scraped by Prometheus (which is what controls how often it tries to reach Nextcloud). This is done in the scrape configuration of Prometheus.

Hi @xperimental

Sorry for the late response, I solved the "too many requests" thing, I'll close this up and open a new one for the credentials problem.

Thank you.
