losing metrics

[Josefo Serra]

Hi, I'm losing metrics between scraps and I understand that it's because I scrape every 10 minutes and they must "expire" or something. Could someone tell me which parameter I have to modify?

Thanks!

The maximum scrape interval should be 2 minutes, so you want to adjust
those jobs to scrape every 2 minutes instead of 10.

Hi Stuart, thanks for your time!
The problem I have is that with script_exporter I make database queries that normally take between 5 and 8 minutes and can reach 15 On the other hand I am saving that information in a database and I don't really need that much data

In that situation of very slow scrapes, I'd suggest two options.

Either split the queries up if possible, which would allow things to be parallelised.

Alternatively, run the queries via cron or a script and write the results to the filesystem and then use the node exporter's textfile collector. Then you can scrape say ever 30 seconds so you won't have issues with staleness.
