How to get statistic data from teamcity?

Question

I'd like to get some statistics data from TeamCity. I don't know if It's better to do this using TeamCity REST API or by queering TeamCity Database to get the data I need.

Can someone advice me which one is better ? FYI: I tried to use TeamCity Restful web services but if I request a project containing a lot of build configs, I get a timeout exception :

iagnostic.web.DiagnosticFilter - Request processing took too long: 192577 ms, request: GET '/app/rest/builds/?locator= ...

TeamCity version: 9.1.1(build 37059)

Answer 1

I finally used REST API. I get failed tests of the last build for each buildConfig.
